and broader than the nose of the white child. These differences in- 

 crease somewhat with the age of the children. 



The lips of the colored subjects are very prominent. This is 

 partly due to the greater prognathism of the alveolar processes, but 

 besides this the lips of the colored children are substantially thicker 

 than are those of white children. 



The mouth is broader and it is also more spacious antero-posteri- 

 orly in the negroes. This is due to the fact that in the colored 

 child the palate is more spacious and longer than it is in the white. 



The teeth of the negro children are often stronger than are those 

 of white individuals. Irregularities in the setting of the teeth, which 

 are so frequent in white children, are quite rare among the colored. 

 Dentition in the colored is more regular. 



The uvula is frequently shorter and stouter in the colored 

 than it is in the white children, and is less frequently deflected in 

 the former. 



The lower jaw is often somewhat higher and the lower maxilla a 

 little stronger in the colored subjects than it is in the white. 



The ears of the colored deserve special notice. They show in 

 many cases a marked and almost specific character, which is but 

 rarely seen in the white. This character consists in that the helix is 

 bent on itself and compressed at the highest fourth of the ear. The 

 negro ear is also generally somewhat smaller in all its dimensions 

 than the white one. In a certain proportion of cases the ears of the 

 colored children are broader in the lower half than they are in the 

 upper. 



The body shows marked differences in the two classes of children, 

 and some of these differences are more marked in children of cer- 

 tain ages than they are in adults. These differences are more 

 marked in the female children than in the male. 



In general the body of the negro child shows less adipose tissue 

 and greater muscular development. The average strength in each 

 arm, as measured by the dynamometer is greater, not only at all 

 ages of the colored children, but also when calculated in proportion 

 to every pound of weight of the body. 



The pelvis of the colored child is more inclined forwards than 

 that of the white child, and this is equally true in both sexes.
