DR. MARTIN'S book is best considered as an extremely practical guide to laboratory experiments for the student of synthetic resin chemistry, interspersed with an introductory survey of the theoretical side of this complicated field. The fifty-odd experiments are novel and well chosen ; and it is difficult to know where else one could find details of such an illuminating series. They are simple, they are specific, and they work. On this score the book is wholly admirable. Synthetic Resin Chemistry For Students. By Dr. S. R. W. Martin. Pp. vii + 160. (London : Chapman and Hall, Ltd., 1947.) 15s. net.
