Excerpt from Potable Water: How to Form a Judgment on the Suitableness of Water for Drinking Purposes, Addressed to Medical Officers of Health, and Sanitary Authorities, Etc Since the publication of the first edition, the views I have ventured to put forward, as to the fallacy of judging chiefly of the wholesomeness of drinking water by the amount of organic matter it may contain, have received unexpected confirmation from no less an authority than Prof. Huxley, who, at a discussion at a recent meeting of the Chemical Society, gave it as his opinion, speaking as a biologist, "that a water may be as pure as can be as regards chemical analysis, and yet as regards the human body be as deadly as prussic acid, and, on the other hand, may be chemically gross and yet do no harm to anyone." "I am aware, " continued he, "that chemists may consider this as a terrible conclusion, but it is true, and if the public are guided by percentages alone they may often be led astray. The real value of a determination of the quantity of organic impurity in a water is, that by it a very shrewd notion can be obtained as to what has had access to that water."
