Edition I have adopted the International Atomic Weights for 1912, and have accordingly entirely re-calculated the gravimetric and volumetric factors, percentage compositions of commonly occurring compounds, etc. In all cases the full molecular weights, without any reduction, and seven-figure logarithms were used, the logarithms being finally reduced to five figures, which are sufficient for all practical purposes. The above-mentioned tables have been considerably amplified; and the gravimetric and volumetric factors have been printed in larger type than heretofore, so as to secure greater ease and certainty in reference. The section devoted to Weights and Measures has been entirely re-written in accordance with the most recent legislation on the subject. It should be noted that the legal Imperial Weights and Measures and the Imperial equivalents of Metric Weights and Measures are authorized, from time to time, by various Orders in Council. Several useful approximations have been added. I have pleasure in recording my thanks to Major P. A. Mac Mahon, F.K.S., the Deputy Warden of the Standards, for assistance kindly rendered in this section. In the Water and Sewage section 1have given a much fuller account of the determination of nitrates by the phenoldisulphonic acid method, which I have had in use for the past twenty-eight years; also an epitome of Chamot, Pratt, and Redfield smethod of procedure. I made some comments on the latter in The Chemical News, 1911, 104, 235. The section dealing with specific rotatory power and cupric reducing power of the carbohydrates has again been thoroughly revised, and, I believe, brought up to date. I am indebted to Dr. E. Frankland Armstrong for kindly examining my revise of this portion of the book. The Kjeldahl table has been re-calculated and extended.(Typographical errors above are due to OCR software and don't occur in the book.)About the Publisher Forgotten
