tion has been greatly enlarged, and embodies several novel 

 features. Among the latter may be mentioned a description of 

 the most important drugs indigenous to North America, and 

 also a list of remedies classified according to their zoological or 

 botanical derivation. The work gives the essential physical, 

 histological and chemical characters of the organic drugs, thus 

 rendering the work also a useful and reliable guide in business 

 transactions. It embraces all the drugs recognized by the U. 

 S. and British Pharmacopoeias, together with important old 

 drugs, now imofficinal. The microscopical characteristics are 

 unusually full. The work will have a large and ready sale.

This is one of the u Manuals for Students of Medicine " as 

 issued by the well known Philadelphia firm. The work em- 

 braces the elementary facts and principles of physics with their 

 physiological applications. There is also some detailed descrip- 

 tion of physical apparatus and methods as adapted to physio- 

 logical purposes. The book is one calculated to enable the 

 student to take it to the laboratory and, with its aid, set up and 

 work out the experiments for himself.

In this interesting little volume we have a discussion of the 

 evolution and relations of the mind and body of* man and ani- 

 mals. The author grapples the question of the physio-chemical 

 basis of psychological phenomena with great force and tact. 

 The intention of the work appears to be to elaborate a mental 

 science which will reconcile the observations of anatomists, 

 psychologists and pathologists with direct reference to the more 

 intelligent treatment of insanity. We fear that Dr. Clevenger 

 will be misunderstood by some statements made in the second 

 chapter concerning spontaneous generation ; perhaps, however, 

 he believes in it. For us, we simply believe with Dr. Dal- 

 linger that there cannot be found a scientist of to-day who 

 accepts the doctrine.
