PRICE and PURIFICAT :lON of GAS:'3I.

Yesterday a special meeting of the C,.linniissionera
of Sewera for the city of London took pt:ace at the
Guildhall, upon the references to inquire Into the
price of gas generally, and also for the purpwe of
receiving important information from Mr. Leslie, one
of the members of the Metropolitan Sanitary Com-
mission, who had consented to attend the board in
order to communicate to them the nature of the
improvements which were taking place under his
superintendence in several of the departments of the 7.
Government. Deputy Peacock in the chair. '`rf_fi,
In answer to a question from Mr. LESLIE,
Mr. DAw, the chief clerk to the Commissioners,
said the City consumption of gas in the public lamps
cost between 11,0001.. and 12,0001. a year, and that
the gas supplied to the prisons of Newgate, Giltspur-
street, Whitecross-street, and Bridewell, was not
included in that charge, the expenditure of the article
in these places being defrayed by the City under the
head of pavinga a

heath, by taking out all its impuri-
ties. The first public exiTriment made by him as to
ust o
heftthe illumination, had been ethSted under the authority
of the Commissioners of Woods and Forests, in the
Queen's-walk, in the Green-park, where he had fixed
his burners to IS of the lamps, which were 90 feet
apart, and consumed 4f feet per lamp per hour.
The contrast between these lamps and the others
lighted upon the usual plan, was most palpable. It
was only necessary for the Commissioners to trust to
their own eyes. The next experiment was made by
him at the Post-office, perhaps the largest affair of
the kind in the world. His burners were as yet but
partially in operation in that establishment, but they
would completely supersede the old system is a very
short time.
.Mr. LAWRENCE asked whether the gas consumed
in the Post-office was purified, and what might be
the sanitary effect of the purification ?
Mr. LESLIE said that nearly all the offices in the
establishment were lighted by his apparatus for
purifying as well as illunjnating, and, as to sanitary
results, there was not the

plan would amount, per week, to at least .54,0" feet,„,
and yet he found that throughout the vario.."
partments there was too much gas. The illutnirt:l°a
was powerful, and there was no smell—two effects, co.
which many persons who were capable of seeing and
smelling could adequately judge.
Mr. LAWRENCE—You consider that we could, by
your process, light the streets of the City at 24 per
cent. less charge than we now pay ?
Mr. LESLIE said, considerably more; and at the`
close of the meeting he stated that the saving wouldl
be more likely to be 50 per cent. than 25 per cent.
A street lamp should burn 3,480 feet per annum, And.
he would produce as good a light, by the application
of his burners to the public lamps, as those at present
exhibited, at less than three-fourths of the quantity of
gas. For the purification of the gas—which purifica-
tion would, there could not exist a doubt, be required
universally in a short time—he should require to fix
the apparatus in the company's premises ; but as re-
garded the combustion, his burners alone would be
calculated to effect the necessary improvement in the
quality.
In answer to questions from Mr. Morrison and
other members of the board, Mr. LESLIE gave a
scientific description of his mode of accurately testing
the exact amount of light in which his process differed
from that to which we have been long accustomed.
For his burners his charge was seven shilling each,
the sum paid by the Government, the parish of St.
James's, and in fact by all parties who had determined
to adopt his process, after having seen the results of
the experiments which had been made.
Mr. LAWRENCE asked what Mr. Leslie thought
the Commissioners of Sewers ought to be able, on an
average, to make and supply gas for to the public, if
they made it themselves ?
Mr. LESLIE answered—Three shillings for every
1,000 cubic feet, and that charge would include
every cost of plant, mains, Sze. The materiels he
used in the process of purification absorbed all tie.
deleterious and offensive parts of the gas.
A MEMBER OF TBE BOARD—WouId the deposit
be valuable after the purification takes place ?
Mr. LESLlE—Certainly, to a considerable amount.
Mr. HARRISON—Cnn you, without purifying, lower
the price of illuminating
Mr. LESLIE—Yes. But purification must be
adopted. The benefits of purification are so great
that it is quite impossii3le to argue upon the continu-
ance of the impure state of the article in any case. If
you have 2,700 public lamps in the City, that number
would demand a supply of 13,500 feet per hour for
the whole. Your gasometers, two of which you
should have, and that number would be sufficient for
you, should have in each of them six hours' stock of
gas. A space of forty feet diameter would be suffi-
cient to build them in. The purification would render
the glasses much less liable to damage. In fact, by-
and-by purification will be the indispensable attendant
of illumination by gas.
The CHAIRMAN—Are the two companies, the
Chartered Gas and the City Gas Companies, who
supply us aware of these facts which you have stated
to us ?

Dlr. LESLIE—Yes, as well as I am.
LAWEENCE—Are they aware of these effects
which you have stated to us ?

Ali EAST DEATH FOR PORKRES.—Judging from
the noise they make, pigs have no particular pellebint

is a nuisance to all concerned and to all the neighbour-
hood. It appears that henceforth the swinish multitude
may be enabled to die with more dignity and decorum,
and this by means of the new anzesthetic agent, chloro-
form. The Ragas Guardian thuS decribes the first
instance on record of a pig's dying, morspatriums without
making any fuss about it:—" Christmas is a fatal period
for pigs, and right glad no doubt would the majority of
the ' grunt creation' be to quit existence upon more
agreeable terms. Well, thanks to the invention of the
age, a more desirable transit into nonentity has been
effected, for the other day, Mr. Horace Watson, druggist,
