Part 111 consists of thirty pages devoted to Health and Physical Education in Junior and Senior High Schools. The preface cautions the reader that will have t o he "material presented . interpreted in the light of different conditions found in communities of varying size." Throughout the volume the reader should bear in mind the committee's definite policy that "none of the conclusions are presented with finality."

Course of Studv in Chemistw for the ~uhlishedby the Senior High &ool. State Department of Public Instruction of New jersey, 1928. 67 pp. 23 X 15.5 cm. This report includes the following topics: Outline of Subject Matter, Terms, Chemical Equations, Experiments, A Few Suggested Demonstrations, Reference Materials, The Place of the History of Chemistry in a HighSchool Chemistry Course, A Brief Statement of the Main Theories Included in the Suhject-Matter Outline. The State Department of Public Instruction of New Jersey had two purposes far issuing this publication: (1) to set stand-
ards of work of secondary grade in this science, and (2) t o outline a field of chemical science that will serve to make the community more intelligent in and appreciative of the benefits of this branch of knowledge. The objectives which guided the committee in preparing this outline of the chemistry course are stated as follows: (1) T o provide an opportunity, as a basis of good citizenship, for pupils to become acquainted with some of the applications of chemistry t o home and community life, commerce, trades, and the professions. (2) To provide pupils with a broader appreciation and understanding of the world in which they live. (3) T o provide opportunity for gaining chemical knowledge which will contribute t o individual and community health. (4) To provide opportunity for training in the scientific method of thinking through the study of real chemical problems. (5) To provide pupils with a substantial foundation, so that the study of chemistry may be profitably continued if desired. (6) T o provide an opportunity for thinking and imagining in scientific terms, t o the end that the pupil may come t o a decision as t o whether chemistry offers for him a field for vocational activity. (7) T o provide interests which may function in a more worthy use of leisurr time. This publication contains many valuable suggestions and useful material for high-school chemistry teachers. M. W. G.
