It is of course impossible to explain all the ratios in this table.  Much variation is here due to chance, and a few additional cases might appreciably change any of the ratios.  It will be noticed, however, that the two categories whose masculinity is most similar (100 and 101), are derived from cases taken from the same families and from the same environment, and differing only in that the first is closely consanguineous while the second is not.  The third and fourth groups, separated from the first two by at least a generation, and probably living in a different environment, differ greatly in masculinity from them.  In the fourth group are included 1-1/2, second, third, and a few even more distant cousins, all more distantly related than first cousins, and taken from the same genealogies as these; yet the masculinity is much greater.

An analysis of the cases collected fifty years ago by Dr. Bemiss, of course without thought of masculinity, gives the following result:[40]

[Footnote 40:  Bemiss, Report on Influence
of Marriages of Consanguinity, pp. 420-423.]
In the “Marriage of Near Kin,” Mr. Huth
gives a list of cases of consanguineous marriage collected
by various persons from all over Europe.[41] He is
free to say that they are worse than useless for the
purpose for which they were collected, that of determining
whether or not such marriages produce degeneracy,
but in so far as the sex of the children is concerned
they would not be biassed.
