While a great deal of scattered evidence about many animals consecrated to Greek gods points in this direction, it will be enough, for the present, to examine the case of the Sacred Mice. Among races which are still in the totemistic stage, which still claim descent from animals and from other objects, a peculiar marriage law generally exists, or can be shown to have existed. No man may marry a woman who is descended from the same ancestral animal, and who bears the same totem-name, and carries the same badge or family crest, as himself. A man descended from the Crane, and whose family name is Crane, cannot marry a woman whose family name is Crane. He must marry a woman of the Wolf, or Turtle, or Swan, or other name, and her children keep her family title, not his. Thus, if a Crane man marries a Swan woman, the children are Swans, and none of them may marry a Swan; they must marry Turtles, Wolves, or what not, and _their_ children, again, are Turtles, or Wolves. Thus there is necessarily an eternal come and go of all the animal names known in a district. As civilisation advances these rules grow obsolete. People take their names from the father, as among ourselves. Finally the dwellers in a given district, having become united into a local tribe, are apt to drop the various animal titles and to adopt, as the name of the whole tribe, the name of the chief, or of the predominating family. Let us imagine a district of some twenty miles in which there are Crane, Wolf, Turtle, and Swan families. Long residence together, and common interests, have welded them into a local tribe. The chief is of the Wolf family, and the tribe, sinking family differences and family names, calls itself 'the Wolves.' Such tribes were probably, in the beginning, the inhabitants of the various Egyptian towns which severally worshipped the wolf, or the sheep, or the crocodile, and abstained religiously (except on certain sacrificial occasions) from the flesh of the animal that gave them its name. {107} * * * * *
