GAS.
Eighty observations were made during the quarter
upon the six gases supplied by the Chartered, London, and
Equitable Companies, at the Works in Horseferry-road,
73 Bessborough-street, 78 Cambridge-street, and No. 1
Ebury Bridge-road respectively.
The gases were burned in accordance with the Metropolis
Gas Act, 1860, and the illuminating power continued
above the standard light, except on April 24th, when the
cannel gas from the London Company gave a light equal
to 17.6 7 instead of 20 sperm candles.
With regard to the purity of the gases, they were free
from sulphuretted hydrogen, and so far free from ammonia
that they did not discolour the turmeric paper.

The following Table gives the average light in sperm candles of all the gases.
