POPULAR SCIENCE MONTHLY 



" muzzled " for expressing his thoughts ? In 

 almost all cases it is the story of Galileo 

 over again. In art, science, and social re- 

 form he sees far beyond his fellows. Society 

 can not accept him because it has not the 

 vision of a genius. He contradicts its judg- 

 ment 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 Peri- 

 odicals* was issued in 1885, and was in- 

 tended to embrace the principal independent 

 periodicals of every branch of pure and ap- 

 plied 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 char- 

 acter of the journal or its right to be classed 

 as a periodical was doubtful, and in other 

 debatable cases, the compiler followed Zuch- 

 old'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 neces- 

 sary 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, to- 

 gether with about 3,600 new titles, bringing 

 the whole number of titles up to 8,4*77, to- 

 gether 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 peri- 

 odicals 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 li- 

 braries 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 volun- 

 tary 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 physio- 

 logical 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 phi- 

 losophy from Kant to Lotze. The author 

 has tried to avoid obtruding his own opin- 

 ions, expressing an individual judgment only 

 on matters of doubtful interpretation ; and 

 he recognizes that speculation and the intro- 

 spective method of studying the will appear 

 to have almost reached their limits. 



Dr. Frank Overton's textbook of Ap- 

 plied 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 funda- 

 mental nature and importance is emphasized
