The Nature of the Investigations, 



The following work is based upon the investigations of one 

 thousand children of the New York Juvenile Asylum and on about 

 one hundred additional cases of children of the New York Colored 

 Orphan Asylum. 



Before proceeding to state the results of my investigations, I 

 think it advisable to make a few remarks about the real nature, 

 principal objects, and mode of execution of the work. 



There were measured and examined, as thoroughly as possible 

 without offense to the modesty of the children, one thousand of the 

 inmates of the institution. In addition, as already mentioned, a 

 number of the most important measurements were secured on 

 about one hundred negro children, inmates of the New York 

 Colored Orphan Asylum. 



In selecting the measurements to be applied to the children I 

 have chosen all those which can be expected to show the principal 

 characteristics of the children's evolution, and I have excluded all 

 those which are either of a secondary importance, or very difficult, 

 or uncertain of execution. The following measures were taken 

 ■on each child: 



I-. Height. 



2. Sitting height. 



3. Arm expanse. 



4. Weight. 



5. Depth of the chest (at the height of the nipples). 



6. Width of the chest (at the same height). 



7. Maximum circumference of the head. 



8. The greatest length of the head. 



9. The greatest width of the head. 



10. The height of the head (from meati line).
