    There has not hitherto been any English work dealing exclusively with the chemical analysis of Oils, Fats, and Waxes. I was on the point of writing one, in compliance with a wish expressed to me by several friends, when I was asked by Professor Benedikt to render his German work, Die Analyse der Fette unci JVachsarten, into English, with such alterations as I thought necessary. As his book is undoubtedly the best on that subject, I thought, instead of adding to the number of text-books, it would be more useful to found on it an English edition, and to increase its usefulness as far as I was able. My task has therefore been a threefold one, to wit—to translate, revise, and enlarge the German work. Little can be said under the first head. A literal translation of the text, as far as it was retained, was, of course, out of the ques- tion. Especially when describing analytical processes the almost epic breadth in which our Continental brethren indulge made it necessary to leave out many details which would be found wearisome by English chemists. The revising of the work was the most important part of my task. I have often asked myself the question whether the writer of a book of this kind should not have himself tested all the methods he puts before his readers. But, on the one hand, it is impossible to personally examine every little modification or process, the description of which helps to swell the literature of our subject, whilst on the other hand to neglect this lays one open to the charge of hasty and presumptuous criticism. In revising I had to be guided by such experience as I have gained during many years devoted to the chemistry of Fats and Oils
