INCUBUS, n. One of a race of highly improper demons who, though probably not wholly extinct, may be said to have seen their best nights. For a complete account of _incubi_ and _succubi_, including _incubae_ and _succubae_, see the _Liber Demonorum_ of Protassus (Paris, 1328), which contains much curious information that would be out of place in a dictionary intended as a text-book for the public schools.
