In sea water that is less acid than Ph spermatozoa live the longer the higher the hydrogen ion concentration. The more inactive the spermatozoa the more slowly their "fertilizing power" diminishes when they are transferred to sea water where they are reactivated. VII. THE RELATION BETWEEN THE ACTIVITY AND THE "FER- TILIZING POWER" OF SPERMATOZOA. "Within a wide limit of egg-concentration the important factors in fertilizing power of sperm suspensions are: (i) concen- tration, (2) time" (Lillie, F. R., 1915, p. 246). The results of this investigation confirm this general conclusion of Lillie's, and.
