Abstract
Succinic and glutamic dehydrogenase activities were measured on tissues of three species of tadpoles during the course of the metamorphosis, Glutamic dehydrogenase of the tail muscle of Rana catesbiana and succinic as well as glutamic dehydrogenase of the whole tail tissue of Rana japonica decreased prior to the beginning of the resorption of the tail, With eviscerated whole body of the Bufovulgaris formosus, the decrease in these enzymes took place at a similar stage followed by no marked change in proteolytic enzyme activity.
