Abstract
By the use of a special form of osmometer for measuring pressures as low as 1 mm. of water, the mean particle weight of both rabbit liver and of muscle glycogen in 0.1 N CaCl2 has been found to be 2 X 106. Methyl glycogen had a particle weight of 1.36 X 106 in 0.1 N CaCl2 and 3.4 X 103 in benzene. It is considered that this evidence supports the hypothesis that the saccharide units in each particle are bound together by chemical rather than by physical forces.
