Abstract
In the normal development of the sparrow testis, a daily period of active spermatogenesis is found between the hours of 2:00 A.M. and 4:00 A.M. This restriction to the hours of darkness appears all the more significant since an inversion of the light period results in the occurrence of mitotic figures during the afternoon hours.
