In an article published in 1907 I showed[1] that it rather represents a late stage in the history of the more ordinary forms of the classificatory system. My conclusion at that time was based on the scanty evidence derived from the relatively few Oceanic systems which had then been recorded, but my work since that article was written has shown the absolute correctness of my earlier opinion, which I can now support by a far larger body of evidence than was available in 1907. It remains possible, however, that the Hawaiian system may have had its source in promiscuity, even though this condition be late rather than primitive, but it would be going beyond the scope of these lectures to deal fully with this subject here.
