SANITARY WORKS.
Tables are appended, as usual, kindly furnished, the one by Mr.
Worrell, Chief Clerk in the Department of Works; the other by
Mr. Leach, Clerk in the Sanitary Department, assisted by the
Sanitary Inspectors, giving details as to the amount of Sewer work
done, nuisances abated, unsound food seized, &c., during the past
year.
I desire to acknowledge the cordial manner in which the officers
in the Sanitary Department have assisted me in carrying out my
duties during the year under notice.
GAS.
The average illuminating power of the Gas supplied by the
Imperial Company, as tested by Letheby's photometer, according to
the requirements of the Metropolis Gas Act, 1860, was 14.4 standard
sperm candles. The highest illuminating power observed was 16.4
candles, and the lowest 12.6 candles.
The average illuminating power was a trifle less than during the
preceding year, and the fluctuations were greater; the maximum
illuminating power observed being greater, and the minimum less
in 1872 than in 1871.
Sulphur in various forms fluctuated from 18.4 to 39.9 grains per
100 cubic feet; the average amount present having been 24.5 grams.
During the previous year (1871) the amount was less and the fluctuations
not so great. Ammonia was invariably present though never
in excessive quantities. Sulphuretted hydrogen was never detected
in the Gas supplied at the testing station, 10, Edward Street.
On the whole, the Gas supplied in 1872 was not quite so good as
during 1871; but the inferiority was only slight. It is to be feared
that with the continued high price of coals, but little improvement
in the quality of the Gas can be expected.
