the stronger institutions have long since expanded the sec- 

 ond year course in chemistry into a very creditable course 

 of physiological chemistry, beginning with an investiga- 

 tion of foodstuffs, following this with qualitative and 

 quantitative work on the chemistry of digestion, and de- 

 voting the last semester of the second year to the analysis 

 of urine. The best laboratory manuals on the subject are : 

 Long's " Laboratory Manual of Chemical Physiology," 

 Colegrove& Co., Chicago, 1895; Stirling's "Practical Phys- 

 iology" (first part); Halliburton's "Essentials of Chemical 

 Physiology"' Longmanns, Green & Co., 1893. The phy- 

 siological library should contain also : " Text-book of 

 Chemical Physiology and Pathology," Halliburton, Long- 

 manns, Green & Co., 1891 ; "Physiologische Chemie," 

 Bunge, Vogel, Leipzig, 1894 ; " Lehrbuch d, physiologisch, 

 Chemie," Neumeister, Gustav Fischer, Jena, 1893; "Phy- 

 siological Chemistry," Hammarsten, Wiley & Sons, New 

 York, 1893 ; " Physiological Chemistry of the Animal 

 Body, "Gamger, Macrnillan, 1893; "Chemical Physiology 

 and Pathology," Hoppe-Seyler.
