From J. W. Clark   8 September 1877

Dear Sir,

On my return from the Continent last month in turning over some old notes I came across the following singular case of inheritance confined entirely to one sex—¹

June 1875— A friend informs me that his wife’s “large toes are united to the second toes by skin extending as far as the first joint.” This he says has been the case with all the females in her family for a long time— how long is not known. Of her 3 children the two eldest are girls who also possess the same pecularity   the boy however does not, & it appears that no male member of the family were ever known to.

Believe me dear Sir yours most respectfully | J. W. Clark.
