uestion; does he not favor conjugal life by only charging
half-price on the boats for women who travel with their husbands!

Other classes have a less obvious influence on sexual life. On the
whole, however, all sexual isolation of castes has an unfavorable
influence. Wherever the prejudices of a caste compel its members to
intermarry, certain special degenerations are produced. Good quality
in man is not derived from class or position, but from true innate or
hereditary nobility of character, and this alone should be the object
of positive selection, without any distinction of classes.

=Individual Life.=--There is no doubt that the mode of life of the
individual exerts an influence on his sexual life. High living
combined with little bodily exercise generally increases the sexual
appetite, while insufficient food combined with severe muscular work
diminishes it.

Intellectual work acts in a variable manner. A distinguished
psychologist assured me that intense intellectual work excited his
sexual appetite; others have said the opposite. As a rule, a sedentary
life increases the sexual appetite; a life full of occupation and
muscular activity diminishes it. But the question is complicated by
other influences.

Alcohol diminishes sexual power, while exalting desire or even
perverting it. The artificial excitants of the sexual appetite,
cultivated by modern civilization by interested speculation, act in
rather a different way. Erotic pictures, obscene novels and dramas,
etc., constitute an unhealthy medium in our centers of civilization,
which overexcites and corrupts the sexual appetite. The more delicate
and poisonous the perfume of this atmosphere and the more aesthetic the
refinement by which it titillates the senses, the greater is its
destructive action.

The question of the reunion or separation of the sexes plays an
important part. Life in common among girls and boys from infancy
usually diminishes sexual excitation, in the same way as among
brothers and sisters. We find something analogous in different
branches of human activity where the two sexes live together; for
instance, at college, in the fields, and in general where work and
play is common to both sexes.

There are, however, certain exceptions to this rule, which must not be
taken too generally. Under certain circumstances, life in common of
the two sexes leads to unfavorable and even perverted sexual
excitation. This is especially the case when a
