With the foot as with the hand, the old American group of the Academy is very close to the 

 more cultured old Americans in general, the only difference heing that in the latter the foot is 

 slightly broader and the index consequently higher. The Academy group of European birth or 

 more recent American derivation shows a slightly larger and particularly longer foot, as it showed 

 a slightly larger hand than either of the two groups of the old Americans. In both series of the 

 academicians the foot is smaller and especially narrower than it is hi most of the recent European 

 immigrants to this country, 42 and these differences come out especially clearly when the foot 

 dimensions are compared with stature, as may be seen in table 69. All this relates, I believe, to 

 the more sedentary habits of the academicians and the consequently fewer total stresses their 

 feet had to endure.
