several million individuals — and it reappears in the child, the mere doctrine of chances almost compels us to attribute its reappearance to inheritance. Every one must have heard of cases of albinism, prickly skin, hairy bodies, &c., appearing in several members of the same family. If strange and rare deviations of structure are

would be, to look at the inheritance of every character whatever as the rule, and non-inheritance as the anomaly.
The laws governing inheritance are quite unknown; no one can say why
