he cause of the
variation. The difference between Catholic and Protestant is, roughly
speaking, the difference between the brachycephalic brunette Alpine
race and the dolichocephalic blonde Baltic race. So that a mixed
marriage in Germany would almost always mean the crossing of two
distinct types.

The investigations of M. Gache in Buenos Ayres covering the period
from 1884 to 1894 inclusive, show that cross breeding has had the
effect of _raising_ the masculinity. The births resulting from unions
of Italian, Spanish and French male immigrants with native-born
Argentine females, show a higher masculinity than the births produced
either by pure Argentine alliances or by pure alliances of any of
these nationalities of Buenos Ayres. Further, the unions of Argentine
males with females of foreign nationality provide a higher masculinity
than is common among Argentines themselves.[34] These facts do not
necessarily contradict the theory that any crossing of great racial
groups diminishes masculinity, for all of the nationalities involved
in this study are predominantly Mediterranean in blood. The theory is
borne out by the statistics of the negroes in the United States, a
large proportion of whom are of mixed blood. For taking as a basis the
number of children of negro descent born during the year ending June
1, 1900 reported by the Twelfth Census, the females predominated,
giving a negative masculinity of 99.8. Furthermore, the percentage of
consanguineous marriage is probably high in the colored population.

114-116.]
The following table compiled from Mulhall[35] and other sources fails
to show any correspondence between the percentage of first cousin
marriage and the masculinity:
