 nose in the more cultured and aged old Americans at large; and that while evidently affected 

 somewhat by senile changes, these changes have been but very moderate during the ages rep- 

 resented by the members examined. 



The Mouth 



The mouth yields itself to the measurement of its width, which differs racially, in the two 

 sexes, and by age. The dimension is measured with the lips in easy apposition, between the two 

 points in the corners of the mouth where the mucous membrane joins the skin. 



In the older members of the Academy this measurement has doubtless suffered some loss 

 through the absorption of the alveolar processes, on the state of which the mouth width depends 

 to a material degree. In a few individuals the disturbance has been such as to necessitate 

 elimination of the measurement. The results in the rest will be seen beneath:
