e doubt that inverted women frequently tend to show minor
anomalies of the piliferous system, and especially slight hypertrichosis
and a masculine distribution of hair. Thus in a very typical case of
inversion in an Italian girl of 19 who dressed as a man and ran away from
home, the down on the arms and legs was marked to an unusual extent, and
there was very abundant hair in the armpits and on the pubes, with a
tendency to the masculine distribution.[169] Of the three cases described
in this chapter which I am best acquainted with, one possesses an
unusually small amount of hair on the pubes and in the axillae
(oligotrichosis terminalis), approximating to the infantile type, while
another presents a complex and very rare piliferous heterogeny. There is
marked dark down on the upper lip; the pubic hair is thick, and there is
hair on toes and feet and legs to umbilicus; there are also a few hairs
around the nipples. A woman physician in the United States who knows many
female inverts similarly tells me that she has observed the tendency to
growth of hair on the legs. If, as is not improbable, inversion is
associated with some abnormal balance in the internal secretions, it is
not difficult to understand this tendency to piliferous anomalies; and we
know that the thyroid secretion, for instance, and much more the
testicular and ovarian secretions, have a powerful influence on the hair.

Ballantyne, some years ago, in discussing congenital
hypertrichosis (_Manual of Antenatal Pathology_, 1902, pp. 321-6)
concluded that the theory of arrested development is best
supported by the facts; persistence of lanugo is such an arrest,
and hypertrichosis may largely be considered a persistence of
lanugo. Such a conclusion is still tenable,--though it encounters
some difficulties and inconsistencies,--and it largely agrees
with what we know of the condition as associated with inversion
in women. But we are now beginning to see that this arrested
development may be definitely associated with anomalies in the
internal secretions, and even with special chemical defects in
these secretions. Virile strength has always been associated with
hair, as the story of Samson bears witness. Ammon found among
Baden conscripts (_L'Anthropologie_, 1896, p. 285) that when the
men were divided into classes according to the amount of hair on
body, the first class, with least hair, have the sm
