Abstract

(1) GRAHAM'S pioneer work on colloids is bearing rich fruit to-day, and colloid chemistry is becoming more and more important in theory and in practice. There are, of course, several text-books dealing with the subject generally, and giving descriptions of methods used in preparing colloidal substances. Mr. Hatschek himself is known as the author of one of these, and as the annotator of another, besides being the writer of a notable series of articles on colloids. There is, however, no laboratory manual similar to the present work. To expound the theory of the matter, lectures are good things, and books necessary; but the laboratory remains always the “forecourt of the temple” of colloid philosophy; it is only there that the student gains real familiarity with the characteristic properties of colloidal substances. And in the laboratory a well-devised series of practical exercises is invaluable for economising the worker's time, sparing his temper, and leading him to good results. The author's aim has therefore been to give “accurate and very detailed” directions for carrying out the fundamental operations. He is qualified to write a manual based upon personal experience of the special difficulties met with in the practice of this branch of chemistry, and he has done it very well. Both students and teachers have reason to be grateful to him.
