The author, in using Berzelius's classification of "metals" and "metal- 

 loids," Berthollet's "types;"' and other portions of past chemical literature, 

 is introducing a conception of the science that, while fundamentally 

 useful in its clay, has now passed away. 



Some very useful features, such as the physiological effects of com- 

 pounds and the. study of toxins, are found in the book, and the proteins 

 are studied according to the latest classification. Useful data are included 

 under the heading of "Food and Diet," which, as a rule, are scattered 

 in books on Physiology and Hygiene. The clinical examinations in- 

 clude Digestive Secretions, Milk and Urine. The analytical methods 

 are briefly and conscientiously explained. 



In my opinion, the medical student had better spend a sufficient amount 

 of money to build up for himself a library of special manuals covering 

 the subjects dealt with in this book. »
