an intermediate. Objectionable also is the fact that the outdated Crum-Brown and Gibson rule is the only help given the student on the matter of orientation. Molecular rearrangements are treated much too casually. The reader is introduced to this subject in a footnote (page 107) during the discussion of pinacol and pinacolone. There is no comment other than to call it "a remarkable intramolecular interchange." The next rearrangement is the Kolbe synthesis of salicylic acid. No longer is this considered to be remarkable, but it is spoken of merely as "an intramolecular change." I t would seem that the author should give the student more enlightenment on the processes involved. One final criticism is that the book reflects an unfortunate nationalistic bias. Of approximately seventy references which are made to the work of chemists who are now living, about sixty of these are references to the work of British investigators. This book is attractively hound and well printed. It should be helpful to students in their supplementary reading. As a textbook of elementary organic chemistry, however, it impresses the reviewer as being definitely inferior to many which are now available. CHARLESD. HUED NOBTBWB~TBRN UNIVBPSLTY EVANITON.

This is the third edition of a well-known book which should be available to every student who writes articles or reports an scientific or technical subjects. It is primarily a reference book on matters relating to style and form and the mechanical construction of a scientific or technical report. Some of the topics covered are: suggested outlines, suggestions on subject matter and arrangement, use of tenses, capitals, abbreviations, construction of tables, literature citations, abbreviations for scientific publications, use of headings, proof reading, and illustrations. The purpose of the authors is well accomplished, and this little book answers almost any question pertaining to form which the prospective author of a technical report might put to it. The author states in the preface. "This handbook is not a manufactured product, not a collection of theories; it grew." To this reviewer it appears that some pruning of overgrown branches and some building up of undernourished ones would have added considerable value to this vegetative book. For example, seventeen pages are devoted to a description of four different methods of literature citations, and only five pages to general suggestions on subject matter and arrangement. A more symmetrical structure might have grown if the various branches and twigs described so well had been hound together in closer relation to the main stem. I n short, the reviewer believes that the book lacks an adequate treatment of subject matter and of the technic of developing the several sections of a report.
through three editions. I n 1901, Dr. Bailey was about fiftythree years old and Dr. Cady was a youth of twenty-five. Before going to Kansas Dr. Bailey had had teaching experience a t Yale and a t Lehigh. He died in 1933. The idea of having two men cooperate in preparing a textbook is usually a gwd one, particularly when one of the men is an experienced teacher and the other is a youth enthusiastic about new ideas. For that reason. the book by Bailey and Cady was one of the first to attempt to teach qualitative analysis on the basis of the Ionization Theory of Arrhenius and the Mass Law of Guldberg and Waage. By continuing this practice of having a young instructor active in revising the book, i t has been kept up to date during these forty years. Paul Y. Faragher prepared the eighth edition, and Arthur W. Davidson the ninth and tenth. A study of the curricula of about one hundred fifty colleges and technical schools of the United States shows that it is common practice to devote relatively little time to laboratory practice in qualitative analysis. I n many cases, the course is merely a part of the first year instruction. The h w k of Bailey and Cady, in its revised form, is more than adequate for all such courses. Most teachers will like the way in which the subject of the "oxonium" ion is discussed. The book states that "a hydrogen ion certainly combines with a t least one molecule of water to form the complex ion H(H*O)+ or HIO' which is called the oxonium ion" hut, since the exact extent of hydration of the ion is not very well known, the authors continue to write the chemical formulas of ions in solution as if they were anhydrous. The b w k makes note of the marked differencesbetween strong and weak electrolytes, and the limitations of the Mass Law are taken into consideration. The procedures have been modified somewhat, and some new tests described. About half the hook has printing on the left-hand pages only. and the right-hand pages are available for additional notes, or for writing balanced equations to illustrate the reactions studied. Teachers who have used the manual with their classes will undoubtedly welcome the new edition. It is well-written, and its doctrine is sound. WILLIAMT.

This book is one of The University Series the purpose of which "is to present. in an attractive form and in a concise, readable style, the truly amazing story of the life of mankindan authoritative survey of the physical and soeial sciences, history, philosophy, literature, and the arts. The books are not intended to be textbooks or to treat any subject in confusing detail." Professor French has done exceedingly well by chemistry in his contribution t o this series. "The Drama of Chemistry" is developed h i s t o r i d y with particular einphasis on theory in ten concise chapters; vie., Early History. The Awakening of Chemistry. The Chemical Revolution, The Era of Empiricism, The Theory of Ions. Structure of Atoms and Molecules, Organic and Biological Chemistry, Chemistry and Civilization, The Chemist and His Work, and The Future of Chemistry. Appended are suggestions for future reading, a glossary, and an index. gum^ TO THE STUDYOF QUALITATIVE ANALYSIS. LABORATORY Thoroughly modem in outlook. such topics as the modern E . H. S. Bailey.
