(From cera, wax). The wax in the ears. The Latins.call it cerea, aurium sordes, and marmorata aurium, cypstle, cypselis,fugile. It in-viscates, and retains insects, and prevents their hurting the membrana tympani. It is a yellow, oily, bitter, and viscid fluid, which is inspissated by stagnation, softens by heat, and evaporates in a white smoke, whose odour resembles that of burning fat. By a continuance of the heat, it melts, swells, grows dark, and emits an am-moniacal and empyreumatic odour. It mixes with water, forming an emulsion, which, on putrefaction taking place, deposits white flakes. Alcohol dissolves more than half; and, when evaporated, a deep coloured substance remains, nearly resembling the resin of bile. What the alcohol does not dissolve appears to be albumen, which, when burnt, leaves marks of soda and phosphat of lime. -Ether dissolves it, but the solution is less coloured; so that, added to these ingredients, it seems to contain a peculiar colouring principle. It is separated from the glands in the part of the ear in which it is found. It is fluid when first discharged, but soon thickens by stagnation. Wax, under some circumstances, occasions deafness.
