rivals. He endures more than would be possible in his ordinary physical state. Then come the care of the young and the long flights for water and food during the drought of the summer. After the molt, autumn finds him once more in flock, and with the first frosts he is off again to the South. In the wild state, rut is the capstone of perfect physical condition." (A. W. Johnstone, "The Relation of Menstruation to the other Reproductive Functions," American Journal of Obstetrics, vol. xxxii, 1895.)

      Wiltshire ("Lectures on the Comparative Physiology of Menstruation," British Medical Journal, March, 1888) and Westermarck (History of Human Marriage, Chapter II) enumerate the pairing season of a number of different animals.

      With regard to the breeding seasons of monkeys, little seems to be positively known. Heape made special inquiries with reference to the two species whose sexual life he investigated. He was informed that Semnopithecus entellus breeds twice a year, in April and in October. He accepts Aitcheson's statement that the Macacus rhesus, in Simla, copulates in October, and adds that in the very different climate of the plains it appears to copulate in May. He concludes that the breeding season varies greatly in dependence on climate, but believes that the breeding season is always preserved, and that it affects the sexual aptitude of the male. He could not make his monkeys copulate during February or March, but is unable to say whether or not sexual intercourse is generally admitted outside the breeding season. He quotes the observation of Breschet that monkeys copulate during pregnancy.
