Dear Sir:
I beg to inform you that the tumor of mediastinum in the case of J. Chase, colored, contributed by you Dr D.S. Lamb [name noted in pencil] to this Museum on March 28, has been examined under the microscope and proves to be a gumma.
Very respectfully,
Walter Reed
Surgeon, U.S. Army,
Curator.
