THE QUARTERLY REVIEW OF BIOLOGY 



there is this further to be said that, after 

 all, the lines of the hand are a priori no 

 more inherently unpromising, considered 

 as anatomical stigmata of constitutional 

 anomalies, than are some of the characters 

 seriously discussed in standard medical 

 treatises on this subject. 



EINSTELLUNG ZUR RONTGENO- 



LOGIE. Eine Untersuchung uber die Ein-

 Praxis, Forschung und Unterricht.

 One of the outstanding figures in 

 roentgenology, a man who has watched 

 the development of the speciality from 

 its beginnings in 1895 to i ts enormous 

 usefulness in 19x6, feels the need for 

 taking stock. The growth of the subject 

 has been so rapid that there is much 

 chaos and much need for finding out what 

 is true and useful and what is not. He 

 regrets that articles on the theory and 

 practice of roentgenology are scattered 

 through many books and journals where 

 one would hardly expect to find them. 

 They are written often from the points of 

 view of many specialists who only 

 incidentally are roentgenologists. The 

 spread of interest in the subject is revealed 

 also in the field of teaching, where it is 

 hard to know what to do with students; 

 should they get most of their knowledge 



of the roentgen ray in one department or 

 should they pick it up here and there in 

 the departments of physics, medicine, 

 gastroenterology, surgery, gynecology, 

 urology, dermatology and orthopedics? 

 Similarly, what should be the training of 

 the specializing roentgenologist? Should 

 he ever be a layman? These and many 

 other problems of great interest to Ameri- 

 can physicians are ably discussed. Unfor- 

 tunately, Holzknecht's German may prove 

 hard going for some. 



CONTRIBUTION METAPHYSIQUE a 



la Methode Experimentale . 

 By Louis Devos. Georges Frere 



ix. 50 francs Tourcoing 



6 x 9I; 56 (paper) 

 This booklet is written with such an 

 enormous frugality of words that, frankly, 

 we have not been able quite to grasp the 

 point — at least not firmly. One thing, 

 however, seems clear; that at the present 

 stage of the development of the author's 

 theory it concerns the physicist more than 

 it does the biologist.
