Abstract
WEIDENHAGEN'S theory of the specificity of glucosidases and disaccharases1, as opposed to the theory of specificity of Leibowitz2, depends largely upon the claim that the maltose-splitting factor of taka-diatase is an alpha-glucosidase identical with the sucrose-splitting factor (glucosucrase). According to Leibowitz, on the other hand, taka-maltase is a specific glucomaltase, inert to alpha-methyl-glucoside and distinct from the taka-sucrase.
