 Including a Digest of the Report of the Referee 

 Board of Scientific Experts on the Influence of 

 Aluminum Compounds on the Nutrition and 

 Health of Man. 



By Ernest E. Smith. Paul B. Hoeber, Inc. 



$7.00 6x9; xii + 378 New York 



For anyone interested in the composi- 

 tion and value of food stuffs this book 

 should prove interesting. The author 

 discusses the occurrence of aluminum in 

 the various food stuffs and the effects of 

 their use. Many of his own researches 

 are given as well as the data and conclu- 

 sions of others. At the end of a chapter 

 of discussion of the material the opinion is 

 expressed that alum baking powders are no 

 less wholesome than any other variety. 

 The terrific battle now waging between 

 the Baking Powder Boys has at least the 

 value to the world in general that it has 

 led to compilations of the pertinent 

 physiological and biochemical literature 

 regarding the effects upon living things of 

 aluminum compounds and tartaric acid and 

 its derivatives, likely to be of considerable 

 use to biologists in general. 



Fundamentally they are independent, but 

 are coordinated by the internal circulation 

 of the heart. He draws extensively in 

 support of his claims on evidence from 

 pathological conditions, as revealed by the 

 electrocardiogram and as shown by post- 

 mortem examination. Whether his theory 

 is sound is a question for specialists to 

 decide. 



THE BASIS OF SENSATION. The Action 

 of the Sense Organs. 

 By A. D. Adrian. 



W. W. Norton and Co., Inc. 

 $x.5o 5^ x 8f ; IZ2. New York 



With the development of the vacuum 

 tube amplifier it has become possible to 

 investigate minute changes in electric 

 phenomena with a high degree of accuracy. 

 The present volume gives an account of 

 Dr. Adrian's investigations on the action 

 of the sense organs, as revealed by the 

 electrical changes set up in the nerves . It 

 is an interesting and instructive account of 

 research in a particular field; the author 

 has deliberately confined himself to his 

 own field, and has not attempted any 

 general review or summary of other work 

 on the sense organs. 



LE MECANISME DU CCEUR ET SES 

 ANOMALIES. Etudes Anatomiques et 

 Electrocardiographiques . 



By Emile Geraudel. Masson et Cie

6f x 3co|; vii + 185 (paper) 

 The purpose of this book is to develop a 

 new theory of the causes of the heart beat. 

 The author holds that structurally the 

 bundle of His and the sino-auricular node 

 are identical; and that accordingly their 

 functions should be the same. He con- 

 siders them both as motor centers, the one 

 for the ventricle, the other for the auricle.

This is a readable little book well 

 designed to give to intelligent laymen 

 some idea of the basic principles in 

 dietetics. 



On page 13, we view with alarm the 

 fact that "Cannibalism is certainly more 

 desirable as regards proteins than is a 

 strict diet of vegetarianism. The cannibal
