No. 7. The Colonial Analyst, Christchurch, to the Undee Secbetaey. Sic, — Canterbury College Laboratory, 11th September, 1879. I beg to acknowledge the receipt of your favour No. 1,224, of the Ist instant (addressed in error to Professor Brown), and in reply to inform you that, out of thirty-six analyses made on waters from different parts of Canterbury, only one example of mineral waters has come under my notice, on which I enclose a report. As an example of the great purity of the waters here generally, I may mention that I have recently analyzed the water supplies of Rangiora and Christchurch, and the results obtained prove them to be amongst the purest natural waters in the world. Should Ibe able to procure any further information on this subject, I will communicate with you. I have, &c., A. W. Bickeeton, Colonial Analyst. Quantitative Results of an analysis of chalybeate waters received from Mr. G. M. Douglas, Amberley: — Grains per gallon. Total dissolved solids ... ... ... ... ... 376 Volatile ... ... ... ... ... ... 8-8 Fixed ... ... ... ... ... ... 288 Carbonate of lime ... ... ... ... ... 36 Carbonate of magnesia ... ... ... ... ... 22 Chlorine ... ... ... ... ... ... 100 Iron protoxide ... ... ... ... ... 23 Free ammonia ... ... ... ... ... -069 Albuminoid ammonia ... ... ... ... ... -034 Sediment ... ... ... ... ... ... 1652 The above analysis proves this sample of water to contain a considerable amount of protosalts of iron, sufficient to entitle it to the designation of a chalybeate water. The amount of organic matter present, however, renders it quite unfit for drinking purposes. Could this water be obtained free from its organic impurities, it would probably be of considerable value as a mineral water. A. W. BICKEETON, Canterbury College Laboratory, 17th June, 1879. Analyst.
