RARE AUTOGAPH LETTER FROM DR. JOHN MORGAN. Written one year before his death, John Morgan thanks the Medical Society of New Haven for their gift to him of "Cases and Observations" [Cases and Observations; by the Medical Society of New-Haven County, in the State of Connecticut. 1784.], and sends a volume of "theses, discourses, dissertations and addresses on the subjects of learning, and the advancement of useful science, especially medical, on the continent of North America."
John Morgan was the founder of the first medical school in Colonial America at the College of Philadelphia (later, the University of Pennsylvania), as well as the American Philosophical Society, and also served as the second Chief Physician and Director General of the Continental Army (the precursor to the Surgeon General). Letters by Morgan are rare.
