2. As regards Purity. The gas was free from sulphuretted
hydrogen throughout the year ; and the quarterly
average quantity of other sulphur compounds present in the
gas, was considerably less than the quantity permitted ; the
maximum, moreover, not having been attained on any
occasion.
Grains of sulphur per 100 cubic feet of gas; the Parliamentary limit being 17 grains in 100 cubic feet during the months from April to October, and 22 grains from October to April:—
| Maximum. | Minimum. | Average. | |
|---|---|---|---|
| Quarter ended March 31st | 11.8 | 8.0 | 9.5 |
| Quarter ended June 30th | 12.6 | 8.4 | 10.0 |
| Quarter ended September 30th | 15.8 | 5.1 | 9.4 |
| Quarter ended December 31st | 11.3 | 7.6 | 9.4 |
| Averages, whole year | 12.9 | 7.3 | 9.6 |
| Averages, 1892 | 13.6 | 8.9 | 10.6 |
| Averages, 1891 | 15.4 | 9.4 | 12.0 |
| Averages, 1890 | 16.0 | 10.7 | 13.1 |
| Averages, 1889 | 14.0 | 9.3 | 11.0 |
| Averages, 1888 | 12.7 | 7.8 | 9.7 |
Ammonia, a valuable residual product of gas manufacture,
was present in the gas more or less frequently throughout the
year, but only in slight quantities. On no occasion was the
limit fixed by the Acts of Parliament, four grains in 100 feet
of gas, exceeded.
The Chief Gas Examiner being independent of the Company,
it is satisfactory to note that his reports on the daily
testing of the gas are so favourable.
