GAS.
The subjoined Tables, based on the quarterly reports of
the Chief Gas Examiner, summarize the principal results
(averages) of the daily testings, at the Ladbroke Grove Station,
of the " common gas," manufactured by the Gas Light and Coke
Company at their Kensal Green Works.
1. With respect to illuminating power. The maximum, minimum, and average illuminating power, in standard sperm candles, the statutory standard being 1(3 candles, was as follows:—
| Maximum. | Minimum. | Average. | |
|---|---|---|---|
| Quarter ended March 31st | 17.8 | 16.0 | 16.7 |
| Quarter ended June 30th | 22.2 | 15.8 | 17.7 |

| Quarter ended December 31st | 17.1 | 16.1 | 16.5 |
| Averages, whole year | 19.3 | 16.4 | 17.2 |
It appears from these results that the average illuminating
power of the gas at the Station was higher than the Parliamentary
standard. On one occasion only was the minimum lighting
power lower than the Parliamentary standard, viz. 15.8 on
May 24th.
In the Annual Report of the late Metropolitan Board
of Works for 1884, it was stated—as the result of testing
with a portable photometer—that there are parts of London the
inhabitants of which do not always get their gas of the quality
which it was thought had been secured to them by Act of
Parliament; the gas hiving been frequently found to be inferior
in lighting power to the prescribed standard, sometimes by as
much as one candle, There is no way of preventing this, the
companies in default being subject to no forfeiture or penalty,
as they are when the gas is shown to be defective at the regular
testing places- The above facts point to the necessity for an
