NOTES TO FINANCIAL STATEMENTS
March 31, 2005
(Unaudited)

The unaudited financial statements contained herein include, in
the opinion of management, all adjustments necessary for a fair
presentation of the results of operations and financial condition
of Dean Witter Cornerstone Fund II (the ?Partnership?).  The
financial statements and condensed notes herein should be read in
conjunction with the Partnership's December 31, 2004 Annual Report
on Form 10-K.  Certain reclassifications have been made to the
prior year?s financial statements to conform to the current year
presentation.  Such reclassifications have no impact on the
Partnership?s reported net income (loss).

1.  Organization
Dean Witter Cornerstone Fund II is a New York limited partnership
organized in 1983 to engage in the speculative trading of futures
contracts, options on futures contracts, and forward contracts on
foreign currencies and other commodity interests.  The Partnership
is one of the Dean Witter Cornerstone Funds, comprised of the
Partnership, Dean Witter Cornerstone Fund III, and Dean Witter
Cornerstone Fund IV.



<page> DEAN WITTER CORNERSTONE FUND II
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

The Partnership?s general partner is Demeter Management
Corporation (?Demeter?). The non-clearing commodity broker is

Morgan Stanley DW Inc. (?Morgan Stanley DW?).  The clearing
commodity brokers are Morgan Stanley & Co. Incorporated (?MS &
Co.?) and Morgan Stanley & Co. International Limited (?MSIL?).
Demeter, Morgan Stanley DW, MS & Co., and MSIL are wholly-owned
subsidiaries of Morgan Stanley.  The trading managers to the
Partnership are Northfield Trading L.P. and John W. Henry &
Company, Inc. (individually, a ?Trading Manager?, or
collectively, the ?Trading Managers?).

2.  Related Party Transactions
The Partnership's cash is on deposit with Morgan Stanley DW, MS &
Co., and MSIL in futures, forwards, and options trading accounts
to meet margin requirements as needed.  Monthly, Morgan Stanley DW
pays the Partnership interest income equal to 80% of its average
daily Net Assets at a rate equal to the average yield on 13-week
U.S. Treasury bills. The Partnership pays brokerage commissions to
Morgan Stanley DW.






<page> DEAN WITTER CORNERSTONE FUND II
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

3.  Financial Instruments
The Partnership trades futures contracts, options on futures
contracts, and forward contracts on foreign currencies and other
commodity interests.  Futures and forwards represent contracts for
delayed delivery of an instrument at a specified date and price.
Risk arises from changes in the value of these contracts and the
potential inability of counterparties to perform under the terms
of the contracts.  There are numerous factors which may
significantly influence the market value of these contracts,
including interest rate volatility.

The market value of exchange-traded contracts is based on the
settlement price quoted by the exchange on the day with respect
to which market value is being determined.  If an exchange-traded
contract could not have been liquidated on such day due to the
operation of daily limits or other rules of the exchange, the
settlement price shall be the settlement price on the first
subsequent day on which the contract could be liquidated.  The
market value of off-exchange-traded contracts is based on the
fair market value quoted by the counterparty.

The Partnership?s contracts are accounted for on a trade-date
basis and marked to market on a daily basis.  The Partnership
accounts for its derivative investments in accordance with the
<page> DEAN WITTER CORNERSTONE FUND II
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

provisions of Statement of Financial Accounting Standards No.
133, ?Accounting for Derivative Instruments and Hedging
Activities? (?SFAS No. 133?).  SFAS No. 133 defines a derivative
as a financial instrument or other contract that has all three of
the following characteristics:

1)	One or more underlying notional amounts or payment
provisions;
2)	Requires no initial net investment or a smaller initial net
investment than would be required relative to changes in
market factors;
3)	Terms require or permit net settlement.

Generally, derivatives include futures, forward, swaps or options
contracts, and other financial instruments with similar
characteristics such as caps, floors, and collars.

The net unrealized gains (losses) on open contracts, reported as a
component of ?Equity in futures interests trading accounts? on the
Statements of Financial Condition, and their longest contract
maturities were as follows:

Dec. 31, 2004	622,026	1,388,707	2,010,733	Dec. 2005	Mar. 2005

The Partnership has credit risk associated with counterparty non-
performance.  The credit risk associated with the instruments in
which the Partnership trades is limited to the amounts reflected
in the Partnership's Statements of Financial Condition.



