Xavier BICHAT (1771-1802). L.A.S., to citoyen Rousille-Chamesern, physician in Paris; 1page in-4, addressed. Very rare letter from this great physician who died at the age of 31. He recommends a young soldier who wishes to be discharged; "the obliging interest you have shown me has emboldened me". Bichat then adds: "He is the brother of a man to whom the doctors of the Hotel-Dieu have great obligations; for he is busy from morning to night covering up their nonsense. He is the brother of the gravedigger of Clamart".
