To the Editor:
—In The Journal, September 5, page 627, synopsis of Dr. Jennie G. Drennan's paper on the "Physiologic Generation Cycle of Woman," the following statement is made:In mammals and primitive woman ovulation occurs at distinct periods of the year and at no other time. Mating with the primitive woman was much like that of the brute creation now; as soon as she was sexually mature she married and entered on the physiologic cycle of a mammal, etc.It has seemed to me in the course of my studies that ovulation depended more on the abundance of food at the command of woman than any other cause, regardless of the stage at which she lived in the history of civilization. I wish Dr. Drennan would state the grounds on which she bases her statement, for it is a very interesting scientific fact