The Partnership also has credit risk because Morgan Stanley DW, MS
& Co., and MSIL act as the futures commission merchants or the
counterparties, with respect to most of the Partnership?s assets.
Exchange-traded futures, forward, and futures-styled options
contracts are marked to market on a daily basis, with variations
in value settled on a daily basis. Morgan Stanley DW, MS & Co.,
and MSIL, each as a futures commission merchant for the
Partnership?s exchange-traded futures, forward, and futures-styled
options contracts, are required, pursuant to regulations of the
Commodity Futures Trading Commission (?CFTC?), to segregate from
their own  assets, and for the sole benefit of their commodity
customers, all funds held by them with respect to exchange-traded
futures, forward, and futures-styled options contracts, including
an amount equal to the net unrealized gains (losses) on all open
<page> DEAN WITTER CORNERSTONE FUND II
NOTES TO FINANCIAL STATEMENTS (CONCLUDED)

futures, forward, and futures-styled options contracts, which
funds, in the aggregate, totaled $15,888,244 and $17,301,303 at
March 31, 2005 and December 31, 2004, respectively. With respect
to the Partnership?s off-exchange-traded forward currency
contracts, there are no daily exchange-required settlements of
variation in value, nor is there any requirement that an amount
equal to the net unrealized gains (losses) on open forward
contracts be segregated.  However, the Partnership is required to
meet margin requirements equal to the net unrealized loss on open
contracts in the Partnership accounts with the counterparty,
which is accomplished by daily maintenance of the cash balance in
a custody account held at Morgan Stanley DW for the benefit of MS
& Co. With respect to those off-exchange-traded forward currency
contracts, the Partnership is at risk to the ability of MS & Co.,
the sole counterparty on all such contracts, to perform. The
Partnership has a netting agreement with MS & Co. This agreement,
which seeks to reduce both the Partnership?s and MS & Co.?s
exposure on off-exchange-traded forward currency contracts, should
materially decrease the Partnership?s credit risk in the event of
MS & Co.?s bankruptcy or insolvency.






<page> Item 2. MANAGEMENT?S DISCUSSION AND ANALYSIS OF FINANCIAL
        CONDITION AND RESULTS OF OPERATIONS

Liquidity.  The Partnership deposits its assets with Morgan
Stanley DW as non-clearing broker and MS & Co. and MSIL as
clearing brokers in separate futures, forwards, and options
trading accounts established for each Trading Manager.  Such
assets are used as margin to engage in trading and may be used as
margin solely for the Partnership?s trading. The assets are held
in either non-interest bearing bank accounts or in securities and
instruments permitted by the CFTC for investment of customer
segregated or secured funds.  Since the Partnership?s sole purpose
is to trade in futures, forwards, and options, it is expected that
the Partnership will continue to own such liquid assets for margin
purposes.

The Partnership?s investment in futures, forwards, and options
may, from time to time, be illiquid.  Most U.S. futures exchanges
limit fluctuations in prices during a single day by regulations
referred to as ?daily price fluctuations limits? or ?daily
limits?.  Trades may not be executed at prices beyond the daily
limit.  If the price for a particular futures or options contract
has increased or decreased by an amount equal to the daily limit,
positions in that futures or options contract can neither be taken
nor liquidated unless traders are willing to effect trades at or
within the limit.  Futures prices have occasionally moved the
daily limit for several consecutive days with little or no
trading.  These market conditions could prevent the Partnership
<page> from promptly liquidating its futures or options contracts
and result in restrictions on redemptions.

There is no limitation on daily price moves in trading forward
contracts on foreign currencies.  The markets for some world
currencies have low trading volume and are illiquid, which may
prevent the Partnership from trading in potentially profitable
markets or prevent the Partnership from promptly liquidating
unfavorable positions in such markets, subjecting it to
substantial losses.  Either of these market conditions could
result in restrictions on redemptions.  For the periods covered by
this report, illiquidity has not materially affected the
Partnership?s assets.

