The second phalanx of the thumb differs in the two families : in 

 No. 1 the basal epiphysis was absent but in this family it is present. 



The abnormality in the toes appears to be practically identical in 

 the two families for in both there is an absence of the middle phalanx-

epiphysis and in the adults there is ankylosis of the second and terminal 

 phalanx in the small toes. In each abnormal individual both hands 

 and both feet are symmetrically affected, so that, in this respect, the 

 peculiarity is as extensive as in No. 1 family.
