A HIGHLY significant seasonal variation in frequency of twin ovulations in Merino ewes was observed by Radford1. In order to determine whether this was correlated with seasonal variation in pituitary gonadotrophin content the surviving ewes from Radford's experiment were later killed—16 in mid-summer (January–February 1958) and 11 in mid-winter (June–July 1958). Each ewe was killed 14 days after œstrus.
