light audited from No. 4 ash tail burner wee equal
to 9.1 war candles and 7.9 sperm. 3rd. That furnished by
the bat-wing was of the mean intensity of 8.7 wax candles
and 7.1 sperm. These results show that the average illu-
minating power of the gas supplied by the company daring
the last quarter has been fully one-foorth snore than that
required by the act of parliament. In my former report I
stated that the mean illuminating power of the gas for the
quarter ending in May last was as great as that furnished
by 17 wax candles, each of 120 grains per hour. Now ea
this stateusent may possibly lead to the conclusion that
there has been a falling off in the mean luminosity of the
gas during the last three months, I beg to remark that the
difference of my results now and then has arisen not eo
mush from inferiority in the quality of the gas, OA from the
einonastance that I have lately adopted a more rigorous
mode of investigation—as by testing the illuminating powers
of none but the direct rs from the burner and candle.
This method was suggested to me by Mr. Barlow, who
Is the editor of the " Journal of Gas Lighting," and
it was, I believe, originally contrived by Mr. Lowe Thomp-
son. It consists in the employment of an apparatus which
completely shuts out from the pholometer all the rays of
light but those proceeding directly from the illuminating
agents. I am aware that objections may be raised by gas
manufacturers to this contrivance, on the ground that it
does not fairly represent the conditirn under which gas is
usually employed as /t, source of light ; but I am satisfied
that the inatrumeshiie a very delicate one, and that it is
consiructed on pineiples which are strictly correct. I shall,
therefore, continue to use it until a better pholometer is
invented...Fiselly, I beg to state that I havo found the
gravity of the gas to range between 404 and 426.
number, represent the density of the gee at a tem-
perature of 60 dep. of Fahrenheit, end a pressure of 29 dep.
of the barometer. They indicate, when placed in opposi-
tion with the results obtained with the pholonater, that tho
gas is of good illuminating power, and that it is rich in the
denser hydro-carbons. "
The report, which is signed H. Letheby, M. 8., London
Hospital, concludes with recommending to all gar com-
panies to get rid of certain impurities in the manufacture,
and that every attention should be paid to ventilation so as
to carry off the noxious products generated during ita
combustion. _ .

The report was ordered unanimously to be entered on the
journals.

WATER SUPPLY.

An important report on the subject of the supply of
water to the City was presented by the surveyor to the
comrniaaionen, and ordered to be printed and taken into
consideration on a future day.
it was referred to a committee to inquire auto the pro-
priety of obtaining fur the surveyor large and commodores
offices, and adapted to the vast increase of the business of
the commissioners of the City Sewers.
The court then adjourned.
