NEW BOOKS. 545 psychology. As educators, the authors have something to say ; as psychologists, they have simply furnished a compilation of the opinions of Bain, Spencer, Sully, etc., without regard to system or even to uni- formity of terminology. One must not demand everything of a text-book ; but one may demand knowledge of the great current issues, and Messrs. Dexter and Garlick appear to be wholly unfamiliar with the work of James, Stumpf and Wundt. The chapters are entitled : Physiology and Psychology ; the Three Phases of Mind ; Attention ; Sensation (organic senses, taste, smell) ; Perception (senses of sight, touch, hearing) ; Observation ; Development and Training of the Senses ; Memory ; Imagination ; Conception ; Judgment ; Reasoning ; Apperception ; Psychological Basis of the Kindergarten System ; Feelings (egoistic, social) and Sentiments (in- tellectual, aesthetic, moral) ; Will ; Habit ; Character ; Discipline. There are sixty-four figures in the text, most of them well-selected and useful. Every chapter ends with a summary and a list of questions, and an appendix contains specimen examination papers. Indeed, what one may call the mechanical side of the making of the book is excellent. But neither will it help the reader to become a psychologist nor does it furnish the outline of a modern system of psychology. General Physiology : an Outline, of the Science of Life. By MAX VER- WORN, a. o. Professor of Physiology in the University of Jena. Trans- lated by F. S. LEE, Adjunct Professor of Physiology in Columbia University. With 285 illustrations. London and New York : Mac- millan & Co., 1899. Pp. xvi., 615. Price 16s. ; $4. Prof. Verworn's Allgemeine Physiologic (1894, second edition, 1897) is an excellent book in the German, and no less excellent is Prof. Lee's trans- lation. We are glad to call the attention of psychologists to it, and heartily subscribe to the words of the translator's preface : " The work has been welcomed by European and American biologists, who have felt the need of a review and summary of the rapidly accumulating details of cell-physiology, and its ability and suggestiveness have been widely recognised. Many of the special views of the author have encountered opposition a fact that, perhaps, is indicative of their value yet, how- ever much we may agree or disagree with him upon special points, we must all acknowledge his breadth, and be grateful to him for present- ing such a wealth of facts, and for pointing out so clearly the possibilities of research." Prof. Verworn's well-known Psychophysiologische Protis- tenstudien (1889) is a guarantee of his interest in, and familiarity with, fundamental psychophysical problems. The present volume contains a bibliography and a good index. The Principles of Biology. By HERBERT SPENCER. Vol. i., revised and enlarged. London: Williams & Norgate; New York: D. Appleton & Co., 1898. Pp. xii., 706. Price 18s. We are glad to add our voice to the general chorus of congratulation which has greeted the veteran author of the Synthetic Philosophy on the appearance of this second edition of vol. i. of his Principles of fiiology. Additions of prime importance have been made to the text of 1864. We find new chapters on Metabolism, on Structure, on the Dynamic Element in Life, on Cell-life and Cell-multiplication, on Genesis, Heredity and Variation, and on Recent Criticisms and Hypotheses. The chapter on the Arguments from Embryology has been for the most part rewritten. 35
