8 OBSERVATIONS AND MEASUREMENTS ACADEMY MEMBERS < Mem0 [vol N k xxm, 



The detailed records disclose various additional items of interest and the data appear defi- 

 nite enough for a valid comparison with those secured on the outsiders: 



i Includes 2 (2 percent) slate blue. 



• Includes 1 (2 percent) slate blue. 



! Includes a few slate blue. 



There are, it is seen, but minor differences between the two classes of members of the Acad- 

 emy. There is more of appreciable difference between the academicians and the old Americans 

 at large; however, the latter have shown more light blues, greenish, and light browns. These 

 differences are connected in all probability with age. The pigmentation of the iris is certainly 

 affected by age, and that both during the adult stage proper and during senility. 



The main facts brought out are that the two groups of the members of the Academy show 

 no important differences in eye color; and that, though there are some apparent dissimilarities, 

 both present a close fundamental agreement with the old American population outside of the 

 Academy. 



Of the "mixed" eyes the predominant color was, in the order of frequency, medium grayish 

 blue, gray, medium blue, slate blue, brownish, and greenish. The brown in the blue, gray, or 

 greenish eyes occurred as traces, specks, spots, splotches, and in one case as a marked segment; 

 the bluish or grayish in brown eyes was in splotches, or occurred diffusedly in the outer third of 

 the iris. All this is as in the mixed eyes of the old Americans at large. 



The Forehead 



The subject of the height of the forehead has been dealt with already in a special article I3 

 and thus needs to receive here but a brief consideration. The notes here are limited to the 

 descriptive characteristics of the forehead. These relate to the apparent height of the fore- 

 head and to its slope. 



The apparent height of the forehead does not necessarily mean also a superior height in 

 measurement. It is the visual impression of the region understood under this term in relation 

 to the head and especially the face. The records show the following:
