The credit of having been the first fully to recognise the social importance of these differences belongs to J. Kohler. In his book "Zur Urgeschichte der Ehe," which I have already mentioned, he studied minutely the details of many different systems, and showed that they could be explained by certain forms of marriage practised by those who use the terms. I propose now to deal with classificatory terminology from this point of view.
