 Institute of St. Louis and The Gradwohl Biological Labora- 

 tories, St. Louis, and A. J. BLAIVAS, Assistant in the same; 

 Sometime Assistant in Pathological Chemical Laboratories of

 This monogram by Gradwohl and Blaivas gives in fullest de- 

 tail the methods of blood and urine chemistry along lines of 

 micro-chemical investigation originated by Folin and Denis, 

 Benedict and Lewis, Myers and Fine. Attention is paid to the 

 needs of the beginner in these analyses in that every test is 

 fully described, the apparatus used is fully illustrated, with 

 colored plates of the standard solutions used in the colorimeter 

 of Hellige or Duboscq. The first part of the book deals entirely 

 with technic. The second half of the book is devoted to the 

 interpretation of the data obtainable by blood chemical meth- 

 ods. This part of the work represents a careful review of the 

 entire literature on this question, taking up the matter of 

 diabetes mellitus, renal diabetes, acidosis, the distinction be- 

 tween gout and rheumatism, and early chronic interstitial 

 nephritis, and lastly the question of the interpretation of blood 

 chemistry of the chronic nephritides.

 titioner. Introduction by VICTOR C. VAUGHAN, M.D.,

 Here at last is the book for which the doctors have been wait- 

 ing, the book which will enable them to make their own labora- 

 tory diagnoses. It will relieve them of the mortifying and ex- 

 pensive necessity of sending away their specimens to get some 

 better posted man to tell them what is the matter with their 

 patients. It is a book every physician should have. Southern 

 Medical Journal.
