[243] In this connection I may refer to Moll's Sexual Life of the Child, to the writings of Dr. Clement Dukes, physician to Rugby School, who fully recognizes the risks of school-life, and to the discussion on sexual vice in schools, started by an address by the Rev. J. M. Wilson, head-master of Clifton College, in the English Journal of Education, 1881-82.
[244] With regard to the importance of the sexual emotions generally and their training, see the well-known book by Edward Carpenter, Love's Coming of Age; Professor Gurlitt ("Knabenfreundschaften," Sexual-Probleme, Oct., 1909) also upholds the intimate friendships of youth, which in his own experience have not had even a suspicion of homosexuality.

[249] Raffalovich, Uranisme et Unisexualité, 1896, p. 16. He remarks that the congenital invert who has never had relations with women, and whose abnormality, to use Krafft-Ebing's distinction, is a perversion and not a perversity, is much less dangerous and apt to seduce others than the more versatile and corrupt person who has known all methods of gratification.
