Co*ag`u*la"tion (?), n. [L. coagulatio.]
The change from a liquid to a thickened, curdlike, insoluble state, not by evaporation, but by some kind of chemical reaction; as, the spontaneous coagulation of freshly drawn blood; the coagulation of milk by rennet, or acid, and the coagulation of egg albumin by heat.
