may not snnaturslly put many of their guard Il is
necssssTy, therefore, TO remind all these whe may
have fancy for taking shares, that overy account
hitherto reo~ived from Cslifornis has established
the fact, that not a single instance has yet been
known where miners have continued 70 work az a
partnership body, when the total profits were to
be fully divided amongst them 80 that theprospect OF
working in order that the results Of their labor
may be transmitted to Shareholders in England may
easily be estimated. In case, however, this fact,
coupled with the style OF Mr.. Palmcrs reports, and
the questionable circumstances connected with the
issue Of the former prospectus, should not be enough
to excite caution, il may be as well TO mention,
that the only known city name in the published
prospectus Of the company, 10 that of Messrs
SpoOper, Atwoods, and Company, who are made to
figure as its bankers, and that this firm, upon aP-
plication being made to them, state that the COM
psny have no account with them. and have never
had authority TO use their names.
New Inventions for Lighting and Heating.

The patextee's inve~tiom consists in certoim apps-
rates o~d processes for producing hydrogen gas, by
the decomposition 0f u0ter, and tts dppfoGtton to
heat a~d light. The means and processes by which
he obtains this gas First-By the incsleseence
(ncende scence) OF iron.
Secondly-By carbon.
ThiTdly-By magnets.

In retorts purposely constructed, and fitted up with
iron tubes (enclosed in iron plates) or with iron
chains, iron wire, or spiras of the same metal rem
dered iDcalescent, the pstentee introduces steam
from any generator whatever-or he even produ-
ces steam by means Of water injected into tho
retor. The oxygen of the water combines with
the iron, and the hydrogen Is conducted first into
refngerant, and thence into a gasometer, from
which ii is supplied for use. When the iron is

OF the waste gas Of furnaces the carbonc acid of
the furnaces il at first changed into oxide of carbon
within the furnace in which the hydrogen, az well
as the oxide Of carbon is Produced the last gas is
obtained by the passage OF steam into tho oxide fur
mace q kind Of kiln); the oxide Of carbon and
hydrogen are afterwards injected into the retort
containing the oxidzed iron; this latter transmits
the oxygen to the oxide Of carbon, and to the hy-
drogen which has been generated in the furnace for
oxide Of carbon.
Secondly-The patentee dis-oxidizes iron by
causing to fall on incalescent iron, some pulver-
ized coal, coke, charcoal, pt-coal, ligneous sub
stances, &o.; also BY ignting with oxide Of iron
some hydrogen, oxide Of carbon, or by throwing on
the incalescent iron some oil or any of the hydro
caIbuietseyen tar or ammoniacal waters.
Thirdly-The patentee dis-oxidizes iron by sub
mitting it to white heat, when this metal loses
its oxygen like peroxide Of manganese and returns
to the state Of protoxide Of iron, by which means
the water il decomposed.

1g~so~s sbstamcss or ca,6oxi.sd pit (peai,) or by

steam TO pass into horizontal ret similar those
employed in gas works, filled up more or less with
deep layers Of coal the steam s distributed to the
whole OF the retors, and over the surface Of the
Goals by means Of one or more pipes in connection
with boiler, pierced with hees Of a small dame
ter, like the spout Of waterpot the contact of the
steam produces hydrogen, carbonic acid, and
small quantity OF oxide Of carbon and other gases ;
these mixed gases pass OIL through the educt pipe

up, and the hydrogen passes of into the gas
for decomposing water is similar to that in which
coal s distilled, differing, however, from il, re-
CARDS the steam tubes, the boiler, and the system
depostng the steam on the surface Of the Goals,
instead OF passing il through them these points the
paentee states TO be new. The pafsxtee also de-

The patentee's improved process for rendering
hydrogen gas Illuminating. is BY causing small
jet of lighted hydrogen to pass through a burner
(the holes very smalD on a thin strip Of platinum,
or wick Of platinum wire, the threads being
cesevely fine, and OF graduated section. propor-
tened 10 the intensity or the pressure ofthe flame and
the burning hydrogen-a very powerful light is thus
produced. The platinum threads are imme diately
heated TO such whteness that the luminous re-
fulgence is extraordinarily brilliant. Besides pls
tinum, other unaterable and unoxidi1able metals
may be employed. The wick must be Of the shape
necessary 10 agree with that OF the jet Of hydrogen
IL may be that OF cone, or any other figure, accord
ing 10 the size INCH the gas takes when is allowed
egress from the burner the wick must be made
more or less strong, according to the greater or
less intensity Of the heat TO which it is exposed.
The burner and wick may be modified in their
shape-the patentee does not limit himself as re-
gards the strength, the length the height OF the
wick, provided the principle Of his invention be re-
tanned.

well for pig iron as for steel. The same here
inbefore described process is equally sp-
plicsble TO reverbcratory furnaces, and for
heating boilers and locomotives. The patentee
heats boilers and locomotives by hydrogen and
oxide Of carbon injected under the boilers in the
locomotives with hot or cold air, by means Of many
email holes or divided and conceniric tubes set
under the boilers, and he also njects hydrogen and
oxide Of carbon into the tubes Of tubular boilers,
by employing concentric tribes, in which the air
and gases Of the tenders, which are purposey con-
structed AZ reservoirs-are made to enter. The
pat,ntee constructs gas burners with double cur
rents Of air. that s TO say, the air acting internally
and externally on the flame; these burners have the
advantage ofprssenting large quantity Of air or OF
oxygen TO the combustion of the gas The paten-
tee does not ccpfne hmsef to the precise details
