NOTICES OF BOOKS. 



The Soul of Man. By Dr. Paul Cams. Open Court Publishing 

 Co., 1S91. 4S0 pp., 153 cuts, $3.00. 

 In the Soul of Man Dr. Carus treats of the most salient psychologi- 

 cal problems, presenting them in their connection with philosophy, 

 physical science, including mechanics, physiology, hypnotism, religion, 

 and ethics. Too many writers on psychology are given to metaphysi- 

 cal speculations, and so repel those who have prejudices of their own 

 with reference to the problem of the human soul. This Dr. Carus has 

 studiously avoided and has confined himself to arranging and systema- 

 tizing facts. The statement of his position is made very clear and even 

 pronounced, but the usefulness of the book is by no means restricted to 

 those readers alone who will accept his views. The study of psychology 

 is one of the broadest in the field of science, and, though much neg- 

 lected, is rapidly gaining the prominence it deserves. The present 

 volume, from the mere collection of material it contains, should find its 

 way to all who are interested in the study, however widely their opin- 

 ions may differ from those of the author. 



A Chart of English Literature. By George E. Maclean, Ph. D. 

 Ginn & Co., Boston. (Price 35c.) 

 Experience in the class-room has demonstrated the value of charts. 

 Those who are contemplating a study of the history of English litera- 

 ture will find the present publication of great assistance in their work. 



Gems and Precious Stones. By G. F. Kunz. The Scientific Publish- 

 ing Company, New York, 1890. 4°, 336 pp., 8 colored plates, 36 

 figures. 



The author, George Frederick Kunz, is recognized as the best au- 

 thority the country aftbrds in matters pertaining to gems and precious 

 stones, and the pi"esent volume can but add greatly to his reputation. 

 It certainly fills a want in bringing together a vast amount of interest- 

 ing, descriptive, and historical information never before presented with 

 any similar degree of thoroughness.
