a mucilaginous liquor secreted by certain glands, and serving to lubricate many of the internal cavities of the body. In its natural state it is generally limpid and colourless; but, from certain causes, assumes a thick consistence and a whitish colour like pus. For the distinguishing characters between pus and mucus, see Chemistry, No 2769.

MUCK, or RUNNING A MUCK, is a practice that has prevailed time immemorial in Batavia. To run a muck, in the original sense of the word, is to get intoxicated with opium, and then rush into the street with a drawn weapon, and kill any one that comes in the way, till the party is himself either killed or taken prisoner. If the officer take one of these amocks or mohawks (as they have been called by an easy corruption) alive, he has a considerable reward; and the unhappy wretch is always broken alive on the wheel: but such is the fury of their desperation, that three out of four are necessarily destroyed in attempting to secure them.
