That this series of papers is fundamentally important for the 

 science of animal behavior is obvious.

Hornaday, Wm. T. The American Natural History. Xe7i< York, Scribner's 

 Sons, 1904, XXV -\- 449. 



A popular natural history which C(intains much interesting and 

 valuable information concerning American animals. The work is 

 splendidly illustrated and pleasingly written. It should be of consid- 

 erable value as a means of arousing interest in animals and stimulating 

 to a study of their characteristics. r. m. v. 



'Cohn, Paul. Gemiitserregungen und Krankheiten. Berlin, I'ogel und Kreien- 

 brink, 1903, pp. 148. 



The book contains a study of the nature and localization of emo- 

 tions. The first part deals with the physiological accompaniments of 

 feelings and emotions, the second with their pathological effects, and 

 the third gives hints for a prophylaxis. The author adopts the theory 

 that all feelings can be reduced to organic sensations of the body and 

 of the brain. He professes a general disdain for all previous work, 

 which he claims to be too speculative, and he acknowledges Nietzsche 

 as his only predecessor. None of the modern inquiries into the nature 

 of feelings is mentioned, and the experimental studies of the physio- 

 logical influence of feelings are utterly ignored. f. m. urban. 



Putnam, J. J. The Value of the Physiological Principle in the Study of Neu- 

 rology. Am. Medicine, 1904, 8, No. 25, 10^1-1056. 



Dr. Putnam's address before the section of Neurology of the In- 

 ternational Congress of Arts and Sciences at St. Louis is published in 

 full in American Medicine, as cited above, and simultaneously in the 

 Boston Medical and Surgical Journal. The contrast is sharply drawn 

 between Virchow's "Anatomical Principle in the Study of Disease" 

 and the attempt to localize morbid processes on the one hand, and on 

 the other hand the morbid process as maladjustment. "No anatomical 

 research can pierce to the secret of broken coordinations, and yet it is 

 in these that a great part of disease begins, or comes eventally to con- 

 sist." "Every organism, whether we call it diseased or well, presents 

 itself to our view as a web of interwoven 'energies,' which in order to 

 study them by anatomic means, we must break artificially into frag- 

 ments that have, in reality, no correspondingly separate existence." 

 This is a point of view which has its application in normal function, as 

 well as in pathology. c. j. h.
