sons of his own sex, is denominated _Uraniaster_. A genuine Urning,
who has put restraint upon his inborn impulse, who has forced himself to
cohabit with women, or has perhaps contracted marriage, is said to be
_Virilisirt_--a virilised Urning.

These outlandish names, though seemingly pedantic and superfluous, have
their technical value, and are necessary to the understanding of
Ulrichs' system. He is dealing exclusively with individuals classified
by common parlance as males without distinction. Ulrichs believes that
he can establish a real natural division between men proper, whom he
calls _Dioninge_, and males of an anomalous sexual development, whom he
calls _Urninge_. Having proceeded so far, he finds the necessity of
distinguishing three broad types of the Urning, and of making out the
crosses between Urning and Dioning, of which he also find three species.
It will appear in the sequel that whatever may be thought about his
psychological hypothesis, the nomenclature he has adopted is useful in
discussion, and corresponds to well-defined phenomena, of which we have
abundant information. The following table will make his analysis
sufficiently plain:--

{ (1) Man or Dioning ... Uraniaster, when
{ he has acquired the
{ tastes of the Urning.
{
The { { Mannling.
Human { (2) Urning { Weibling.
Male { { Zwischen-Urning.
{ { Virilised Urning.
{
{ (3) Uranodioning.
{ (4) Hermaphrodite.

Broadly speaking, the male includes two main species: Dioning and
Urning, men with normal and men with abnormal instincts. What, then,
constitutes the distinction between them? How are we justified in
regarding them as radically divergent?

Ulrichs replies that the phenomenon of sexual inversion is to be
explained by physiology, and particularly by the evolution of the
embryo.[56] Nature fails to complete her work regularly and in every
instance. Having succeeded in differentiating a male with full-formed
sexual organs from the undecided foetus, she does not always effect the
proper differentiation of that portion of the psychical being in which
resides the sexual appetite. There remains a female soul in a male body.
_Anima muliebris virili corpore inclusa_, is the formula adopted by
Ulrichs; and he quotes a passage from the "Vestiges of Creation," which
sugges
