The Pirrauru of the Dieyerie is absolutely identical with the Punalua of the Hawaiians; and these institutions were not described by travelers who rushed through the territories of those tribes without knowing their language, but by men who lived among them for decades and fully mastered their dialects.... I have shown how far the class system corresponds to the Hawaiian system. It is and remains a fact, that it contains a long series of terms that cannot be explained by the relations in the so-called consanguine family, and the use of which creates confusion, if applied to this family. But that simply shows that Morgan was mistaken about the age and present structure of the Hawaiian system. It does not prove that it could not have grown on the basis assumed by him.... If the opponents of Morgan dispute that the so-called consanguine family is based on blood kinship, they are right, unless we wish to assign an exceptional position to the Australian strata of generations. But if they go further and declare that the subsequent restrictions of inbreeding and the gentile order have arisen independently of relationships, they commit a far greater mistake than Morgan.
