In-12, 20 p., without cover, as issued. Posthumous editio princeps of this strange letter, uncommon as only 60 copies were printed, which mocks its addressee, evokes genetics, wonders about the resurrection of bodies after death and makes an acid misogynistic comment: "I do not yet know whether ladies will retain their sex in this universal upheaval, or whether only those who have lived well will be granted the form of a man". Copy preserved in a small reused vellum jacket. Trace of rust on a pin (Brunet, II, 1333).
