r the roots of real crime and to
develop it. Want will weaken the love and mutual respect among the
members of that family, but it will not be strong enough alone to arm
the hands of the man for a matricidal deed, unless he should get into a
pathological mental condition, which is very exceptional and rare. But
the conclusions of the positive school are confirmed in this case as in
any other. In order that crime may develop, it is necessary that
anthropological, social and telluric factors should act together.

We generally forget the conditions of the physical environment in which
we live, because supernatural prejudice tells us that the body is a
beast which we must forget in order to elevate ourselves into a
spiritual life. Manzoni could designate the Middle Ages by the term
"dirty." because they neglected the demands of elementary hygiene, and
thus of human morality. For where the requirements of our physical body
are neglected or offended, there no flower can bloom. The telluric
environment has a great influence on our physical activity, by way of
our nervous system. We feel differently disposed, according to whether a
south or a north wind blows. When Garibaldi was on the Pampas, he
observed that his companions were irascible and prone to violent
quarrels, when the Pampero blew, and that their behavior changed, when
this wind ceased. The great founders of criminal statistics, Quetelet
and Guerry, observed that the change of seasons carried with it a change
in criminality. Sexual crimes are less frequent in winter than in spring
and summer. And with reference to this point I have maintained, and
still maintain, that it is due to the combined effects of temperature
and social conditions, if crimes against property increase in winter.
For lack of employment, the want of food and shelter, intensify the
misery and lead to attacks on property. On the other hand, the cold by
itself reduces sexual crimes and personal assaults. And those who claim
that the longer intercourse between people in summer time has also a
social influence, are also partly in the right.

The most eloquent fact in this respect was mentioned by Murro, when he
pointed out that this change in the frequency of bloody crimes, greater
in the warm months than in winter, applied also to prisoners. Statistics
show that breach of discipline is most frequent in hot seasons. The
social factor does not enter there, because the social life is there the
same in
