[Fr. ambre gris, gray amber.] A substance found floating in the sea or thrown upon the coasts in warm climates, and also in the intestines of the sperm whale, which is believed to be in all cases its true origin. The floating masses are sometimes from 60 to 250 lbs. in weight. In color it is gray, yellow, white, or black, and often variegated like marble. It is much used in perfumery, and to improve the flavor of wines and cordials. In Asia and Africa it is used as a medicine, also as a condiment in cooking.
