Abru'ption. n.s. [abruptio, Lat.] Breaking off, violent and sudden separation.
Those which are inclosed in stone, marble, or such other solid matter, being difficulty separable from it, because of its adhesion to all sides of them, have commonly some of that matter still adhering to them, or at least marks of its abruption from them, on all their sides. Woodward's Nat. Hist. p. 4.
