War Department,
Surgeon General’s Office,
Washington, May 17th 1869
Dear Doctor,
The Surgeon General “approves” of your sending anything you can spare and deem best to convey to Russia.
It is desirable to foster the ‘fraternal’ relations which now exist between the “subjects of the Czar” + ourselves.
Very truly yours,
C.H. Crane
Dr. Otis
U.S.A.
