University. v+123 Taylor & Company, may be able to secure technical knowledge of physics without becoming an expert engineer. Some of the cuts might have been improved upon, but this fact does not in any way injure the nature of the text. The book consists of seven chapters, the major paragraphs of which begin with bold faced type. At the close of each chapter there are many experiments given which are discussed in the body of the chapter. There are several tables of physical constants appended. There is a splendid index of seven double column pages. The volume is worthy to be in the library of every physicist and technical man. C. H. S. Airplane Characteristics, by Frederick Bell, Cornell pages. 16x23 cm. Cloth. 1918. $1.60 net. Ithaca, New York. Whenever anything new appears in science, or whenever a change in the world's history is brought about, books are bound to appear discussing this phase of progress. This is one of the first books that have b en produced on aeronautic which it is possible for the ordinary layman to read and understand, for an extended knowledge of mathematics is not necessary to the reader. The volume is written by a past master in the theo y of airplane characteristics. The author has produced a book from his fund of knowledge which is second to none in excellence. The cuts and diagrams are selected to show just what the author discusses. It is a text that ought to be familiar to every person in this country who is in any way connected with the aviation corps of the United States Government. There are four appendices, the first being a complete glossary of terms used in aviation. The others are of a more technical nature. Physics teachers in schools and colleges should send for a copy of the book. C. H. S. The Vo ational Education of Girls and Women, by Albert H. Leake, Inspector of Manual Training and Household Arts, Ontario, Canada. Pages xix +430. 13x19.5 cm. Cloth. 1918. $1.60. The Macmillan Company, New York City. This book has been prepared in a great measure for the large number of instructors who are engaged in the teaching of our pupils in the lower schools. It is intended likewise to appeal to students in normal schools and colleges who are preparing themselves to become teachers of vocational instruction of girls and women. The author does not attempt to discuss any detail of industrial occupation which is not open to women, but he bears down heavily on the way in which girls and women should be instructed in order to be able to earn a livelihood in any vocations which they may feel themselves competent to follow. The book is the result of many years' experience in practical manual training, household science, and industrial education in general. There are fourteen chapters, each of which is divided into many important topics. The major paragraphs have the subject of the discussion printed in bold faced type. The volume is interesting to read, not only for he teacher but for the ordinary lay-woman. It is printed in 10 point type, on uncalendered paper, thus reducing the glare o reflection to a minimum. The half tone illu trations have been selected with care. There is a bibliography appended, and there is also a complete double column index of ten, pages. The book deserves a wide circulation. C. H. S. Mammalian Anatomy, with special reference to the Cat, by Alvin Davison. Ph. D., third edition, revised by Frank A. Stromsten, D. Sc. illustrations. 243 pages. 14 X20 cm. P. Blakiston's Son & Co. $2.00 net. 115 As indicated above, this is a revised edition of a standard work. The authors say with truth that "the great value of this manual has been its usable size and its concise elementary nature." They might have added that it is well and clearly written and planned and copiously illustrated. The title gives a correct idea of its scope. A good book. W. W. Principles of Economic Zoology, by L. S. and M. C. Daugherty. Second edition revised. 301 illustrations. 428 pages. 14x20 cm. W. B. Saunders Company. $2.00 net. The first edition was reviewed in the columns of this magazine on its first appearance. As this edition has made few changes, it will not be necessary to go into details. The writer of this review could never understand why the title "Economic Zoology" was given to the book, for there is certainly no great amount of economic matter in the book. It seems to us that the natural history of animals, however, is an especially strong feature of the book. For schools which need this side of the work, as, perhaps, state normal schools, this book should present a strong appeal. It is a good book of its type and useful as a reference book in the high school classroom as well as a text for certain types of schools. W. W. Agricultural Bacteriology, by H. W. Conn, Ph. D., third edition revised by Harold Joel Conn. 63 illustrations. 357 pages. 14 X20 cm. $2.00 net. P. Blakiston's Son & Co. Owing to the author's death the revision of this book has been undertaken by another to bring the work up to date with more recent discoveries, especially in the lines of soil bacteriology, control of milk supplies and plant diseases. Professor Conn's books are always well written and especially notable for their clearness of diction. These good qualities have been retained in the revision. The book is divided into five parts and after two chapters of a general and introductory nature there follow chapters on "Bacteria in Soil and Water"; "Bacteria in Dairy Products"; "Relation of Microorganisms to Farm Products"; "Parasitic Bacteria" and an appendix of laboratory directions. The treatment is non-technical and the style so clear that these important topics may be read and assimilated by the practical worker as well as by college students for whom the book is written. It is impossible in a brief review to give an adequate idea of the many good features, but a few may be mentioned. Throughout the work, but more especially following the more scientific exposition of a topic, the practical farm aspects of the topic are brought out. Some of the more important topics treated are those of organisms of the soil and of milk and their various applications. Knowledge of soil life is of vast importance to agriculture, and its importance can hardly be overestimated. Books which put this knowledge in form for wider circulation are especially valuable. W. W. Exercise and Review Book in Biology--New World Science Series, by J. G. Blaisdell, Yonkers High School. 152 pages. 20×26 cm. 21 illustrations. 80c. World Book Company. This book is planned by the author to be a "laboratory guide, a notebook and a review book" for student use in the high school. The guide consists of directions for performing the experiment or other work of the lesson, followed by questions for observations and conclusions. All questions are followed by blank lines for an answer. Occasionally there are blanks for drawings, while at other times the drawings are already made for the pupil with letters for labelling the parts. The teacher supplies the material, the pupils answer the questions, doing whatever obser vation or thought work the questions require. The course included is fairly comprehensive, covering plants, animals and human physiology. The book is written especially for New York schools. Such a scheme may be the best that can be done for schools with poorly trained teachers and large classes, or where the teacher is burdened with too many subjects. However, it should be the last resort, for it is bound to kill initiative in both teacher and pupil. Any course in biology, while including the great fundamentals of the subject, should be made to fit the local environment of the school as well as adapted to the pupils, the equipment and the teacher himself. Stereotyped sets of questions must inevitably lead to formality and stiffness in the course unless the teacher is unusually resourceful. W. W. The Teaching of Agriculture, by Aretas W. Nolan, University of Illinois. 277 pages. 12 x 19 cm. $1.30. Houghton Mifflin Company. Agriculture, as a part of the curriculum of high schools, is a very new subject. Like all new subjects, its teaching methods are somewhat unorganized. It takes many years to standardize the methods of teaching a subject so that the best results may be obtained. However, agriculture is making rapid progress toward better and more systematic methods. This progress is helped along in this case by the very many excellent texts that have come off the press in the last year or two. But textbooks are not all that is needed, for each book covers only a portion of the field. We needed something that would give a broader outlook and the proper proportions and setting of each branch of the subject. This organization of the field Professor Nolan has attempted in his "Teaching of Agriculture." It will not only be a source book of suggestions for the courses in agriculture but it is to be hoped it may aid in a better organization of the courses of study offered. There has been much perfunctory and consequently poor work in the teaching of agriculture, due to lack of standardization. There being no standard of attainment teachers, often overloaded with several subjects, have been tempted to be content with a very inadequate output. Of course, no sensible teacher will think of attempting to use the outlines the book offers bodily without change. Courses of study and the curriculum itself should be adapted to and built to suit the needs of that particular school and neighborhood. The book contains a great abundance of outlines of courses, suggestions, data and various other helps for the teacher. The advice for the teacher appears always sound and well taken. We trust that every teacher of agriculture may have opportunity to read and use the book. W. W. DIRECTORY OF SCIENCE AND MATHEMATICS SOCIETIES.
