IN MAN

HE following account of the in- 
heritance of limited syndactyly 
through three generations is re- 
ported for the purpose of placing the 
case on record. Syndactyly, or webbed 
digits, is recognized as a dominant 
Mendelian trait in man and a number 
of instances of its inheritance have been 
reported before. There appears, how- 
ever, much variation in the number of 
digits affected and in the extent of the 
web along the digits, in view of which 
full recording of such pedigrees is 
worth while. 
In this family the web occurs only 
on the feet and only between the second 
and third toes. In each case it is 
present on both feet. The character of 
the web is indicated by the accompany- 
ing X-ray photograph, Figure 23. The 
skeleton is entirely normal, but the 
second and third digits are united be-
