at many cases of frigidity in matrimony, unhappy unions, and
so forth, are attributable to the peculiar diathesis of the male--or it
may be, of the female--in these marriages. They are distinguished from
his previous class of "acquired" inversion by the fact that the latter
start with instincts for the other sex, which are gradually obliterated;
whereas the psychical hermaphrodites commence life with an attraction
towards their own sex, which they attempt to overcome by making demands
upon their rudimentary normal instincts. Five cases are given of such
persons.[32]

In the next place he comes to true homosexual individuals, or Urnings in
the strict sense of that phrase. With them there is no rudimentary
appetite for the other sex apparent. They present a "grotesque" parallel
to normal men and women, inverting or caricaturing natural appetites.
The male of this class shrinks from the female, and the female from the
male.[33] Each is vehemently attracted from earliest childhood to
persons of the same sex. But they, in their turn, have to be subdivided
into two sub-species. In the first of these, the sexual life alone is
implicate; the persons who compose it do not differ in any marked or
external characteristics from the type of their own sex; their habits
and outward appearance remain unchanged. With the second sub-species the
case is different. Here the character, the mental constitution, the
habits, and the occupations of the subject have been altered by his or
her predominant sexual inversion; so that a male addicts himself to a
woman's work, assumes female clothes, acquires a shriller key of voice,
and expresses the inversion of his sexual instinct in every act and
gesture of his daily life.

It appears from Krafft-Ebing's recorded cases that the first of these
sub-species yields nearly the largest number of individuals. He
presents eleven detailed autobiographies of male Urnings, in whom the
_vita sexualis_ alone is abnormal, and who are differentiated to common
observation from normal men by nothing but the nature of their amorous
proclivities. The class includes powerfully developed masculine beings,
who are unsexed in no particular except that they possess an inordinate
appetite for males, and will not look at females.

As regards the family history of the eleven selected cases, five could
show a clear bill of health, some were decidedly bad, a small minority
were uncertain.
