Coon said about Bosniaks:
Bosnia consists of the six provinces, Biha6, Banjaluka, Tuzla, Travnik,
Sarajevo, and Mostar, which lie between western Croatia, Dalmatia,
Montenegro, and the Slavonian plain. The southernmost province, Mostar,
includes the territory known as Herzegovina, which lies nearest to Monte-
negro. The Bosnians serve racially as an approach to the nucleus of Dinaric
giantism in Montenegro. Tuzla, in the northeast, has a mean stature of
171 cm.; Bihac and Banjaluca, in the northwest, of 172 cm.; in Travnik
and parts of Mostar it rises to 173 cm., in Sarajevo to 174 cm., and in
Herzegovina to 175-176 cm., approaching the Montenegrin level. The
mean cephalic index of the Bosnians is over 85; this varies by religions,
with the Catholics the most brachycephalic (86), and the Moslems the
least (84). The Catholics are likewise the tallest and the lightest skinned;
being the oldest population in the region in point of conversion, and the
least affected by outside influences, the Catholic element preserves both
a pre-Slavic and a pre-Turkish racial configuration more completely
than do the partisans of Orthodoxy or Islam.
In hair and eye color the Bosnians are intermediate between Groatians
and Serbs; they are darkest in the northeast, and fairest in the regions near-
est Montenegro. Since they form but an extension of the Montenegrin nu-
cleus, it will suffice here to point out their near identity with the inhabitants
of that former kingdom, and to leave a detailed description for the latter.
