SCIENCE. 



[N. S. Vol. VII. No. 166. 



the diagram of chemical activities is largely 

 suppositious, and that substances may be located 

 here and there, with no indication decisive of 

 synthetic or analytic origin. 



The author includes many energy liberating 

 processes under respiration, whether attended 

 by excretion of CO2 or not, and emphasizes the 

 fact that it is only a link in the chain of meta- 

 bolic metamorphoses. It is, therefore, not al- 

 ways possible to determine the subjects or prod- 

 ucts of respiration. 



A comparison of the editions of 1881 and 1897 

 reveals the fact that Professor PfefFer no longer 

 deals with the organism as a purely chemical 

 and physical machine, but regards it from a 

 physiological point of view. Nowhere is this 

 more vividly apparent than in a paragraph 

 dealing with translocation, which is freely 

 translatable as follows: "In general, trans- 

 location is regulated by the vital activity. 

 By this the functioning apparatus is con- 

 trolled, and apparently the organism is capa- 

 ble of modifying the permeability of the proto- 

 plast temporarily in many ways. Indeed, 

 it is not improbable that the living protoplast, 

 by its own activitj'', not only conducts solid 

 particles and oil drops, but also under some 

 circumstances dissolved substances for which it 

 is not diosmotic. Furthermore, diosmose is not 

 dependent entirely upon the size of the dis- 

 solved molecules, since many colloids may be 

 easily taken up and given off." 



The terse, vigorous, concise style and gen- 

 erally high literary quality make this volume a 

 classic in botanical literature. The author has 

 rendered an inestimable service to biological 

 science by his masterly criticism and arrange- 

 ment of the accumulated results of research 

 upon the physiology of the vegetal organism, 

 and his vivid clear-cut delineation of the prob- 

 lems awaiting investigation will give a new 

 impetus to research in this and related lines. 



Arrangements have already been made for 

 the translation of the book into French and 

 English. The English edition will be prepared 

 under the direction of Dr. Ewart, whose inti- 

 mate acquaintance with the author and impor- 

 tant researches in the Leipsic Institute make 

 him especially well fitted for the task.

Beginning in 1893, the Boone and Crockett 

 Club has published on alternate years a volume 

 made up of articles on big game and big game 

 hunting, with tales of exploration in little known 

 lands. While written primarily for the sports- 

 man, these books contain much of interest to 

 the naturalist ; and to the student of the larger 

 mammals they are indispensable. The new 

 volume, 'Trail and Camp Fire,' contains the 

 following: 'The Labrador Peninsula,' A. P. 

 Low ; ' Cherry,' Lewis S. Thompson ; ' An Afri- 

 can Shooting Trip,' Wm. Lord Smith ; ' Sinta- 

 maskin,' C. Grant LaFarge ; ' Wolves and Wolf 

 Nature,' George Bird Grinnell ; 'On the Little 

 Missouri,' Theodore Roosevelt; 'Bear Traits,' 

 George Bird Grinnell, J. C. Merrill, Theodore 

 Roosevelt and Henry L. Stimson ; ' The Adiron- 

 dack Deer Law,' Wm. Cary Sanger ; 'A New- 

 foundland Caribou Hunt,' Clay Arthur Pierce ; 

 'Origin of the New York Zoological Society,' 

 Madison Grant. To these is added a chapter 

 on ' Books on Big Game ' — one of the most en- 

 tertaining and useful in the volume — treating 

 of the more important works on big game hunt- 

 ing in Africa, India and America. 



Trustworthy information relating to the in- 

 terior of the Labrador peninsula is so scarce 

 that Mr. Low's article will be widely welcomed 

 and will reach a different audience from his 

 much more elaborate official report (Annual 

 Report Geological Survey of Canada, N. S., 

 Vol. VIII., pp. 1-387, Ottawa, 1897). It is a 

 pity that his important notes on big game are 

 marred by antiquated and inaccurate nomen- 

 clature. 



Without attempting to point out the many 

 good things in the book, it may be said that the 

 chapters on Wolves and Bears are intensely in- 

 teresting, and that Mr. Wm. Lord Smith's ac- 

 count of his 'African Shooting Trip,' in com- 

 pany with Dr. A. Donaldson Smith, is an impor- 

 tant addition to the literature of the rapidly 

 diminishing game of the ' Dark Continent. '
