![Public Analyst’s Laboratory, 67, Surry Strfet, Sheffield. Report on a Sample of Drinking Water, received from the Rotherham Corporation, on March 28th, 1899. Sample Mark :—“ No 97.” Town Supply. Physical Characters Suspended Matter, None. Appearance of a Column two feet long, Clear & Colourless Taste, Normal. Odour, None. On Analysis, the sample gave the following results :— fToTAL Solid Matter, 21-28; which lost on Ignition, £ _ | 5-60 grs. J Chlorine, 1-90; equal to Sodium Chloride, 313 grs. || j Nitrogen in oxidised forms, 0-47; equal to Nitric Acid o ; (anhydrous) 1*81 grs. ^Poisonous Metals (Lead &c.) None. Degree of Hardness, 12*0. [Bach degree of hardness represents a soap-destroying power equivalent to one grain of chalk per gallon.] Reducing Power, 032. [Representing the Oxygen absorbed by the organic and other oxidisable matters in one million parts of water.] Free and Ureal Ammonia, 0 03 parts per million. Albuminoid Ammonia, 0‘06 parts per million. The presence of nitrates suggests that the water has received an infiltration of drainage of some sort, possibly the drainage from cultivated land. The figures under the head of Free and Albuminoid Ammonia show that the water in its present condition is free from other than normal traces of readily-changeable organic matter. ALFRED H. ALLEN.
