Seeking confidential information about the American Public Health Association in an autograph letter, signed and marked "confidential" 9 November 1872, on Smithsonian Institution letterhead, to Dr. Edward Jarvis of Dorchester, Massachusetts.

8vo. 2-pages, approximately 150 words; docketed by Jarvis at the head of the first page. In part: "While anxious to cooperate with every proper effort to advance the cause of knowledge, I must be careful … there are quite a number of names [in the association] of trustworthy men … others are not of a character fitted to advance properly te objects of the association." Henry is particularly remembered for advances that led to the founding of the U.S. Weather Bureau. Jarvis (1803-1884) was one of the leading 19th-century advocates for care of the insane (see DAB). Folded, but very good. Item #46825
