Heredity and Eugenics. By 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 York. "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 questfons which the public is often misled to regard as already and finally settled. 



The Mechanistic Conception of Life. Biological Essays. By 



Jacques Loeb, Head of the Department of Experimental Biology, 



Rockefeller Institute for Medical Research. 238 pages, 12mo, 



cloth ; 6s. net. 



Professor Loeb's experimental researches at the University of Chicago, the 

 University of California, and the Rockefeller Institute for Medical Research, ensure 

 this new collection of his latest conclusions a wide reading. The author's purpose 

 in this book is to discuss the question whether present knowledge gives any hope 

 that hfe may be unequivocally explained in physico-chemical terms. An affirmative 

 answer, he thinks, will necessitate a reconstruction of our social and ethical life on 

 a scientific basis. This volume is a popular presentation of the results of the 

 author's investigation.s, including his successful experiments in chemical fertUizatiou. 

 The wide range of his discussion is seen in the following list of contents : I. The 

 Mechanistic Conception of Life. II. The Significance of Tropisms for Psychology. 



III. Some Fundamental Facts and Conceptions concerning the Comparative 

 Physiology of the Central Nervous System. IV. Pattern Adaptation of Fishes 

 and the Slechanism of Vision. V. On Some Facts and Principles of Physiological 

 Morphology. VI. On the Nature of the Process of Fertilization. VII. On the 

 Nature of Formative Stimulation (Artificial Parthenogenesis). VIII. The Prevention 

 of the Death of the Egg through the Act of Fertihzation. IX. The Role of Salts 

 in the Preservation of Life. X. Experimental Study of the Influence of Environment 

 on Animals.
