Abstract
IN the course of some estimations of deoxyribo-nucleic acid by Schneider's method1, we observed incidentally that the hot trichloroacetic acid extraction of the tissue removed the collagen almost completely, judged by estimations of hydroxyproline on the hydrolysates of the solubilized and insoluble material.
