Summary.

The effect of differing lighting schedules upon the timing of the influx of leucocytes into the vaginal smear of the guinea-pig, and hence of ovulation, was examined. The timing of this event was altered following advancement of the light—dark sequence by 12 hr, and implies that the timing of ovulation in this species is influenced by light.