There are no known material trends, demands, commitments, events,
or uncertainties at the present time that are reasonably likely to
result in the Partnership?s liquidity increasing or decreasing in
any material way.

Capital Resources.  The Partnership does not have, nor expects to
have, any capital assets.  Redemptions of units of limited
partnership interest (?Unit(s)?) in the future will affect the
amount of funds available for investments in futures, forwards,
and options in subsequent periods. It is not possible to estimate
the amount, and therefore the impact, of future outflows of Units.

<page> There are no known material trends, favorable or
unfavorable, that would affect, nor any expected material changes
to, the Partnership?s capital resource arrangements at the present
time.

Off-Balance Sheet Arrangements and Contractual Obligations.  The
Partnership does not have any off-balance sheet arrangements, nor
does it have contractual obligations or commercial commitments to
make future payments that would affect its liquidity or capital
resources.

Results of Operations
General.  The Partnership?s results depend on the Trading Managers
and the ability of each Trading Manager?s trading program(s) to
take advantage of price movements in the futures, forwards, and
options markets.  The following presents a summary of the
Partnership?s operations for the three month periods ended March
31, 2005 and 2004, and a general discussion of its trading
activities during each period.  It is important to note, however,
that the Trading Managers trade in various markets at different
times and that prior activity in a particular market does not mean
that such market will be actively traded by the Trading Managers
or will be profitable in the future. Consequently, the results of
operations of the Partnership are difficult to discuss other than
in the context of the Trading Managers? trading activities on
behalf of the Partnership during the period in question. Past
performance is no guarantee of future results.
<page> The Partnership?s results of operations set forth in the
financial statements on pages 2 through 11 of this report are
prepared in accordance with accounting principles generally
accepted in the United States of America, which require the use of
certain accounting policies that affect the amounts reported in
these financial statements, including the following:  The
contracts the Partnership trades are accounted for on a trade-date
basis and marked to market on a daily basis.  The difference
between their cost and market value is recorded on the Statements
of Operations as ?Net change in unrealized trading profit (loss)?
for open (unrealized) contracts, and recorded as ?Realized trading
profit (loss)? when open positions are closed out.  The sum of
these amounts constitutes the Partnership?s trading results.  The
market value of a futures contract is the settlement price on the
exchange on which that futures contract is traded on a particular
day. The value of foreign currency forward contracts is based on
the spot rate as of the close of business.  Interest income, as
well as management fees, incentive fees, and brokerage commissions
expenses of the Partnership are recorded on an accrual basis.

Demeter believes that, based on the nature of the operations of
the Partnership, no assumptions relating to the application of
critical accounting policies other than those presently used
could reasonably affect reported amounts.



<page> For the Quarter Ended March 31, 2005
The Partnership recorded total trading results including interest
income totaling $(2,566,837) and expenses totaling $407,970,
resulting in a net loss of $2,974,807 for the quarter ended March
31, 2005.  The Partnership?s net asset value per Unit decreased
from $4,658.88 at December 31, 2004 to $3,912.52 at March 31,
2005.

