8.Some Australian tribes are divided into four exogamic groups. The laws of exogamy demand that a member of the first group must marry a member of the second group, and a member of the third group one of the fourth group.Cunowexplains these customs by showing that when custom provides that a man in a tribe that is divided into two exogamic units, and in which only members of the same generation are allowed to intermarry, conditions like those found in Australia will naturally develop, if each group has a name, and one set of names are used for the first, third, fifth, generations, and another set of names for the second, fourth, sixth, generations, etc. If we should designate the two tribal divisions by the letters A and B, the generations by 1 and 2, the names of the four divisions would be A1, A2, B1, B2; and in marriages in which is placed first the sex that determines the group to which the offspring belongs, we find that—A1mustmarryB1,andhischildrenareA2B1""A1,""""B2A2""B2,""""A1B2""A2,""""B1
