SEPT. 19, 1921 POPULAR BOOKS IN SCIENCE 363 



Lewis, Isabel M. Splendors of the sky. 343 pp. (Duflfield and Co., 

 1920.) Popular, accurate, and up-to-date. 



McKready, Kelvin. A beginner's star book. 148 pp. (G. P. Putnam's 

 Sons, 1912.) Many fine illustrations. 



Turner, H. H. A voyage through space. (Society for Promoting Christian 

 Knowledge, London, 1915.) Pleasingly written and reliable. 



The Adolf Stahl lectures in astronomy. 257 pp. (Stanford University 

 Press, California, 1919.) Twelve lectures on modern astronomy by members 

 of the Mount Wilson and Lick Observatory staffs. Accurate, interesting, 

 and nontechnical. 



The properties of matter w^ithout regard to its particular form 



make the subject matter of physics and chemistry. The carbon in 



a star has the same interest to the chemist and the physicist as the 



carbon in a tree-trunk or in a diamond. But it is impossible to write 



a definition that will divide physics from chemistry and still include 



under each all that we commonly understand by the two terms. 



In a general way, the chemist is interested in the composition of things, 



the physicist in their qualities. The titles of a few chemical books 



follow.^ 



Slosson, E. E. Creative chemistry. 311 pp. (Century Co., New York, 

 1920.) A ver}^ interesting and readable book, showing particularly the im- 

 portant place of chemistry in modern industry and in warfare. It is a book 

 abotit chemistry and what it can do, rather than a book of chemistry, but can 

 be recommended to the general and technical reader alike. 



Hendrick, Ellwood. Everyman's chemistry. 374 pp. (Harper and Bros., 

 New York, 1917.) This book is specifically "designed for those who declare 

 that they do not know an3i:hing about the subject." 



Duncan, Robert Kennedy. The chemistry of commerce. 263 pp. (Harper 

 and Brothers, New York, 1907.) An interesting interpretation of various 

 phases of modern industrial chemistry. 



Martin, Geoffrey. Modern chemistry and its wonders. 358 pp. (D. 

 Van Nostrand Co., New York, 1915.) A description in non-technical lan- 

 guage of some of the striking modern advances in chemistry. 



Although the chemist has made contributions to almost every other 

 portion of the field of science, it remains unfortunately true that most 

 of his books are written for specialists and not for the general reader. 

 The "physico-chemical" and "physical" portions of the field of physics 

 and chemistry are not quite so lacking in readable books; the titles 

 of some of these follow : 



SoDDY, Frederick. Matter and energy. 255 pp. (Henry Holt and Co., 

 New York, 1912.) This is one of the best available accounts of fundamental 

 physical and chemical principles. It is very brief and comprehensive, yet 

 authoritative.

 full and well annotated list of books in all branches of chemistry. See Journ. Ind. Eng.
