It appears from these results, that the average illuminating
power of the gas, at the station, was higher than
the Parliamentary standard, and that, excepting on one
occasion, the minimum was equal to or above the requirement.
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. 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 which was more
than maintained in 1892.
