their own dead: they must have devoured then the corpses of those who had to die. Old people died, convinced that by their death they were rendering a last service to the tribe. This is why cannibalism is represented by some savages as of divine origin, as something that has been ordered by a messenger from the sky. But later on it lost its character of necessity, and survived as a superstition. Enemies had to be eaten in order to inherit their courage; and, at a still later epoch, the enemy's eye or heart was eaten for the same purpose; while among other tribes, already having a numerous priesthood and a developed mythology, evil gods, thirsty for human blood, were invented, and human sacrifices required by the priests to appease the gods. In this religious phase of its existence, cannibalism attained its most revolting characters. Mexico is a well-known example; and in Fiji, where the king could eat any one of his subjects, we also find a mighty cast of priests, a complicated theology,(38) and a full development of autocracy. Originated by necessity, cannibalism became, at a later period, a religious institution, and in this form it survived long after it had disappeared from among tribes which certainly practised it in former times, but did not attain the theocratical stage of evolution. The same remark must be made as regards infanticide and the abandonment of parents. In some cases they also have been maintained as a survival of olden times, as a religiously-kept tradition of the past.
