OBSERVATIONAL DATA 



Table 5. — Nature of hair 



Among the not old American members, it is seen, there is a very perceptibly larger number 

 of wavy to curly hair. The causes doubtless are racial. 



Grayness, loss of hair. — Nearly all the members of the Academy showed some gray hair, 

 ranging from a few hairs to all or nearly all; and a large percentage showed also more or less of 

 loss, ranging from slight to almost complete. Accurate data in these respects, under the ordinary 

 methods of examination and gaging, are impossible; but a study of the records, such as they are, 

 showed no significant difference in these respects between the two groups of the members of the 

 Academy, nor between the old American group within the Academy and the old Americans 

 at large studied previously. 12 



Moustache, beard, hair oj the body. — A proper study of the moustache and especially that 

 of the beard was impossible, for more than one-half of the members of the Academy wore no 

 moustache and but a few wore a full beard. It is well known that both in color and character 

 the moustache and the beard differ in most cases appreciably from the hair of the head, the 

 moustache tending toward a lighter and more sandy, grizzly, or reddish tinge, while the beard 

 is frequently darker and tending to wavy or even slightly curly. Nothing exceptional was seen 

 or learned in any of these respects in the members of the Academy. Also there was no information 

 about or suggestion of any subnormal or excessive hairiness of the body. 



Color or the Eyes 



The facts that a cursory examination of the eye color is not reliable, that a more intensive 

 and regidated scrutiny in good light is necessary, and that on such close examination many eyes 

 that offhand appeared pure are really found to be "mixed," together with the rational classification 

 of eye-colors, were discussed and shown in the report on the old Americans at large (pp. 35-47). 



The subject received due attention with both subdivisions of the members of the Academy 

 and the general results of this are seen in the next table: 



Table 6. — Color of the iris, condensed results 



The above conditions are remarkably harmonious, particularly as to the pure lights, in 

 all the three groups. In approximately three-fifths of the individuals in each series the iris 

 showed plain signs of admixture of brown-eyed with light-eyed ancestors. There is some pre- 

 dominance of the browns in the old Americans at large. This may be due to the presence in 

 this series of a larger proportion of southerners. Within the Academy the not old Americans 

 show a moderately larger proportion of the brown-eyed, as could have been expected from the 

 racial composition of this group.
