I had to do some fact checking on the doctors' biography as well as on the history of the Yale Medical Institute. My audience, I expected, would be readers somewhat familiar with noted names in the field, so I also verified the credentials of the correspondents and mentors Dr. Ewing and Dr. de Belleville I mention in the post. The image I chose was from a letter, folded in the custom of the times to serve as its own envelope, with the name of the recipient Isaac Coleman, 'student of medicine' in New Haven, CT.
