Sample Mark :—“ Town Supply, No. 88.” Physical Characters Suspended Matter, trace. Appearance of a Column two feet long, clear and colourless. Taste, normal. Odour, none. On Analysis, the sample gave the following results :— u <D . a co O G=! •r) aJ 2 O N Total Solid Matter, 25*56; whichioston Ignition, 4-20 g. Chlorine, 1*75 ; equal to Sodium Chloride, 2-88 grs. -Nitrogen in oxidised forms, 0*40 ; equal to Nitric Acid (anhydrous), T54. , Poisonous Metals (Lead, &c.), none. Degrees of Hardness, 15-0. [Each degree of hardness represents a soap-destroying power equivalent to one grain of chalk per gallon.] ! Reducing Power, 0-08. [Representing the Oxygen I absorbed by the organic and other oxidisable matters £]§ t in one million parts of water.] £ a ! Free and Ureal Ammonia, 0-05 parts per million. / Albuminoid Ammonia, 0*08 parts per million. These results show the water to be satisfactorily free from readily changeable organic matter. The presence of oxydised compounds of nitrogen is probably attributable to the water receiving the drainage from cultivated land. March 12th, 1897. ALFRED H.
