WOOLLY-HALRED MEN. 307 
hair and speech, because they are much more strictly 
hereditary than the form of the skull. 
Comparative philology seems especially to be becoming 
an authority in this matter. In the latest great work 
on the races of men, which Friederich Miller has pub- 
lished in his excellent “ Ethnography,’ he justly places 
language in the fore-ground. Next to it the nature of 
the hair of the head is of great importance ; for although it 
is in itself of course only a subordinate morphological 
character, yet it seems to be strictly transmitted within 
the race. Of the twelve species of men distinguished on 
the following table (p. 308), the four lower species are 
characterised by the woolly nature of the hair of their 
heads; every hair is flattened like a tape, and thus its 
section is oval. These four species of woolly-haired men 
(Ulotrichi) we may reduce into two groups—tuft-haired 
and fleecy-haired. The hair on the head of tuft-haired 
men (Lophocomi), Papuans and Hottentots, grows in 
unequally divided small tufts. The woolly hair of fleecy- 
havred men (Eriocomi), on the other hand, in Caffres and 
Negroes, grows equally all over the skin of the head. All 
Ulotrichi, or woolly-haired men, have slanting teeth and long 
heads, and the colour of their skin, hair, and eyes is always 
very dark. All are inhabitants of the Southern Hemi- 
sphere; it is only in Africa that they come north of the 
equator. They are on the whole at a much lower stage of 
development, and more like apes, than most of the 
Lissotrichi, or straight-haired men. The Ulotrichi are 
incapable of a true inner culture and of a higher mental 
development, even under the favourable conditions of 
adaptation now offered to them in the United States of
