The writer reported an interesting case of leper. In that case 6 of 7 brothers who came from the parents by a marriage of cousins, suffered from leper. The souce of the disease seemed to be the paternal uncle who had lived with the family. 3 of them were deaf and dumb inherently and 4 had a remaining mem- brane in the pupils. According to previous papers 2 brothers or more, who suffered from leper, were infected almost always from the mother.
The infection of leper seemed to have nothing to do with the consanguineous marriage. The congenital deaf and dumbness in this case owed to the consan- guineous marriage of the parents, remaining membranes of the pupils, however, seemed not due to the latter.
