Abstract

(1) DR. PRIDEAUX has compiled a book of problems to serve as exercises for students in physical chemistry. The students who have worked through these will not be able to complain that they have not been exercised suffici ently, as the examples selected are very numerous and by no means all easy. They are, however, selected directly from the original literature, and so require the student to give real solutions to real problems, instead of the sham answers to fictitious questions which so frequently disfigure books of chemical calculations. The form in which this excellent material has been published is much less satisfactory. The table of contents suggests that the volume is composed of eight chapters, but these do not appear in the text. The reader is informed on each of the 300 pages that the book he is studying is called “Problems in Physical Chemistry,” but no hint is given as to the topic that is dealt with on the pages at which the book is opened. The eight chapters run on continuously, and almost the only way to discover where one chapter ends and another begins is to turn back to the table of contents, for the chapters are not even allowed the luxury of begin ning at the head of a fresh page. As no index has been supplied, the contents of the book are far less accessible than they need be to a reader who does not wish to work right through the book from beginning to end.
