![IB Public Analyst’s Laboratory, 67, Surrey Street, Sheffield. REPORT ON A SAMPLE OF DRINKING WATER. Received from the Corporation of the Borough of Rotherham, on February 7th, 1895. Sample Mark, 77. Physical Characters: Suspended Matter, none. Appearance of a Column two feet long, clear and pale yellow. Taste, normal. | Odour, none. On Analysis, the sample gave the following results. :— Total Solid Matter, 24-61 grains per gallon ; which lost on Ignition, P12 grains. Chlorine, 2*10 grains per gallon ; equal to Sodium Chloride, 3-47 grains. Nitrogen in oxidised forms, trace; equal to Nitric Acid (anhy¬ drous), trace. Poisonous Metal (Lead, &c.), none. Degrees of Hardness, 16’0 [Each degree of hardness represents a soap destroying power equivalent to one grain of chalk per gallon.] Reducing Power, P20 parts per million. [Representing the Oxygen absorbed by the organic and other oxidisable matters in one million parts of water.] Free and Ureal Ammonia, 0*05 parts per million. Albuminoid Ammonia.0T6 ,, ,, These results are not wholly satisfactory. The figures recorded under the heads of “ reducing power” and “ album¬ inoid ammonia ” point to the existence of traces of readily changeable organic matter. The origin of this is uncertain, but probably vegetable or the result of the infiltration of drainage from cultivated land. ALFRED H. ALLEN. February 23rd, 1895.
