=The Metatropic Man= prefers tall, strong, powerful women, often of a different nationality or race, at times, women with some physiological handicap, lameness or deformity (the French philosopher Descartes was attracted to women suffering from strabism). He generally selects a woman older than himself, either very intellectual or very low ethically. In one case he is dominated by her mental superiority, in the other he feels that he is sacrificing his principles or his social standing. Professional or business women appeal to him especially. He is often a shoe fetishist. Clothing which denotes power, authority, impresses him. =The Metatropic Woman= seeks feminine, beardless men, with perhaps a good head of long hair (poets, artists). Madame Dudevant, the French novelist, adopted the masculine name George Sand and had affairs with two sickly artists, Musset, the poet, and Chopin, the composer. The metatropic woman is often a professional or business woman who, in her love relation, assumes a very independent, dictatorial attitude to men. She favors young men whom she can dominate better. In what Hirschfeld calls metatropists, we recognise parent-fixation men and women, obsessed by a conscious or unconscious incest fear, a complication which has been discussed in another chapter. Krafft-Ebing and Albert Eulenburg classify metatropic men with masochists (see Chapter XX) and metatropic women with sadists (see Chapter XIX). =Dr. Steinach's Experiments= show the close relationship between homosexualism and the secretions of the interstitial cells of the genital glands. After castrating young rats which, after the operation, remained in an infantile stage of development, Steinach transplanted into their inguinal region male or female gonads. Males into which female gonads had been implanted, developed all the physical characteristics and all the mannerisms of the female, paid no attention to females at mating time and, on the contrary, attracted the rutting males and were attracted to them. Castrated females in whose body he implanted testicles, showed the hardier hair growth of males, tried to mate with females and remained indifferent to males. Prof. Brandes, director of the Zoological Garden in Darmstadt, has repeated those experiments on deer with identical results. The female in which testicles were implanted behaved like a male and grew antlers. The male's mammary glands grew very fast after the implantation of female gonads. It is said that Steinach has successfully transformed homosexuals into normal men but the last statement of his on the "Histology of the Gonads in homosexual Men," (Vol. 46, No. 1, Archiv für Entwickelungsmechanismus der Organismen) contains no mention of such results.