The most significant trading losses of approximately 17.2% were
recorded in the currency sector throughout the quarter from
positions in a variety of foreign currencies versus the U.S.
dollar.  During January, long positions in a variety of foreign
currencies, primarily the euro, South African rand, Japanese yen,
and Swiss franc, recorded losses after the U.S. dollar?s value
reversed sharply higher amid conflicting economic data, positive
U.S. economic data, and speculation for higher U.S. interest
rates.  Finally, the U.S. dollar?s value also advanced during
January in response to expectations that the Chinese government
would announce postponement of its revaluation of the Chinese
yuan for the foreseeable future.  During February, long positions
in the Singapore dollar against the U.S. dollar experienced
losses as the U.S. dollar?s value rose in response to positive
sentiment for the Bush Administration?s budget proposal.  Relaxed
speculation that China would revalue its currency following the
Group of Seven (?G-7 countries?) meetings also boosted the U.S.
dollar.  The G-7 countries consist of France, the U.S., Britain,
Germany, Japan, Italy, and Canada.  Additional losses were
<page> recorded from established short positions in the Singapore
dollar, as well as from existing short positions in the euro,
Swiss franc, South African rand, and Norwegian krone against the
U.S. dollar as the U.S. dollar weakened due to concerns for the
considerable U.S. Current Account deficit as expressed by Federal
Reserve Chairman Alan Greenspan.  The U.S. dollar weakened
further during the remainder of the month due to a larger-than-
expected drop in economic indicators and news that South Korea?s
Central Bank planned to reduce its U.S. dollar currency reserves.
Short European currency positions resulted in losses during early
March as their values moved higher amid a sharp rise in German
industrial production.  Additional losses were recorded from
newly established long European currency positions, as well as
from existing long positions in the British pound and the
Singapore dollar, versus the U.S. dollar after the value of the
U.S. dollar reversed sharply higher amid an increase in U.S.
interest rates and consumer prices.  Additional Partnership
losses of approximately 2.7% established in the global interest
rate markets occurred primarily during February and March from
positions in Japanese and European interest rate futures.  During
February, long positions resulted in losses as prices reversed
lower after positive economic data and expectations for higher
interest rates reduced investor demand for fixed-income
investments.  Short positions held during March recorded losses
after prices reversed higher amid overall weakness in global
equity markets and the emergence of poor Japanese economic data
that signaled the potential for another recession.  Losses of
<page> approximately 1.3% resulted in the metals markets
throughout the quarter from positions in precious metals. During
January, long futures positions in gold and silver incurred
losses after prices declined due to reduced demand caused by U.S.
dollar strength.  Short futures positions in precious metals held
during February generated losses after prices advanced amid a
weaker U.S. dollar. During March, long futures positions in
precious metals experienced losses after prices declined amid
renewed strength in the U.S. dollar.  A portion of the
Partnership?s overall losses for the quarter was offset by gains
of approximately 4.1% recorded in the energy markets, primarily
during February and March, from long positions in crude oil and
its related products. Long futures positions benefited during
February after prices advanced following International Energy
Agency announcements concerning the potential for reduced supply
due to increased demand from China. Fears of terror attacks
against production facilities in the Middle East, cold weather in
the Northeastern U.S., and the perception that OPEC was intent on
maintaining higher price levels also boosted prices.  Long
positions continued to profit during March as prices were
bolstered after OPEC oil ministers stated there were no plans to
increase output. Also boosting prices was an Energy Information
Administration report alerting that U.S. inventories of gasoline
and heating oil measured significantly lower-than-expected.  The
weaker U.S. dollar also triggered crude oil demand early in the
month from countries such as Japan and China.  Finally, prices
soared at the end of March after Goldman Sachs analysts warned
<page> oil prices could reach $105 a barrel in the future.
Additional sector gains were achieved from long futures positions
in natural gas as prices advanced in tandem with crude oil
prices.  Gains of approximately 0.5% were recorded in the global
stock index markets, primarily during February, from long
positions in Pacific Rim and European equity index futures as
equity prices moved higher early in the month amid the successful
elections in Iraq and lower-than- expected U.S. unemployment
data.  Long positions in Pacific Rim equity index futures
continued to profit as prices drifted higher after positive
economic data reflected the potential for future economic growth
in the Far East.  Finally, stronger-than-expected growth in U.S.
Gross Domestic Product pushed global stocks higher as investors
welcomed the benefits of an improving global economy.  Additional
Partnership gains of approximately 0.5% were achieved in the
agricultural markets from long futures positions in coffee as
prices increased to five-year highs amid news of strong demand
and expectations for smaller near-term crops.  Speculative buying
and concerns for dry weather in Brazilian growing regions also
forced prices higher during March causing long positions to
profit further.

For the Quarter Ended March 31, 2004
The Partnership recorded total trading results including interest
income totaling $534,489 and expenses totaling $538,636,
resulting in a net loss of $4,147 for the quarter ended March 31,
<page> 2004.  The Partnership?s net asset value per Unit
decreased from $4,981.39 at December 31, 2003 to $4,977.27 at
March 31, 2004.

