Warren, ether was administered to a man in the Massachusetts General Hospital, from whose groin a vascular tumor was removed while the patient was unconscious. Dr. Morton obtained a patent for his discovery in November, 1846, under the name of Letheon, offering, however, free rights to all charitable institutions; but the government appropriated his discovery to its use without compensation.

He died in New York City, Jan. 24, 1848. A bronze statue of Dr. Wells has since been erected in Bushnell Park, Hartford, bearing an inscription crediting him with the discovery of anesthesia, although his claims and those of Drs. Charles T. Jackson, John C. Warren, William T. G. Morton, and Gardiner Q. Colton, formed the cause of a notable controversy.
