Practical | Physiological Chemistry | [3 lines] | by | Philip B. Hawk, M. S., 

 Ph. D. I [2 lines] | fifth edition, revised and enlarged ] [4 lines] | 

 Philadelphia | P. Blakiston's Son & Co. | 1012 Walnut Street | 1916 | 

 Cloth, pp. i-xiv+ 1-638. 



The great advances in pliysiological chemistry are very well 

 illustrated by the numerous editions of books dealing with this 

 phase of chemistry put out in their attempts to keep abreast 

 of the subject. 



The first edition of Hawk's Physiological Chemistry was pub- 

 lished in 1907 ; the second in 1909 ; the third in 1910 ; the fourth 

 in 1912, followed by reprints of this edition in 1913 and in 1915 ; 

 and the fifth edition is copyrighted in 1916. 



This last edition has been brought up-to-date by thoroughly 

 revising and rewriting the preceding edition and by adding five 

 new chapters. These chapters are: Chapter III on Nucleic 

 Acids and Nucleoproteins, Chapter VIII on Gastric Analysis, 

 Chapter XI on Intestinal Digestion, Chapter XVI on Blood 

 Analysis, and Chapter XXVII on Metabolism. The system of 

 including laboratory directions in the text and the use of black- 

 faced type for the most important and reliable of these tests 

 and methods are valuable features of this book. An examination 

 of this latest edition impresses one with the important part 

 given to the discussion of the function of enzymic activity in 

 the everyday life of the human being. 



The book is printed on good paper, is attractively and well 

 bound, and is well printed. A number of errors have escaped 

 the notice of the proof reader, as, creatinine has been used for 

 creatine (page 508). 



The book is excellent in subject matter and arrangement and 

 is a valuable contribution to this phase of chemical literature, 

 due to Doctor Hawk's wide experience and extensive knowledge 

 of the subject.
