ADUST, ADUSTUS, among physicians, &c. is ap-

plied to such humours as by long heat become of a hot
and fiery nature. Such is choler supposed to be. Me-
lancholy is usually considered as black and adust bile.
Blood is said to be adust, when, by reason of some ex-
traordinary heat, its more subtle parts are all evaporat-
ed, leaving the grosser, with all the impurities therein,
half torrid.
