GENERAL EDITORS' PREFACE 



THE Editors hope to issue in this series of International Medical 

 Monographs contributions to the domain of the Medical Sciences 

 on subjects of immediate interest, made by first-hand authorities 

 who have been engaged in extending the confines of knowledge. 

 Readers who seek to follow the rapid progress made in some 

 new phase of investigation will find herein accurate information 

 acquired from the consultation of the leading authorities of 

 Europe and America, and illuminated by the researches and 

 considered opinions of the authors. 



Amidst the press and rush of modern research, and the 

 multitude of papers published in many tongues, it is necessary 

 to find men of proved merit and ripe experience, who will 

 winnow the wheat from the chaff, and give us the present 

 knowledge of their own subjects in a duly balanced, concise, 

 and accurate form. 



Major McCay deals with a subject of fundamental importance 

 viz, the amount of protein required in nutrition. From pro- 

 longed inquiries into the habits and physique of the tribes and 

 races of India, he brings forward a body of evidence which proves 

 thata high protein ratio is necessary in child life to produce a 

 virile and active race of men. Major McCay has had splendid 

 opportunities in the material afforded him by the prison dietaries 

 of India, and he has utilized these to the fullest advantage. His 

 final conclusions are in opposition to those of Chittenden, and 

 demand the closest attention of all, and particularly of those 

 who have to deal with dietaries for the young in schools and 



institutions.
