THE POPULAR SCIENCE MONTHLY 



Practical Botany, Structural and Sys- 

 tematic, etc. By August Koehler, 

 M. D., Professor of Botany in the College 

 of Pharmacy of the City of New York. 

 Copiously illustrated. New York: Hen- 

 ry Holt & Co. 12mo, pp. 400. Price, 

 $3.00. 



The author, believing that "the study 

 of botany cannot become truly profitable 

 until a number of plants have been identi- 

 fied by the student, and their images re- 

 ceived into his memory," has constructed 

 a book which is an artificial key to "stimu- 

 late the unlearned," and act as a labor-saver 

 to those already somewhat acquainted with 

 the science. It departs from the ordinary 

 system of classification, in being arranged 

 according to the old dichotomal method. 

 The natural tendency of this might, perhaps, 

 be to suggest names rather than the asso- 

 ciation of principles. Those, however, who 

 are desirous of rapid action, and speedy re- 

 sults, will find here a book for their pur- 

 pose in a neat and convenient form. 



Theory op Medical Science : The Doctrine 

 of an Inherent Power in Medicine a 

 Fallacy. The Ultimate Special Proper- 

 ties of Vitality and the Laws of Vital 

 Force constitute the Fundamental Basis 

 of Medical Philosophy and Science. By 

 William R. Dunham, M. D. Boston : 

 James Campbell. Pp.150. Price, $1.25. 



The title-page speaks for itself, and in- 

 dicates the theory on which this book was 

 written. The work was published with the 

 hope that it might recover the " funda- 

 mental principles involved in a correct the- 

 ory of medical science," assist the profes- 

 sion in the details of practice, and enable 

 the non-professional to distinguish between 

 quackery and rational practice. The au- 

 thor finds fault with the medical profession 

 because it continues to follow the ancient 

 interpretations of the science, but seems 

 unwilling himself to adopt the results of 

 those who are doing most for the further- 

 ance of correct principles in regard to 

 mind and body. 



California Notes. By Charles B. Tur- 

 kill. San Francisco : Bosqui & Co. 

 Price, $1.50. 



The " Notes " is a description or guide 

 through different sections of California, in 

 which the author conducts his readers to 

 the places visited by him. Among the 



subjects represented in the book are, " San 

 Francisco," " Into the Heart of the Foot- 

 Hills," " Calaveras County," " Gold-Mines," 

 " The Yosemite Valley," etc. This volume 

 is the initial number of a series. 



Elements of Physical Manipulation. By 

 Edward C. Pickering, Thayer Profess- 

 or of Physics in the Massachusetts 

 Institute of Technology. Part II., 

 pp. 316. Price, both parts, $4.00. 



This second volume, like the first, is 

 designed as a special text-book for the lab- 

 oratory. The text is made up principally 

 of experiments, giving a description of the 

 instruments to be used, and a plan of what 

 is to be done. Among the subjects dis- 

 cussed are " Electricity," " Meteorology," 

 and " Astronomy." The latter is a new 

 feature in laboratory practice, but there is 

 no reason why it should not be taught 

 practically, as well as chemistry or physics.
