The longest middle fingers measure 2 inches (Nos. 8 and 28). The 

 shortest measures 1^ inches (No. 21), and three measure li inches 

 (adults). 



The tallest male i-s 04.i inches in height (No. 28); the tallest 

 woman is 59 inches (No. 26) ; the shortest woman 52 inches (No. 9). 



B. Feet. 



The shortness of the feet is "due solely to the abortivf middle 

 phalanx, and the somewhat stunted growth of the first." 



"The so-called first phalanx of the big-toe is considerably shortened"; 

 in most cases it is reduced to a cube, and in some the shortening goes 

 even further. 



" The middle phalanx in the other toes has become ankyloscd to 

 the terminal one in every adult." This ankylosis " occurs at an earlier 

 age in the foot than in the hand, though the hand as a whole is more 

 abnormal." 



"There is an absence of the basal epiphysis of the first, jjhalanv 

 of the big-toe, though it is conspicuous in the first phalanx of each of 

 the other toes (in children), so that this bone appears to be really 

 homologous with the second phalanx of the other toes." 



Metatarsus. There is very little wrong with the metatarsal bones, 

 in which respect they differ from the metacarpals. In two cases (PI. XIV, 

 Nos. 27 and 28) the third and fourth are the shortest of the series. 



Thigh and Leg. These are shorter than normal, but the numbers 

 especially of the normals are toi> few from which to calculate a reliable 

 average. There is no doubt, howi;ver, that the short 



Stature is entirely accounted for by the shortness of the luwi'r limbs. 

 When the adults are seen seated they do not strike one as being 

 particularly short people, but on standing up it is at once apparent 

 that they are considerably below the average height. The spinal column 

 is therefore approximately of the normal length. 



This fact seems fairly clear fi-om the j)hotographs of the t\\ o brothers 

 (PI. XI): the one on the right (No. 37) is 17^ years old, 59^ inches in 

 height, and is Braehydactylous ; the other one is 14 years old, 3 inches 

 taller, and is not Braehydactylous. The difference in the length of the 

 legs is very obvious, which no doubt accounts for their difi'erence in 

 stature. 



The infant (No. 48) is three-quarters of an inch taller than his 

 normal twin sister, in this respect presenting a striking and unexpected
