surname of Sedigitus in consequence. He also states, that

Persons who had the surname of Flaccus were so called 
from their pendulous ears, and numerous other instances are 
recorded by classic writers of surnames being derived from 
family marks. 
Anatomical researches have not been so generally extended 
as to determine the prevalence of internal peculiarities, and 
perhaps they do not reach to the sanguineous system. I have 
known two instances, in two different families, of the high

a man, and who is now living, who has a small pendulous 
fold attached to the skin of his upper eyelid, and the same 
peculiarity has been transmitted to his four children. It would 
have been interesting to know, whether any similarity of 
structure existed in the families of the two rare examples of 
a total transposition of the abdominal and thoracic viscera.
