the cannel gas of the Chartered Company also presented a trace
of ammonia.
The following Table gives the average light in sperm candles of all the gases—
| Chartered. | London. | Equitable. | |
|---|---|---|---|
| Cannel | 24.38 | 23.88 | 26.07 |
| Common | 14.31 | 14.31 | 14.58 |
On May the 26th, I made some experiments on the common
gas, at the testing room of the Equitable Gas Company,
between the "Birmingham " burner, No. 1; Sugg's burner,
No. 2, used by the Gas Companies; and the old iron burner,
No. 3, employed by the public. The average light of
No. 1 equalled that of 13.07 sperm candles
No. 2 „ „ 14.21 „
No. 3 „ „ 12.36 „
the difference therefore between
No. 1 and No. 3 equalled .71 sperm candles, and between
No. 2 and No. 3 „ 1.85 „
or 14.96 per cent. in favour of the burner used by the Companies
as against that used by the public. I was requested
to make these experiments in consequence of the recent opposition
to the Birmingham and Staffordshire Gas Bill in the
House of Commons, which ended in a compromise with the
following results:
1. No notice of examination of the gas was to be
given to the Company.
2. The adoption of the system of meter for public
lights.
3. The burner, used by the Company, to be
posited.
A Table and Summary were sent with each Monthly
Report on the gas to the Vestry, containing the number of
examinations and the pressures, with the dates, and the
weekly and monthly average illuminating power.
