NOTICES OF BOOKS. 



Pantobiblion is an International Bibliographical Review of the 

 world's scientific literature, published monthly. The purpose of this 

 journal is to enable literary and scientific men to be promptly and cor- 

 rectly informed of all cvn-rent scientific literature. It contains a list of 

 all new books published in the different languages of the world, a series 

 of critical articles on all the leading scientific publications, and reviews 

 of current periodical literature. It is published in fifteen different lan- 

 guages, and is one of the most perfect reviews of its kind. 



Mental Suggestion : By J. Ochorowicz, sometime Professor Extra- 

 ordinarius of Psychology and Natural Philosophy in the University of 

 Lemberg. Published by Humbolt Publishing Co., 19 Astor Place, 

 New^ York, in four double numbers. 



The author, being a learned physiologist and physicist as well as a 

 psychologist, is in every way competent to treat the subject. It is a 

 work original in its method and point of view, and possesses great 

 charm of literary style, together with simplicity and clearness of expres- 

 sion. It is unquestionably the most complete work on hypnotism ever 

 written. 



NOTES. 



To those interested in the Diatomacea; we commend an article pub- 

 lished in the November number of the American Journal of Science^ 

 by Arthur M. Edwards, M. D., entitled, " Report of the Examination 

 by Means of the Microscope of Specimens of Infusorial Earths of the 

 Pacific Coast of the LTnited States." The trend of the paper is not to 

 the determination of species, but to geological formation and the origin 

 of deposits. 



A class in Bacteriology was opened at Georgetown College on Nov. 

 5th.
