Smithsonian Institution, Dec. 8, 1869.
Dr. Geo: A. Otis;
Army Medical Museum
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.
