has proved that the head of the male infant
exceeds that of the female by 3/8ths of an inch
in circumference, and by 1/8th in transverse
diameter. Quetelet has shewn that woman is

believes, male infants often suffer in health for
some years after birth. Owing to this excess in
the death-rate of male children, both at birth

considerably over the males. (53. With the
savage Guaranys of Paraguay, according to the
accurate Azara ('Voyages dans l'Amerique merid.'
tom. ii. 1809, pp. 60, 179), the women are to