The most significant trading gains of approximately 3.3% were
recorded in the global interest rate markets.  Long positions in
U.S. and European interest rate futures benefited from the
January release of weak U.S. economic data and February comments
from global central banks regarding non-inflationary economic
environments.  Additional gains of approximately 2.5% were
recorded in the energy markets, primarily during February, from
long futures positions in crude oil and its related products as
low market supply, falling inventory levels, and production cut
announcements from OPEC caused prices to increase.  Profits of
approximately 2.5% were also achieved within the metals markets,
primarily from long futures positions in base metals, such as
copper, aluminum, and zinc.  Industrial metals prices rose higher
amid a declining U.S. dollar and increased demand from Asia.
During March, long futures positions in silver supplied gains as
prices for the precious metals trended consistently higher amid
central bank demand triggered by lower currency values.  In the
agricultural markets, gains of approximately 1.9% were generated
from long futures positions in corn, soybeans, and soybean
related products.  Growing U.S. exports and heightened demand
from Asia pushed prices for these commodities higher during the
<page> quarter.  A portion of the Partnership?s overall gains for
the quarter was offset by losses of approximately 9.8% incurred
in the currency markets from short positions in the Japanese yen,
South African rand, and euro versus the U.S. dollar. Short
Japanese yen positions experienced losses during March as the yen
reversed higher due to speculation that the Bank of Japan was
relaxing its efforts to weaken the yen.  Short euro positions
suffered losses also during March as expectations for an interest
rate reduction by the European Central Bank dissipated.  During
February, short positions in the South African rand produced
losses as the value of the rand reversed upwards following the
release of positive South African economic data.
<page> Item 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT
MARKET RISK

Introduction
The Partnership is a commodity pool engaged primarily in the
speculative trading of futures, forwards, and options.  The
market-sensitive instruments held by the Partnership are acquired
for speculative trading purposes only and, as a result, all or
substantially all of the Partnership?s assets are at risk of
trading loss.  Unlike an operating company, the risk of market-
sensitive instruments is inherent to the primary business activity
of the Partnership.

The futures, forwards, and options traded by the Partnership
involve varying degrees of related market risk.  Market risk is
often dependent upon changes in the level or volatility of
interest rates, exchange rates, and prices of financial
instruments and commodities, factors that result in frequent
changes in the fair value of the Partnership?s open positions,
and consequently in its earnings, whether realized or unrealized,
and cash flow.  Gains and losses on open positions of exchange-
traded futures, forwards, and options are settled daily through
variation margin.  Gains and losses on off-exchange-traded
forward currency contracts are settled upon termination of the
contract, however, the Partnership is required to meet margin
requirements equal to the net unrealized loss on open contracts
in the Partnership accounts with the counterparty, which is
accomplished by daily maintenance of the cash balance in a <page>
custody account held at Morgan Stanley DW for the benefit of MS &
Co.

The Partnership?s total market risk may increase or decrease as
it is influenced by a wide variety of factors, including, but not
limited to, the diversification among the Partnership?s open
positions, the volatility present within the markets, and the
liquidity of the markets.

The face value of the market sector instruments held by the
Partnership is typically many times the applicable margin
requirements.  Margin requirements generally range between 2% and
15% of contract face value.  Additionally, the use of leverage
causes the face value of the market sector instruments held by
the Partnership to typically be many times the total
capitalization of the Partnership.

The Partnership?s past performance is no guarantee of its future
results.  Any attempt to numerically quantify the Partnership?s
market risk is limited by the uncertainty of its speculative
trading.  The Partnership?s speculative trading and use of
leverage may cause future losses and volatility (i.e., ?risk of
ruin?) that far exceed the Partnership?s experience to date
under the ?Partnership?s Value at Risk in Different Market
Sectors? section and significantly exceed the Value at Risk
(?VaR?) tables disclosed.

<page> Limited partners will not be liable for losses exceeding
the current net asset value of their investment.

Quantifying the Partnership?s Trading Value at Risk
The following quantitative disclosures regarding the Partnership?s
market risk exposures contain ?forward-looking statements? within
the meaning of the safe harbor from civil liability provided for
such statements by the Private Securities Litigation Reform Act of
1995 (set forth in Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934).  All
quantitative disclosures in this section are deemed to be forward-
looking statements for purposes of the safe harbor, except for
statements of historical fact.

The Partnership accounts for open positions on the basis of mark
to market accounting principles.  Any loss in the market value of
the Partnership?s open positions is directly reflected in the
Partnership?s earnings and cash flow.

