fact, general trends of data are used as a basis for conclusions. Except for this l i i tation the author mainly accomplishes his purpose. Where he fails, he so states. In this subject, which is of great interest to teachers of college chemistry, Dr. Noll has made definite progress. Although the problems outlined are not yet solved, they should encourage further work. It is unfortunate that the problem could not be considered also from the viewpoint of the chemist, as to actual professional accomplishments. This, of course, is the final test of the value of laboratory requirements in chemistry and a chemist wonders if even the most skilful of written examinations can replace it. The book might well have included a list of definitions for abbreviations. The frequent occurrence in the text of abbreviations which most teachen of chemistry will not understand limits considerably the value of the book. Although i t is a research in education, a style better adapted t o chemistry teachers would have resulted in the derivation of the maximum benefit for the teaching of chemistry. On line 11, page 87, there is apparently a misprint. The expression, "Group 111 a, which had only three hours of laboratory-" presumably should be "Group 111h, which had only three hours of laboratory-.'' W. E. BRADT

leave an imprint on the mind of the young experimenter as to the significance of formula and when he reaches the end of the book he most certainly will have retained some of them. The use of certain terminology is not to he ~ m m e n d e d ;thus "Old Man Chlorine," "Sweet Mamma Iodine," "Miss Bromine." and "Little Sister Fluorine" are endearing terms which the reviewer feels should not have heenincluded. The book is easy to read and should go far in helping to popularize chemistry. E. G. VANDEN BOSCHE UNIVBPSITY OIl M * . n * N D B*LT~MO.B. M*RYL*ND

Those familiar with the 1922 edition will find the general plan unchanged. Some of the discussion and questions have heen revised and nine new preparations are included which involve work with the less common elements such as cerium, titanium, selenium, molybdenum, and tungsten. The experiments are clearly written with detailed directions and the theoretical discussions are presented so simply and forcefully that a student should have no difficulty in understanding the work. Seventy-five preparations as well as many minor experiments are given, hence the individual teacher is permitted quite a wide choice of material. In addition to a table of solubilities the appendix indudes an excellent brief discussion on the structure of matter in connection with the periodic system. Aside from classroom work the dire=tions should prove valuable to many who desire explicit information on these special inorganic oreparations. . . . This book deserves the consideration of those teachers who have been seeking a different text for the more advanced freshman student. C H ~ ~ E. LW E ~m
