310 Scientific Intelligence. 



giving a course in vertebrate anatomy the comparative study of 

 the organ systems has in large measure supplanted the older 

 study of the entire anatomy of selected types. By the newer 

 method the student more readily grasps the significance of mor- 

 phological details and secures a more substantial conception of 

 the course of evolution. 



To accompany such a laboratory study this manual is eminently 

 fitted. One of the primary objects of the book is to compel the 

 student to become self-reliant in his work, and the directions and 

 descriptions are so explicit that he no longer has an excuse for 

 calling on the instructor for an unreasonable amount of assist- 

 ance. This is certain to be of benefit both to, student and 

 instructor ; to the former because of the superior mental discipline 

 involved, and to the latter because of a relief from constant 

 appeals for help. The book has already met the test successfully.

4. The Vitamins; by H. C. Sherman and S. L. Smith. Pp. 

 iii, 273 pp. New York, 1922 (The Chemical Catalog Company. 

 Price, $4.00). — This is an excellent review of a subject which has 

 acquired pronounced interest for the biochemist, the physiologist, 

 the biologist, the bacteriologist, the physician, the agriculturalist, 

 and the food manufacturer during the past decade. It is not an 

 easy task to prepare a critical summary of the history and status 

 of a new chapter in science that already encompasses an enormous 

 literature which is growing at a rapid rate ; but Sherman and 

 Smith have succeeded. The volume is certain to become an 

 almost indispensable reference book on the subject of vitamins. 

 It presents encyclopedic information in a readable style. 

 Although the book includes elaborate compilations of data about 

 vitamins, there is scarcely a page that does not help to awaken an 

 interest in the newer aspects of food values or point to the prob- 

 lems raised thereby. l. b. m.

Catalogue of the fossil Bryozoa (Polyzoa) in the Department 

 of Geology. The Cretaceous Bryozoa. Vol. Ill, the Cribri- 

 morphs, part 1; by W. D. Lang. Pp. ex, 269, with 115 text 

 figures and 8 plates. — This work has been carried along the lines 

 laid out by Dr. J. W. Gregory. The volume is divided into two 

 sections: Part I includes the Introduction, which is (A) Biologi- 

 cal; (B) Terminological; (C) Historical. Part II is Systematic, 

 giving (1) the characters of the families; (2) doubtful species; 

 (3) the systematic account (pp. 16-255). Two indexes close the 

 volume. The excellent drawings for the plates have been made 

 by Miss Gertrude M. Woodward ; those of the text figures mostly 

 by the author.
