Essentially unreadable by a non-specialist (that includes me!), but with the odd fascinating snippet, such as:
A certain order is brought into this multiplicity of types if we search for those combinations of kin types which are never classified together in occurrent types, except in type 1 which involves a single term for all relatives. In fact, there is only one such set consisting of FaFa and MoMo. Among all terminologies which involve a classification, that is all outside of type 1, those for which I have found examples, namely 2, 3, 8, 9, 10, 12, and 15, put FaFa and MoMo in different classes.
