It also illustrates the variability that is noticeable. Glycogen Glycogen Total extracted. in residue. glycogen.

It is generally admitted, and the view is endorsed by Dr. Paton, that glycogen is the only source of the sugar produced. For the supply of evidence, therefore, on the point in question it does not signify whether it is drawn from the loss of glycogen or gain of sugar. This dif- ference, however, exists. The one is a lengthy and * Lost by breaking of flask. The figures for the check and minced portions serve to illustrate the variability presented in the case of different livers.
