Mary's Ghost. A Pathetic Ballad.
Body-snatching context
Illegal trade of corpses for medical dissection was common in early 19th-century Britain. Medical schools desperately needed cadavers for anatomical study.
Anatomical commodification
Each body part is treated like a commercial good, distributed to different medical professionals—a pointed critique of medical ethics.
Medical geography
Real London medical institutions mentioned—Guy's Hospital and Dr. Vyse were actual contemporary surgeons and hospitals.
Gallows humor
The ghost's matter-of-fact tone about bodily dismemberment creates a darkly comic effect, typical of Hood's satirical style.
