Anthropological Investigations. 



acters, however, become better differenciated and more pronounced 

 with the age of their bearers. 



I append here a table which gives the percentages of congenital 

 and other classes of the abnormalities of the children according to 

 their ages. The table suffers very much by the small numbers ;f 

 individuals represented in some of the divisions ; but it shows fairly 

 well the gradual diminution with age of the bulk of congenital de- 

 fects; the increase with age of the habit abnormalities; and the ex- 

 cess of the congenital defects in the male over the female. The pro- 

 portions of abnormalities which I included under " origin question- 

 able " increases much with the ages of the children; this increase 

 signifies that some of the characters whose origin I class as question- 

 able are really acquired. There were included in this class of abnor- 

 malities, principally, the very prominent occiput; the deflections of 

 the nose; the polygonal gums; most of the abnormalities of the 

 dentition and of the teeth; the high and the gothic palate, and the 

 deflected uvula. 



Percentages of abnormalities according to their origin at different ages 

 of the white and colored children, male and female.

Measures. 



The results of the measuring when tabulated according to the 

 ages of the children proved to be of great interest, and the facts 

 that some of these tabulations clearly show are new. Some 

 disturbance in the figures was occasioned throughout by the small 

 numbers of subjects in some of the divisions, but these irregularities
