The effect of locally administered prolactin on the respiratory activity was formation. There was a fair parallelism between the trends of change of respiratory activity refering to both wet weight and DNA basis. The oxygen consumption of the gland injected with prolactin was significantly higher than that of the control gland. And it increased nearly linearly with the high dose level of administered prolactin. The carbon dioxide production did not follow the oxygen consumption and resulted in a gradual decrease of R. Q. in the glands injected with prolactin ranging from 1 to 5 i. u. However, in the gland injected with 10 i. u. it increased showing a similar trend to that of oxygen consumption and then resulted in the recovery of R. Q. to the level comparable with the control. The R. Q. was always below unity.
