This is the last of a six volume series published over a period covering the past two decades (volume I, 1926) that deal with various phases of colloid chemistry. The series covers a diversity of scientific interests represented by the contributions of numerous authorities in the field that have been collected and edited by the author. Volume V: Theory and Methods, Biology and Medicine, reviewed in The Journal, June 23, 1945, illustrates the wide range of application that colloid chemistry has engendered.
The present volume, as suggested by the title, is divided into two sections: part I, dealing with general principles and specific industries, and part II, dealing with synthetic polymers and plastics.
