THE POPULAR SCIENCE MONTHLY. 



cover the laws enacted in 1893 by thirty- 

 nine States and one Territory. In most 

 cases the laws arc briefly summarized as 

 well as cited, in order to present clearly and 

 concisely material for comparative study of 

 the most recent phases of State legislation 

 on all subjects of general interest. (Pub- 

 lished by the University of the State of New 

 York, Albany. Price, 20 cents.) 



In a paper on the Prevention of Tuber- 

 culosis in Ontario, read before the Ontario 

 Medical Association, Dr. E. Herbert Adams 

 advocates such measures of administration 

 and education as will make sure the total 

 destruction of the products of expectoration, 

 and of the germs of the disease in every 

 other form. 



The Journal of Social Science, No. XXXI, 

 January, 1894, includes more than half of 

 the Saratoga papers of 1893. The one oc- 

 cupying the first place, and probably of 

 widest general interest, is the tribute of Mr. 

 Edward B. Merrill to the life and public 

 service of George William Curtis. Other 

 papers are the report of F. B. Sanborn on 

 Socialism and Social Science ; a review of 

 recent progress in Medicine and Surgery, by 

 Dr. Frederick Peterson ; Compulsory Arbi- 

 tration, by H. L. Way land, D. D. ; three pa- 

 pers in the Finance Department, relating to 

 the silver question, bimetaUism, and The 

 Three Factors of Wealth; three papers in 

 the Social Economy Department two of 

 them relating to Mutual Benefit Societies 

 and the Sweating System ; three papers in 

 the Jurisprudence Department; and The 

 Education of Epileptics, by Dr. L. F. Bry- 

 son. (Pubhshed by G. P. Putnam's Sons, 

 New York, and Damrell & Upham, Boston.) 



In planning his First Course in Science, 

 the author, John F. Woodhull, believing that 

 the study of text-books alone can not be 

 classed as work in science, and that illustra- 

 tive or object teaching can be so classed 

 only in part, has attempted to devise means 

 by which apparatus could be put into the 

 hands of each pupil as early as possible. A 

 text-book, however, is essential, and it is 

 given here in two separate but mutually de- 

 pendent volumes. One volume contains 

 directions to pupils for performing their ex- 

 periments, sufficient to prevent aimless work, 

 and yet not so full as to interfere with the 

 inductive method. The other volume, the 



Text-book, is similar to the ordinary text- 

 book, telling how the experiments should 

 result, giving the pupil a correct form of 

 statement for the conclusions and laws 

 which he has learned in a practical way, and 

 furnishing other information. The experi- 

 ments are on light. On every right hand page 

 in the Book of Experiments is left a space 

 for the insertion of the pupil's own notes.

Prof. Max MiiUer, replying to an accusa- 

 tion that his book on the Srience of Thought 

 was thoroughly revolutionary and opposed to 

 all recognized authorities in philosophy, de- 

 scribes it as rather evolutionary, the out- 

 come of that philosophical and historical 

 study of language which began with Leib- 

 nitz and has now spread and ramified so as 

 to overshadow nearly all sciences. The 

 fundamental principle of the book is that 

 language and thought are identical, and one 

 can not be without the other. The three 

 lectures on the subject published by the 

 Open Court Publishing Company, Chicago, 

 are regarded by the author as a kind of 

 preface or introduction to the larger work. 

 To these lectures are added in an appendix 

 the correspondence between Prof. Miiller and 

 Francis Galton, the Duke of Argyll, George 

 J. Romanes, and others, on Thought without 

 Words. The lectures are sold, bound in 

 paper, for 25 cents. 



The papers in the fourth number of 

 Yolume II of the Bidlctiyi from the Labora- 

 tories of Naturcd His'ory of the State Uni- 

 versity of Iowa are technical. Mr. B. Shi- 

 mek's account of A Botanical Expedition to 

 Nicaragua has- a few features of general in- 

 terest, but the author's mind was too singly 

 fixed upon his collections to permit him to 

 enlarge upon them. Of the other papers, 

 four are upon the slime-molds and other 

 fungi of Nicaragua, Central America, east- 

 ern Iowa, and Colorado ; two relate to the 

 physiology of the Coleoptera ; two, by F. S. 

 Aby, relate to the physiology of the Domes- 

 tic Cat, and to observations on a case of 

 Leucaomia ; and A New Cycad is described 

 by Thomas H. McBride. (Iowa City, Iowa. 

 Price, 50 cents.)
