maximum, moreover, not having been attained on any
occasion. The maximum, the minimum, and the average
amounts found in 1890, considerably exceeded the proportions
in 1889, as these exceeded those found in 1888. In 1891
there was an improvement in these respects.
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:—

Ammonia, a valuable residual product of gas manufacture,
was present in the gas more or less frequently

occasion was the limit fixed by the Acts of Parliament—
viz., 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.
