Artificial Parthenogenesis and Fertilization. By Jacques 

 LoEB, Member of the Rockefeller Institute for Medical Research. 

 318 pages, 12mo, cloth; 10s. net. 



This new work presents the first complete treatment of the subject of artificial 

 parthenogenesis in English. Professor Loeb published four years ago a book in 

 German under the title Die ckemische Entivirliungserrcgung des tieriichen Eies. 

 Mr W. O. R. King, of the University of Leeds, translated the book into English, 

 and tho translation has been revised, enlarged, and brought up to date by Professor 

 Loeb. It gives, as the author says in the preface, an account of the various methods 

 by which mifertilized eggs can be caused to develop by physico-chemical means, 

 and the conclusions which can be drawn from them concerning the mechanism by 

 which the spermatozoon induces development. Since the problem of fertihzation is 

 intimately connected with so many different problems of physiology and pathology, 

 the bearing of the facts recorded and discussed in the book goes beyond the special 

 problem indicated by the title. 



British Medical Journal. The subject of the book is an analysis of the mechanism by 

 which the male sex cell — the spermatozoon — causes the animal egg to develop. The 

 author has gained a world-wide reputation for his achievements in artificial fertilization, 

 and this work shows how, according to his observations, the action of weU-known chemical 

 and physical agencies may be substituted for that of the living spermatozoon. 



Heredity and Eugenics. B}' John M. Coulter, William E. 

 Castle, Edward M. East, William L. Tower, and Charles B. 

 Davenport. 312 pages, 8vo, cloth ; 10s. net. 



Five leading investigators, representing the University of Chicago, Harvard 

 University, and the Carnegie Institution of Washington, have contributed to this 

 work, in which great care has been taken by each contributor to make clear to the 

 general reader the present position of evolution, experimental results in heredity in 

 connection with both plants and animals, the enormous value of the practical 

 application of these laws in breeding, and human eugenics. Technicalities of 

 language have been avoided, and the result is an instructive and illuminating 

 presentation of the subject for readers untrained in biology as well as for students.

British Medical Journal. Those who are desirous of arriving at an estimate of the 

 present state of knowledge in all that concerns the science of genetics, the nature of 

 the experimental work now being done in its various departments, ...and the prospects, 

 immediate or remote, of important practical applications, cannot do better than study 

 "Heredity and Eugenics." 



The Nation, New Xork. "Heredity and Eugenics" may be heartily recommended to 

 readers seeking, as beginners, to get in touch with the discussion of these subjects. ...In 

 most of the lectures there is an admirable reserve, not to say skepticism, in the treatment 

 of large questions which the public is often misled to regard as already and finally settled.
