APPENDIX.
The illuminating power of the Gas supplied to the
Workhouse at Mount Street, according to observations
made during August and September 1859, was such, that
2*5 feet burned in a batswing burner, gave a light equal
to that of 13'9 sperm candles, burning 120 grains per
hour. No sulphuretted hydrogen was detected.
During July the apparatus was dismantled, that the
meter might be examined and tested.
The illuminating power of the Gas* supplied to the
room in West Basin Road during the same period, when
burned in a batswing burner, gave an average result
equal to that of 9.9 sperm candles, burning at the above
rate ; and no sulphuretted hydrogen was discovered.
* In consequence of a strike among the workmen, there was a considerable
diminution of illuminating power for several nights early in
August, and on Tuesday night, September 20, the out-wards were almost
in total darkness, arising, as alleged, from an obstruction in the hydraulic
main, where one bed of pipes was supplying cannel gas.
