to form a just
conception of clergymen, doctors, or lawyers by studying them exclusively
in prison, and this remains true even although a much larger proportion of
prostitutes than of members of the more reputable professions pass through
prisons; that fact no doubt partly indicates the greater abnormality of
prostitutes.

It has, of course, to be remembered that the special conditions of the
lives of prostitutes tend to cause in them the appearance of certain
professional characteristics which are entirely acquired and not
congenital. In that way we may account for the gradual modification of the
feminine secondary and tertiary sexual characters, and the appearance of
masculine characters, such as the frequent deep voice, etc.[189] But with
all due allowance for these acquired characters, it remains true that such
comparative investigations as have so far been made, although
inconclusive, seem to indicate that, even apart from the prevalence of
acquired anomalies, the professional selection of their avocation tends to
separate out from the general population of the same social class,
individuals who possess anthropometrical characters varying in a definite
direction. The observations thus made seem, in this way, to indicate that
prostitutes tend to be in weight over the average, though not in stature,
that in length of arm they are inferior though the hands are longer (this
has been found alike in Italy and Russia); they have smaller ankles and
larger calves, and still larger thighs in proportion to their large
calves. The estimated skull capacity and the skull circumference and
diameters are somewhat below the normal, not only when compared with
respectable women but also with thieves; there is a tendency to
brachycephaly (both in Italy and Russia); the cheek-bones are usually
prominent and the jaws developed; the hair is darker than in respectable
women though less so than in thieves; it is also unusually abundant, not
only on the head but also on the pudenda and elsewhere; the eyes have been
found to be decidedly darker than those of either respectable women or
criminals.[190]

So far as the evidence goes it serves to indicate that prostitutes tend to
approximate to the type which, as was shown in the previous volume, there
is reason to regard as specially indicative of developed sexuality. It is,
however, unnecessary to discuss this question until our anthropometrical
knowledge of prostitutes is more extended and