The Partnership?s risk exposure in the market sectors traded by
the Trading Managers is estimated below in terms of VaR. The
Partnership estimates VaR using a model based upon historical
simulation (with a confidence level of 99%) which involves
constructing a distribution of hypothetical daily changes in the
value of a trading portfolio.  The VaR model takes into account
linear exposures to risk including equity and commodity prices,
interest rates, foreign exchange rates, and correlation among
<page> these variables. The hypothetical changes in portfolio
value are based on daily percentage changes observed in key market
indices or other market factors (?market risk factors?) to which
the portfolio is sensitive.  The one-day 99% confidence level of
the Partnership?s VaR corresponds to the negative change in
portfolio value that, based on observed market risk factors, would
have been exceeded once in 100 trading days, or one day in 100.
VaR typically does not represent the worst case outcome.
Demeter uses approximately four years of daily market data (1,000
observations) and revalues its portfolio (using delta-gamma
approximations) for each of the historical market moves that
occurred over this time period.  This generates a probability
distribution of daily ?simulated profit and loss? outcomes.  The
VaR is the appropriate percentile of this distribution.  For
example, the 99% one-day VaR would represent the 10th worst
outcome from Demeter?s simulated profit and loss series.

The Partnership?s VaR computations are based on the risk
representation of the underlying benchmark for each instrument or
contract and do not distinguish between exchange and non-exchange
dealer-based instruments. They are also not based on exchange
and/or dealer-based maintenance margin requirements.

VaR models, including the Partnership?s, are continually evolving
as trading portfolios become more diverse and modeling techniques
and systems capabilities improve.  Please note that the VaR model
is used to numerically quantify market risk for historic <page>
reporting purposes only and is not utilized by either Demeter or
the Trading Managers in their daily risk management activities.
Please further note that VaR as described above may not be
comparable to similarly titled measures used by other entities.

The Partnership?s Value at Risk in Different Market Sectors
The following table indicates the VaR associated with the
Partnership?s open positions as a percentage of total net assets
by primary market risk category at March 31, 2005 and 2004.  At
March 31, 2005 and 2004, the Partnership?s total capitalization
was approximately $15 million and $22 million, respectively.

Primary Market		        March 31, 2005       March 31, 2004
Risk Category       	   Value at Risk        Value at Risk

Currency                       (2.93)%  	             (1.53)%
Equity                         (1.03)  	              (0.81)
Interest Rate                  (0.89)  	              (0.83)
Commodity                      (4.71)        	        (2.03)
Aggregate Value at Risk        (5.74)%               (2.37)%

The VaR for a market category represents the one-day downside
risk for the aggregate exposures associated with this market
category.  The Aggregate Value at Risk listed above represents
the VaR of the Partnership?s open positions across all the market
categories, and is less than the sum of the VaRs for all such
market categories due to the diversification benefit across asset
classes.
<page> Because the business of the Partnership is the speculative
trading of futures, forwards, and options, the composition of its
trading portfolio can change significantly over any given time
period, or even within a single trading day, which could
positively or negatively materially impact market risk as
measured by VaR.

The table below supplements the quarter-end VaR set forth above
by presenting the Partnership?s high, low, and average VaR, as a
percentage of total net assets for the four quarter-end reporting
periods from April 1, 2004 through March 31, 2005.

Primary Market Risk Category	High	   Low	     Average
Currency	(3.12)%	(1.28)%	(2.28)%

Equity	(1.03)	(0.73)	(0.94)

Interest Rate	(1.58)	(0.89)	(1.09)

Commodity	(4.71)	(1.62)	(3.16)

Aggregate Value at Risk	(5.74)%	(3.01)%	(4.34)%


Limitations on Value at Risk as an Assessment of Market Risk
VaR models permit estimation of a portfolio?s aggregate market
risk exposure, incorporating a range of varied market risks;
reflect risk reduction due to portfolio diversification or hedging
activities; and can cover a wide range of portfolio assets.
However, VaR risk measures should be viewed in light of the
methodology?s limitations, which include, but may not be limited
to the following:
<page>
*	past changes in market risk factors will not always result in
accurate predictions of the distributions and correlations of
future market movements;
*	changes in portfolio value caused by market movements may
differ from those of the VaR model;
*	VaR results reflect past market fluctuations applied to current
trading positions while future risk depends on future
positions;
*	VaR using a one-day time horizon does not fully capture the
market risk of positions that cannot be liquidated or hedged
within one day; and
*	the historical market risk factor data used for VaR estimation
may provide only limited insight into losses that could be
incurred under certain unusual market movements.

