Reading edition
Quoted by Mr. Sedgwick in ‘Med.-Chirurg. Review,’ April, 1861, p. 485. Dr. H. Dobell in ‘Med.-Chirurg. Transactions,’ vol. xlvi., gives an analogous case in which, in a large family, fingers with thickened joints were transmitted to several members during five generations; but when the blemish once disappeared it never reappeared.
