splenium is absolutely and relatively larger in the Negro than in the 
Caucasian, while the genu is relatively and absolutely smaller. The 
isthmus and body are relatively about the same size in the males of the 
two races, but in the females the isthmus is relatively smaller in the 
Negro, while the body is relatively larger. The hooked beak of the genu 
is larger in any case in the Caucasian, especially in the female. 
Composite types of both races and sexes.—There are four of these 
types made up as follows: Type I is a composite of Type II Negro male, 
and Type I of the others, twenty-two individual cases in all, thirteen 
Negro and nine Caucasian. The Caucasian traits predominate. This 
type represents the young, active, vigorous individuals. Type II is a com- 
posite of Types I Negro male, II Negro female and Caucasian female, 
and Type IV Caucasian male, twenty-nine individual cases in all, twenty- 
one Negro and eight Caucasian. The Negro traits predominate. This 
type represents the old and the passionate. Type III is a composite of 
Type II Caucasian male, and Type III Negro male and Type IV Negro 
female, twenty-one individual cases in all, fifteen Negro and seven Cau- 
casian. The Negro and Caucasian traits are well mixed. This is a Mu- 
latto type. Type IV is a composite of the remaining types, twenty-eight 
individual cases in all, fifteen Negro and thirteen Caucasian. This type 
represents the mentally dull, the demented, and the degraded. 
Whenever the number of Caucasian exceeds one-third of the whole 
number of cases in any type the Caucasian traits predominate. This may 
indicate a certain amount of Caucasian mixtures among the Negroes. 
The American Negro may be divided into two groups, each with subdi- 
visions.” The first group comprising the greater number of blacks, being 
represented by the Negro types I, II and ITI, and the second group, includ- 
ing only a comparatively small number, being represented by the Negro 
Type IV. The first group includes the Guinea Coast Negro and may he 
the few Hottentots in America, and is divided into three classes. First 
the Hottentot, or Bosjesman, having gray or old yellow skin resembling 
dirty varnished oak; low, dwarfed stature, either weak, or squat and mus- 
cular ; long, woolly hair, in small obliquely inserted tufts; very dark eyes, 
wide apart; extraordinarily broad, flat nose; large mouth, with thick, 
projecting, turned-out lips; enormous prognathism ; heads extremely doli- 
chocephalic; the smallest brains (900-1000 grams) of any human beings 
probably; and lastly, having the distinctive steatopyga and the tablier 
which are not always present. This class is comparatively rare. Sec- 
ondly, the low class Guinea Coast Negro, the most ancient and most class- 
ical Negro type, having a cool, velvety skin, glossy, and varying from a 
reddish, yellowish, or bluish black to jet black; low stature, well knit and
