BOOK REVIEWS. 



The Physician's Leisure Library, Detroit; Geo. S. Davis. 



Three more numbers of this excellent series have been received, 

 viz.: The Physiological, Pathological and Therapeutic EfPects of 

 Compressed Air, by Albert H. Smith, M. D. ; On the Determination 

 of the Necessity for Wearing Glasses, by D. B. St. John Roosa, M. 

 D. ; and, Granular Lids and Contagious Ophthalmia, by W. F. Mit- 

 tendorf, M. D. 



The study of the effects of compressed air is comparatively new 

 and Dr. Smith, as surgeon to the New York Bridge Co., has had pe- 

 culiar opportunities for its prosecution. The study of the physio- 

 logical and pathological effects produced in men when subjected to 

 great atmospheric pressure is a necessary step to the determination 

 of the therapeutic value of such a pressure artificially produced. Dr. 

 Smith's little monograph well repays careful reading. The volumes 

 on diseases of the eye are timely and will afford excellent guides to 

 the practitioner removed from easy access to the specialist. 



Primer of the Clinical Microscope, by Ephraim Cutter, M. D., Boston, 

 Cliarles Stodder, 1879. pp. 24. Price 50 cts. 

 This little work although first published eight years ago, con- 

 tains much valuable information for the beginner, upon which time 

 and progress can have little effect.
