Writing
Although Dr. John Warren published a number of pamphlets and articles—including the first article to appear in The New England Journal of Medicine and Surgery—this is his only monograph. It was published near the end of his life and concerns the medical uses of mercury in fever treatment.
Partially in the handwriting of Dr. John Warren, this volume of lecture notes, beginning on December 10, 1783, contains the earliest surviving record of teaching at Harvard Medical School. The lectures were delivered in Harvard Yard, probably in Holden Chapel.
After summarizing the history of his subject, Dr. Warren then justifies dissection as an essential component to anatomical study: "At the first view of dissections, the stomach is apt to turn, but custom wears off such impressions. It is anatomy that directs the knife in the hand of a skilful surgeon, & shews him where he may perform any necessary operation with safety to the patient. It is this which enables the physician to form an accurate knowledge of diseases & open dead bodies with grace, to discover the cause or seat of the disease, & the alteration it may have made in the several parts."
