relatively cold. This phenomenon is clearly shewn by Tables XIV. and
XV. In Denmark and in Saxony the mortality - during the first month of
life appears to be greatest in summer, or at the beginning of autumn;
at Budapest, besides the summer maximum, there is another not quite so
marked in winter; in Italy, the winter months are by far the most unfavor
able to the newly born, while one can only^just notice the slight increase
in mortality during July and August. Such differences are'^probably due
to several causes : on the one hand, in colder countries the children are
better sheltered from the rigours of the winter than in hotter countries;
on the other hand, a different proportion in the number of the artificially
fed may have a decisive influence (10), as this practice increases infant
mortality especially in hot seasons. (See Table XVI.) (II.)
It is not hard to find a reason for the monthly variation in the numbers
of still-born throughout the year; the number of the still-born depends in fact
on the influence that the climate exercises, not upon the organisation of the
child, but upon that of the mother, and adults cannot be protected from the
inclemency of the weather so easily as the newborn : therefore, for adults the
