    made, but the flesh of several animals has recently been sub- mitted to analysis. The amount of water averages about 80g, 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: Berzelius. Braconnot. Schlossberger.
