Fenwick^ found the frequency of occurrence to be per cent. Ebsteins^ figures, based on 600 autopsies, are higher, per cent. The cause of the condition is not definitely known, but the growthsseem in some way connected with chronic gastritis. It is more frequentin males, and is rare before the age of forty.
