and later by events, took place on the western and northern out- 
skirts of Bohemia, with some penetration into the interior. This 
accounts for the present German population of the Republic, and 
for some recent German admixture. 
In Moravia the knowledge of the earlier Slav tribes is more ob- 
scure; but there are several large old groups whose territorial dis- 
tribution, with dialectic and other differences, have been better pre- 
served to date than those of the tribes in Bohemia. 
The southeastern part of Moravia and the subcarpathian territory 
toward the east, is occupied by the Slovaks. External influences which 
this tribe has suffered in the course of its existence have produced a 
certain amount of dialectic and cultural differences; nevertheless 
everything shows their common origin with the rest of the Slav tribes 
of the Czechoslovak territories. 
CONCLUSION. 
From the data here briefly given it is seen that the roots of the 
present Czechoslovak people are multiple, as in the case of prac- 
tically all other now existing branches of the white race, and that 
some of them reach into hazy antiquity. Besides a little of the 
ancient blood, there is a Keltic and to some extent also a Germanic or 
Nordic infusion. 
Mixtures of this nature, where the racial differences are not ex- 
treme, represent as a rule favorable biological as well as cultural 
conditions, and this with the intense struggle for existence imposed 
upon them by their geographical location, accounts doubtless for 
the historical prowess and acknowledged capabilities of the Czecho- 
slovak people. 
A few notes may be added concerning the physical characteristics 
of the present Czechoslovaks: 
The general average stature of the adult males is 169 centimeters, 
of adult females 157 centimeters. The head is of good size and 
generally brachycephalic. The latter feature, as we have seen, is 
of historic development without any recent heterogeneous immigra- 
tion. The brains, even in proportion to stature, show very favor- 
able proportions. In pigmentation (color of eyes and hair) the 
people range from blonds to brunettes with preponderance of the 
latter. On the whole, physically as well as mentally, they represent 
a sound stock and one of favorable appearance.
