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

 ordinarius of Psychology and Natural Philosophy in the University of 

 Lemberg. Published by Ilumbolt 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 Diatomaceae 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 United 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.
