566 "muzzled" for expressing his thoughts? In almost all cases it is the story of Galileo over again. In art, science, and social reform he sees far beyond his fellows. Society can not accept him because it has not the vision of a genius. He contradicts its judgment and is fortunate when he escapes with the name of "crank." The military hero does not enter into this category: he glorifies the past rather than the future; he justifies the multitude in a good opinion of itself and, is therefore always received.

The first edition of Professor Bolton's Catalogue of Scientific and Technical Periodicals was issued in 1885, and was intended to embrace the principal independent periodicals of every branch of pure and applied science, published in all countries from the rise of this literature to the present time, with full titles, names of editors, sequence of series, and other bibliographical details, arranged on a simple plan convenient for reference; omitting, with a few exceptions, serials constituting transactions of learned societies. In cases where the scientific character of the journal or its right to be classed as a periodical was doubtful, and in other debatable cases, the compiler followed Zuchold's maxim, that "in a bibliography it is much better that a book should be found which is not sought, than that one should be sought for and not found." The new edition contains as Part I a reprint from the plates of the first edition, with such changes necessary to bring the titles down to date as could be made without overrunning the plates; and in Part II additions to the titles of Part I that could not be inserted in the plates, together with about 3,600 new titles, bringing the whole number of titles up to 8,4*77, together with addenda, raising this number to 8,603, minus the numbers 4,955 to 5,000, which are skipped between the first and second parts. Chronological tables give the dates of the publication of each volume of the periodicals entered. A library check list shows in what American libraries the periodicals may be found. Cross-references are freely introduced. The material for the work has been gathered from all available bibliographies, and by personal examination of the shelves and catalogues of many libraries in the United States and Europe, and from responses to circulars sent out by the Smithsonian Institution. The whole work is a monument of prodigious labor industriously and faithfully performed.

In Theories of the Will in the History of Philosophy a concise account is given by Archibald Alexander of the development of the theory of the will from the early days of Greek thought down to about the middle of the present century; including, however, only the theories of the more important philosophers. In addition to contributing something to the history of philosophy, it has been the author's purpose to introduce in this way a constructive explanation of voluntary action. The account closes with the theory of Lotze; since the publication of which the methods of psychology have been greatly modified, if not revolutionized, by the development of the evolutional and physiological systems of study. The particular subjects considered are the theories of the will in the Socratic period, the Stoic and Epicurean theories; the theories in Christian theology, in British philosophy from Bacon to Reid, Continental theories from Descartes to Leibnitz, and theories in German philosophy from Kant to Lotze. The author has tried to avoid obtruding his own opinions, expressing an individual judgment only on matters of doubtful interpretation; and he recognizes that speculation and the introspective method of studying the will appear to have almost reached their limits.

Dr. Frank Overton's textbook of Applied Physiology makes a new departure from the old methods of teaching physiology, in that it begins with the cells as the units of life and shows their relations to all the elements of the body and all the processes of human action. The fact of their fundamental nature and importance is emphasized
