The remaining chapters deal with Reasoning, Movement, Instinct, Emotions, Will, Hypnotism, Necessary Truths; in addition to the characteristics already indicated, we find here a wise use of the facts of Morbid Psychology, of the inferences from the abnormal to the normal. This naturally stands out prominently in the discussion of Hypnotism—so recent and yet so essential a department of mental science. When we close the cover of the second volume we do so with the feeling that our mental horizon has been enlarged, our interests have been quickened, our attention has been held, our time agreeably spent,—and yet the result of all this reading seems intangible, diffuse, scattered, unsatisfactory. The scholar and the professor always retain the student feeling and the student habit of thought; and what is unpedagogic for the one is uneconomical for the other. A logical order of exposition, a unifying grouping of topics, a just perspective of details, a painstaking selection of facts, constitute much to convert useless knowledge into useful science; such works contain a large element of drudgery, must be impersonal in one sense of the term, and yet are not inconsistent with a high degree of originality, but it is such works that are enormously helpful, that form landmarks by which progress is measured and retained. These useful qualities we miss in Professor James's work. True, it does not pretend to possess them, but psychological text-books are not written every day, and when so influential a one appears, the wish that its utility shall reach a maximum demands expression. Finally, it is a work destined to be much quoted, to arouse considerable discussion, to excite quite different opinions from different critics, and so, every one interested in modern Psychology will find it necessary and profitable to learn at first hand this important American contribution to the science of Psychology. J. J. THE SCIENCE OF THOUGHT. By _Charles Carroll Everett, D. D._ Boston: De Wolfe Fiske & Co. Revised edition. An excellent manual of that which is accepted as logic. The author is a disciple of Hegel, and throughout conforms his treatment of the topic to the lines laid down by his master, although in various connections where these lines permit, the author contributes from his own resources, and from other masters, much needed supplementary matter.
