Those whose interest in popularizing science leads them to 

 an acquaintance with books which summarize scientific knowl- 

 edge for general readers will need no recommendation of a new 

 book by Professor J. Arthur Thomson, of Aberdeen, for a 

 book by the gifted author of Studies of Animal Life, Heredity, 

 Outlines of Zoology and Science of Life is sure to be readable 

 literature and reliable science. Darwinism and Human Life is 

 a series of lectures which explains the problems which Darwin 

 set himself to solve, incficates the progress which has been made 

 since Darwin's day, and finally suggests how Darwinism touches 

 everyday life. Its chapters are as follows : I, What We Owe to 

 Darwin; H, Web of Life; HI, Stuggle for Existence; IV, Raw 

 Materials of Progress ; V, Facts of Inheritance ; VI, Selection, 

 Organic and Social. The human application in the latter part 

 of the book will be most interesting to general readers who are 

 already acquainted with the main facts of evolution. The 

 Appendix contains an excellent list of representative books on 

 Darwinism. 



Evolution, by Geddes and Thomson, is one of the most 

 readable existing books for general readers, and presents the 

 facts, causes and bearings of evolution in eight chapters, as 

 follows: I, Evidences from Explorer and Palaeontologist; II, 

 Evidences from Anatomist, Embryologist and Physiologist; III, 

 Great Steps in Evolution; IV, Variation and Heredity; V, 

 Selection ; VI, Organism. Function and Environment ; VII, 

 Evolution Theories in their Social Origins and Inter- Actions ; 

 VIII, Evolution Process Once More Reinterpreted. The absence 

 of illustrations makes the book somewhat more difficult reading 

 than Romanes's Darwin and After Darzvin, Volume I, but it 

 seems probable that most of this new book would be intelligible
