Smithsonian Institution, Dec. 8, 1869.
Dr. Geo: A. Otis;
Army Medical Museum
Dear Sir:
A gentleman in New York has offered us a Series of valuable Indian relics provided we can obtain for him a collection of the “Photographs of injuries to bones, and other surgical illustrations,” prepared under the direction of the Army “Medical Museum.” If you can furnish us with such a collection you will place us under an obligation which we shall be happy to reciprocate, as the series of relics offered contains many objects that we earnestly desire to posses.
Your obdt. Servant
Joseph Henry
