5. Readings in Evolution, Genetics and Eugenics; by 

 Horatio Hackett Newman. Pp. xviii, 523, with 101 figures. 

 Chicago, 1921 (University of Chicago Press). — For supplemen- 

 tary reading in the more general biological sciences, as genetics 

 and organic evolution, it is customary in college courses to assign 

 chapters from a considerable number of standard books. If a 

 sufficient number of copies of the books required could be made 

 available this is without doubt the best way to make the student 

 acquainted with the work of recognized authorities on the sub- 

 ject. But, as a matter of fact, this is feasible only in the case 

 of very small classes. For this reason the author has compiled a 

 book, suitable for a college text, which is composed largely of 

 excerpts from the works to which reference is made. Quotations 

 from some fifty books and papers by forty-four different writers 

 have been cleverly pieced together with the necessary intro- 

 ductory and explanatory^ notes to make a very readable book cov- 

 ering the entire field of genetics, evolution, and eugenics. 



The excerpts are usually sufficiently extensive to give the 

 student a fair example of the best work of the foremost classical 

 and modern biologists as well as of their points of view. The 

 selections appear to be well chosen and the book promises to fill 

 a real need not only in the teaching of biology, but also in stimu- 

 lating the reader to a further acquaintance with the books and 

 writers so auspiciously introduced. w. r. c. 



6. Philosophie des Organischen; von Hans Driesch. Zweite, 

 verbesserte und teilweise umaufgearbeitete Auflage. Pp. xvi, 

 608. Leipzig, 1921 ("Wilhelm Engelmann). This work is based 

 on the author's studies in experimental embrj^ology, hy which 

 he was led to believe that the living organism is more than an 

 aggregate of its parts — that it embraces something that is neither 

 substance nor energy, but a factor peculiar to life which the 

 author terms ' ' entelechy. " This conception of vitalism is 

 invoked in a critical analysis of the processes of development and 

 reproduction and is applied in a discussion of the theories of 

 heredity and evolution, as well as in an examination of the 

 human personality. 



The first five hundred pages, which deal particularly with the 

 science of the organism, have been little changed from the first 

 German edition, which followed the English edition in 1908. 

 But the last hundred pages, bearing on pure philosophy, . have 

 been entirely rewritten to accord with the progress of logic and 

 metaphysics during the past decade. w. r. c.
