Teeth. 



In addition to the examination of the body, limbs and other pre- 

 viously mentioned parts, attention was given also to the condition 

 of the teeth of the children. Among this class of individuals the 

 condition of the teeth was found to be fine* that is there were no 

 more decayed and absent teeth in the mouth than up to two, in 54, 

 or 53 per cent, of the cases. The teeth were good, that is, there were 

 between two and six lost and decayed, in 36 per cent, of the cases. 

 The teeth were mediocre, that is, there were lost and decayed more 

 than six but less than a half of the total number, in a little over 

 9 per cent, of the cases; and of bad teeth, or those where a half or 

 more of the total number were lost and decayed, there were three 

 cases, or about 3 per cent, of the total. 



Careful inquiries were made with the teachers and attendants of 

 the children as to their abilities in learning and as to their char- 

 acters since they have been under observation. From the data thus 

 collected it appears that there were among these children 87, or 83 

 per cent., with abilities that could be said to be about the average 

 for children of the same ages outside the institution. In 3 per cent, 

 of the cases the abilities of the children were decidedly superior; and 

 in 14 per cent, the abilities were in some way inferior to the general 

 average. Almost half of the children with inferior abilities in learn- 

 ing had some known bad heredity. 



* The denominations used here are entirely arbitrary, but I have used them extensively in 

 examining different classes of people and find them very satisfactory.
