SEPT. 19, 1921 POPULAR BOOKS IN SCIENCE 355 



Mason, O. T. The origins of invention. 419 pp. ("Contemporary- 

 Science Series," Walter Scott, London, 1895.) Although old, this book is 

 thoroughly reliable and will remain authoritative for decades to come. It 

 is readable and entertaining, and at the same time based on a wide knowledge 

 of anthropology and ethnology. 



Mason, O. T. Woman's share in primitive culture. 295 pp. (D. Appleton 

 and Co., New York, 1894.) Like the preceding book by the same author, 

 this work remains a standard. It will be particularly welcome to readers 

 who have been irritated by the irresponsible pseudo-science that is sometimes 

 written about the relative status of the sexes in primitive, as compared with 

 modern, society. 



OsBORN, Henry Fairfield. Men of the Old Stone Age, their environment, 

 life and art. 545 pp., 268 illustr., 33 pp. of bibliography and index. (Charles 

 Scribner's Sons, New York, 1915.) This book is a popular synthesis of the 

 findings and opinions of many specialists, including the author himself, 

 in the fields of archeology', paleontology, geology, anthropology and primitive 

 art. 



Haddon, a. C. The study of man. 410 pp. (G. P. Putnam's Sons, 

 New York, 1898.) A reliable and readable work by one of the foremost 

 ethnologists and anthropologists of Great Britain. It deals interestingly 

 with the distribution of Man and his varieties over the Earth's surface. 



KiDD, Dudley. Savage childhood, a study of Kafir children. 314 pp., 

 32 illustr. from photographs. (Adam and Charles Black, London, 1906.) 

 This book is less general than the preceding but it is particularly attractive. 

 The games, stories and songs of Kafir children as well as Kafir customs per- 

 taining to children are described in a charming and instructive manner 

 The book is artistic rather than scientific but is a distinct addition to popular 

 knowledge of anthropology and ethnology. 



Hough, Walter. The Hopi Indians. 265 pp. (Torch Press, Cedar 

 Rapids, Iowa, 1915.) This is one of the best examples available of descriptive 

 anthropology applied to a particular group. It is entertainingly written, 

 and the author's long experience in the field is a guarantee of its accuracy. 



McCoLLUM, E. V. The newer knovuledge of nutrition. 199 pp. (The 

 Macmillan Co., New York, 1919.) This book contains an authoritative, 

 non-technical statement of the principles underlying proper human nutrition 

 as developed from a great number of experiments and observations, some 

 of the experiments having been carried out by the author and described by 

 him in an interesting way in the book, with illustrations. The literature 

 on the subject of nutrition has been survey^ed and condensed reference is 

 made to this extended field. 



Sherman, H. C. Food products. 594 pp. (The Macmillan Company, 

 New York, 1918.) The chemistry, physiology, availability and economics 

 of human foodstufi's are authoritatively discussed in essentially nontechnical 

 language. 



Man shares with every other member of the animal and vegetable 

 kingdoms that remarkable capacity, still a mystery to every investi- 

 gator, whether biologist, chemist, or physicist — the capacity of re- 

 producing his kind and handing down his qualities to his descendants 

 The following books on heredity are standard works in this field