In addition, the VaR tables above, as well as the past performance
of the Partnership, give no indication of the Partnership?s
potential ?risk of ruin?.

The VaR tables provided present the results of the Partnership?s
VaR for each of the Partnership?s market risk exposures and on an
aggregate basis at March 31, 2005, and for the four quarter-end
reporting periods from April 1, 2004 through March 31, 2005.  VaR
is not necessarily representative of the Partnership?s historic
risk, nor should it be used to predict the Partnership?s future
<page> financial performance or its ability to manage or monitor
risk.  There can be no assurance that the Partnership?s actual
losses on a particular day will not exceed the VaR amounts
indicated above or that such losses will not occur more than once
in 100 trading days.

Non-Trading Risk
The Partnership has non-trading market risk on its foreign cash
balances.  These balances and any market risk they may represent
are immaterial.

The Partnership also maintains a substantial portion
(approximately 92% as of March 31, 2005) of its available assets
in cash at Morgan Stanley DW. A decline in short-term interest
rates would result in a decline in the Partnership?s cash
management income. This cash flow risk is not considered to be
material.

Materiality, as used throughout this section, is based on an
assessment of reasonably possible market movements and any
associated potential losses, taking into account the leverage,
optionality and multiplier features of the Partnership?s market-
sensitive instruments, in relation to the Partnership?s net
assets.



<page>
Qualitative Disclosures Regarding Primary Trading Risk Exposures
The following qualitative disclosures regarding the Partnership?s
market risk exposures - except for (A) those disclosures that are
statements of historical fact and (B) the descriptions of how the
Partnership manages its primary market risk exposures - constitute
forward-looking statements within the meaning of Section 27A of
the Securities Act and Section 21E of the Securities Exchange Act.
The Partnership?s primary market risk exposures, as well as the
strategies used and to be used by Demeter and the Trading Managers
for managing such exposures, are subject to numerous
uncertainties, contingencies and risks, any one of which could
cause the actual results of the Partnership?s risk controls to
differ materially from the objectives of such strategies.
Government interventions, defaults and expropriations, illiquid
markets, the emergence of dominant fundamental factors, political
upheavals, changes in historical price relationships, an influx of
new market participants, increased regulation, and many other
factors could result in material losses, as well as in material
changes to the risk exposures and the risk management strategies
of the Partnership.  Investors must be prepared to lose all or
substantially all of their investment in the Partnership.

The following were the primary trading risk exposures of the
Partnership at March 31, 2005, by market sector.  It may be
anticipated, however, that these market exposures will vary
materially over time.
<page>
Currency.  The primary market exposure of the Partnership at March
31, 2005 was to the currency sector.  The Partnership?s currency
exposure is to exchange rate fluctuations, primarily fluctuations
which disrupt the historical pricing relationships between
different currencies and currency pairs.  Interest rate changes,
as well as political and general economic conditions influence
these fluctuations. The Partnership?s primary exposure at March
31, 2005 was to outright U.S. dollar positions.  Outright
positions consist of the U.S. dollar vs. other currencies.  These
other currencies include major and minor currencies.  Demeter does
not anticipate that the risk associated with the Partnership?s
currency trades will change significantly in the future.

Equity.  At March 31, 2005, the Partnership had market exposure to
equity sector.  Exposure was to equity price risk in the G-7
countries.  The stock index futures traded by the Partnership are
by law limited to futures on broadly-based indices.  At March 31,
2005, the Partnership?s primary exposures were to the NASDAQ 100
(U.S.), Euro Stoxx 50 (Europe), and DAX (Germany) stock indices.
The Partnership is primarily exposed to the risk of adverse price
trends or static markets in the U.S. and European stock indices.
Static markets would not cause major market changes, but would
make it difficult for the Partnership to avoid trendless price
movements, resulting in numerous small losses.

