Gas.
One hundred and ninety-five observations were made
during the year upon the four gases supplied by the
London and Equitable Companies, at No. 73, Bessboroughstreet
and Cambridge-street respectively.
The gases were burned in accordance with the Metropolis
Gas Act, 1860, and the illuminating power continued
above the standard required by the Act.
With respect to purity all the gases were free from
sulphuretted hydrogen, and so far free from ammonia that
they did not discolour the turmeric paper, except on April
13th, 20th, May 12th, 18th, 26th, June 3rd, 7th, 24th,
July 21st, August 9th, 1870, and February 22nd and
March 22nd, 1871, when the common gas of the London
Company presented traces of ammonia.

The following table gives the average light monthly in sperm candles of all the gases:—

A table and summary were sent with each Monthly
Report on the gas to the Vestry, containing the number
of the examinations and the pressures, with the dates, and
the weekly and monthly average illuminating power.
I remain,
My Lords and Gentlemen,
Your faithful Servant,
C. J. B. ALDIS, M.D.,
