Handbook of biochemical methods, edited by E. Abderhalden {Handhuch 

 der Biochemischen Arbeitsmethodcn. Berlin and Vienna, 1913, vol. 7, pp. 

 XXVIII-^912, figs. 198).— This is the seventh volume of this work (E. S. R.. 29, 

 p. 40S), and contains the following chapters: The living animal material for 

 biochemical investigations (selecting, obtaining, and keeping under various con- 

 ditions) ; the use of secretin for obtaining pancreatic juice; the detection and 

 preparation of methylated amino acids (betains) in animal and vegetable tissues ; 

 preparation of some substances of biochemical importance from molasses and 

 molasses slops; the most important methods for examining foods and condiments 

 (a very extensive chapter) ; the technique of investigating the respiratory 

 gaseous exchange in healthy and diseased subjects; the precipitins and methods 

 of precipitation; the methods of investigating the biochemically important 

 actions of light ; microscopic technique ; some rapid methods for the examination