<page> Interest Rate.  At March 31, 2005, the Partnership had
market exposure to the global interest sector.  Exposure was
primarily spread across the Japanese, U.S., and European interest
rate sectors.  Interest rate movements directly affect the price
of the sovereign bond futures positions held by the Partnership
and indirectly affect the value of its stock index and currency
positions.  Interest rate movements in one country, as well as
relative interest rate movements between countries, materially
impact the Partnership?s profitability.  The Partnership?s primary
interest rate exposure is generally to interest rate fluctuations
in the U.S. and the other G-7 countries.  However, the Partnership
also takes futures positions in the government debt of smaller
countries - e.g., Australia.  Demeter anticipates that the G-7
countries and Australian interest rates will remain the primary
interest rate exposures of the Partnership for the foreseeable
future.  The speculative futures positions held by the Partnership
may range from short to long-term instruments.  Consequently,
changes in short, medium, or long-term interest rates may have an
effect on the Partnership.

Commodity.
Energy.  The second largest market exposure of the
Partnership at March 31, 2005 was to the energy sector.
Exposure was primarily to futures contracts in crude oil and
its related products, and natural gas.  Price movements in
these markets result from geopolitical developments,
particularly in the Middle East, as well as weather patterns
<page> and other economic fundamentals.  Significant profits
and losses, which have been experienced in the past, are
expected to continue to be experienced in the future.
Natural gas has exhibited volatility in price resulting from
weather patterns and supply and demand factors and will
likely continue in this choppy pattern.

Metals.  At March 31, 2005, the Partnership had market
exposure in the metals sector.  Exposure was to fluctuations
in the price of base metals, such as copper, nickel,
aluminum, and zinc, and precious metals, such as gold and
silver.  Economic forces, supply and demand inequalities,
geopolitical factors, and market expectations influence price
movements in these markets.  The Trading Managers utilize the
trading system(s) to take positions when market opportunities
develop, and Demeter anticipates that the Partnership will
continue to do so.

Soft Commodities and Agriculturals.  At March 31, 2005, the
Partnership had market exposure to the markets that comprise
these sectors.  Most of the exposure was to the cotton,
sugar, coffee, cocoa, and corn markets.  Supply and demand
inequalities, severe weather disruptions and market
expectations affect price movements in these markets.

<page>
Qualitative Disclosures Regarding Non-Trading Risk Exposure
The following was the only non-trading risk exposure of the
Partnership at March 31, 2005:


Foreign Currency Balances.  The Partnership?s primary foreign
currency balances at March 31, 2005 were in Hong Kong
dollars, Japanese yen, euros, and British pounds.  The
Partnership controls the non-trading risk of foreign currency
balances by regularly converting them back into U.S. dollars
upon liquidation of their respective positions.

Qualitative Disclosures Regarding Means of Managing Risk Exposure
The Partnership and the Trading Managers, separately, attempt to
manage the risk of the Partnership?s open positions in essentially
the same manner in all market categories traded. Demeter attempts
to manage market exposure by diversifying the Partnership?s assets
among different Trading Managers in a multi-manager Partnership,
each of whose strategies focus on different market sectors and
trading approaches, and by monitoring the performance of the
Trading Managers daily. In addition, the Trading Managers
establish diversification guidelines, often set in terms of the
maximum margin to be committed to positions in any one market
sector or market-sensitive instrument.

<page> Demeter monitors and controls the risk of the Partnership?s
non-trading instrument, cash.  Cash is the only Partnership
investment directed by Demeter, rather than the Trading Managers.

Item 4.	CONTROLS AND PROCEDURES
   (a)	As of the end of the period covered by this quarterly
report, the President and Chief Financial Officer of
Demeter, the general partner of the Partnership, have
evaluated the effectiveness of the Partnership?s
disclosure controls and procedures (as defined in Rules
13a-15(e) and 15d-15(e) of the Exchange Act), and have
judged such controls and procedures to be effective.

 (b)	There have been no material changes during the period
covered by this quarterly report in the Partnership?s
internal controls or in other factors that could
significantly affect these controls subsequent to the date
of their evaluation.
