Decennial Publications of the University of Chicago. Studies in General Physiology. By Jacques Loeb. 2 Vols. Chicago: The University of Chicago Press, 1905. Octavo, pp. 782. In these two splendidly printed volumes, Prof. Loeb has collected his numerous papers on General Physiology--a subject with which his name has been intimately associated for many years. Particularly noteworthy in this collection is the proof of Prof. Loeb's theory that the heliotropism of animals is identical with that of plants, that, in other words, a moth flies to a flame for the same reason that a plant turns its leaves to the rays of the , sun. Other subjects that find a place in the volumes are Instinct and Will in Animals, Physiological Effects of Lack of Oxygen, Experiments on Cleavage, The Development of F'ish Embryos with Suppressed Circulation, The Influence of Light on the Development of Organs in Animals, Experiments on Artificial Parthenogenesis. Modern Electricity. A Practical Working Encyclopedia. A Manual of Theories, Principles, and Applications. By James Henry, M.E., and Karel J. Hora, M.Sc. Chicago: Laird & Lee, 1904. 16mo.; pp. 355; 150 illustrations. Price, cloth, 1; leather, 1.50. There is always room for a practical, simple, and comprehensive treatise upon the applications of electricity to its manifold forms of modern usage. One of the essentials of such a book should be clarity of statement and practicality of text and illustrations. The book before us combines these essentials in marked degree. The student is taken by easy progressive steps through the various chapters, from the standpoint of the beginner to that of the accomplished and advanced electrician. The entire field of electrical engineering is covered, and the whole has been most carefully edited and arranged, with a view to furnishing electricians and mechanics with a thoroughly reliable book of convenient size at a moderate price. Elements of Plane Surveying. (Including Leveling.) By Samuel Marx Barton, Ph.D. Boston: D. C. Heath & Co., 1904. 8vo.; pp. 255. Price, 1.50. This work is so arranged that it will be useful as well to a teacher of but little practical experience and to a student who is studying the subject of surveying privately. Many questions that are apt to confuse a student are carefully dealt with, and clearly explained. The author has had experience both in the classroom and in the field, and is, therefore, able to recognize and explain those parts which are troublesome to beginners. The following points are especially dealt with : Careful description of the instruments ; explicit directions for making a resurvey in accordance with different data to be had ; discussion on the declination of the needle ; simple methods of obtaining a true meridian line ; suggestive forms for field notes ; and many illustrative examples, together with a clear and complete set of tables. Electricity in Everyday Life. By Edwin J. Houston, Ph.D. New YorX: P. F. Collier & Son, 1905. Three volumes; 12mo.; pp. 1,750. The title is well chosen. Electricity has come to be such a common part of everyday life that no one can afford to be without some knowledge of the subject. Electro-technical phraseology is used in the daily newspapers. We come across electricity in a hundred-and-one different ways. Newspapers are printed by electricity ; telephone, telegraph, automobiles, cars, lights, etc., are electrically operated ; in fact, wherever we turn, we find electricity largely used. It is to supply the nontechnical man with information upon electricity that this work is written. Very practical explanations are given of all electrical apparatus in daily use, and no man can consider himself well informed without such a knowledge of electricity in this the electrical age. The Organization of Corporations. By Thomas Conyngton, of the New York Bar. New York: The Ronald Press Company, 1904. 8vo.; pp. 352. Buckram binding, net, 2.50; prepaid, 2.70; sheep binding, net, 3; prepaid, 3.20. This book, which discusses some of the many questions which are considered at the time of the organization and incorporation of every company, is by the author of Corporation Management, and it is published as a companion volume. The author states that in writing the book it was his intention to place in convenient form before the reader a manual of reference, which would assist him in refreshing his memory or be of service in obtaining an elementary knowledge of the law and of the practice usually followed in incorporating companies. The book is by no means a comprehensive work on the subject of corporation organization, but it does contain chapters on the principal subjects which are of interest to the incorporators of companies, and as the chapters are concise and logical, the book, as a manual, should, In its own field of usefulness, although perhaps a limited one, be of service to the busy lawyer. The author has in many places made suggestions for the protection of different interests ; a chapter being devoted to the protection of minority interests, and another to the protection of inventors at the time of the assignment of their patents to the corporation.
