made,, but the flesh of several animals has recently been sub- 

 mitted to analysis. The amount of water averages about 802, 

 and the greater part of the solid residue consists of fibrin ; the 

 other constituents, albumen, hsematoglobulin, fat, extractive 

 matters, lactic acid, the lactates and other salts occur in the 

 expressed juice. The proportions of these constituents have been 

 determined by Berzelius, Braconnot, Schlossberger, Schultz, 

 [and Marchand.] In the flesh of oxen they found :

 Playfair and Bockmann, and found to be identical in its com-
