Correspondence Dated April 17, 1848, from Charles T. Jackson, MD, to John Snow, MD

A previously unpublished four-page letter from Charles T. Jackson, MD, to John Snow, MD, was acquired in December 2016 by the Wood Library-Museum of Anesthesiology, Schaumburg, IL. The letter may be a draft or a copy of the letter which may have been sent to Snow in 1848. Jackson's letter to Snow does not reveal any significant new insight into the controversy over the discovery of etherization. A hitherto unknown meeting of Jackson's former chemistry student, Joseph Peabody, and John Snow, MD, was revealed in the letter.
