In an analysis of the menstrual histories of 800 consecutive women in their private practice, Lintz and Markow attempt to show that environment has very little if any effect on the age of onset of menstruation. They compared the histories of girls roared in small towns, small cities, and the Iargcr cities and found the average age of onset was practically the same. They conclude that the cndocrinologic heritage more t,han any other factor determines the age of onset. IV.
