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, EtcThe arguments in favour of this or that view have hitherto been conducted too much on a priori lines and an attack on the position from the other side, - eu appeal to experience as opposed to mere anticipation, - will show us that pet theories are not only not always supported by facts, but must some times be very much modified by them.It is not proposed to enter into the consideration of any technical details relating to water analysis and happily it is unnecessary. The processes by which 'chemists arrive at their results, and which during the last few years have been much improved in the direction of extreme accuracy, are not the subject of variance, with one notable exception however, viz - that of the estimation of organic matter. Of the several methods in use for the estimation of organic matter, each is vaunted by its originator, as being the best and only reliable one, and the only agreement that seems so far possible amongst analysts (though here it must be admitted the unanimity is complete), is in decrying every other person's process.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
