1. Glycolytic and respiratory activities of finely teased testes of rats were measured manometricaly in the progress of age. A remarkable decline of both activities was observed before the 60th day of age, and thereafter remained at a constant level as shown in figures 1 and 2. Changes of respiratory quotient (R. Q.) of testes were not remarkable throughout all ages examined.<BR>2. Measurment of the activity of the endogenous cytochrome <I>C</I>, cytochrome oxidase system was carried out wirh <I>P</I>-phenylenediamine as a reducing substance for cytochrome <I>C</I>, using homogenized testicular tissue, prepared in isotonic KCl solution. The results are shown in figure 3.<BR>An increase of the activity was found at the stage where the testis attained the weight of 300mg, in other words the "sperm head" began to appear.
