Nymphomaniac women should not be permitted to
marry or to run around loose, but should be confined to institutions
in which they can be subjected to proper treatment.

=Harelip=

This is a congenital defect consisting in a notch or split in the
upper lip. It is due to defective development of the embryo and is as
a rule found in association with cleft palate. Probably hereditary,
but is not common and is not of much importance.

=Myopia=

Myopia means nearsightedness. This defect is undoubtedly hereditary to
a certain degree, but it is doubtful if, other conditions being
favorable, any man would give up a girl because she is myopic or vice
versa. Still, if the condition is extreme, as it sometimes is, it
should be taken into consideration. And where both the man and the
woman are strongly myopic some hesitation should be felt in
contracting a marriage. If the husband alone is myopic, then the
defect may be transmitted to the sons but not to the daughters, and
these daughters may in their turn transmit the defect to their sons
but not to their daughters. In other words, the defect is more or less
_sex-limited_.

=Astigmatism=

This is a defect of the eye, depending upon some irregularity of the
cornea or the lens, in which light rays in different meridians are not
brought to the same focus. It is to a certain extent hereditary, but
plays an insignificant role. It is an undesirable trait, but cannot be
considered a dysgenic factor.

=Baldness=

Premature baldness is a decidedly inheritable trait. And so is
premature grayness of the hair. But it is doubtful if any woman would
permit these factors to play any role in her choice of a husband.

=Criminality=

Almost a complete change has taken place in our ideas of criminality,
and there are but very few criminologists now who believe in the
Lombrosian nonsense of most criminality being inherited and being
accompanied by physical stigmata of degeneration. The idea that the
criminal is born and not made is now held only by an insignificant
number of thinkers. We know now that by far the greatest percentage
of crime is the result of environment, of poverty, with all that that
word implies, of bad bringing up, of bad companions. We know that the
child of the criminal, properly brought up, will develop into a model
citizen, and vice versa, the child of the saint, brought into the
slums, might develop into a criminal.

Then we must remember that there ar
