Abstract

(1) THIS is the first of a new series of monographs on colloid chemistry, and the preface, signed by Prof. Zsigmondy alone, serves as a general introduction of the enterprise. The distinguished author deals somewhat severely with certain tendencies which he discerns in the rapid development of the discipline during the last twenty years; the failure of authors to maintain the standard expected from workers in the field of exact science; a preference for philosophical treatment and undue generalisation; neglect of the chemical nature of the systems investigated, and other shortcomings. Against these has to be set much exact work carried out by isolated investigators, and the object of the series is to collect and co-ordinate such work and to make it generally accessible.
