BERRY-BEARING HEATH:** A genus of the triandra order, belonging to the monoeica class of plants. In the natural method this genus is ranked by Linnaeus under the 54th order, *Myxellaceae*; and likewise among those of which the order is doubtful. The male calyx is triplicate; the corolla tripetalous; the stamens long; the female calyx is triplicate; the corolla tripetalous; the styles nine; the berry nine-seeded. There are two species; one of which, viz. the nigrom, which bears the crow-cake berries, is a native of Britain. It grows wild on boggy heaths and mountains. Children sometimes eat the berries; but, when taken in too great quantity, they are apt to occasion a headache. Grouse feed upon them. When boiled with alum, they afford a dark purple dye. Goats are not fond of it. Cows, sheep, and horses refuse it.

**EMPHASIS,** in rhetoric, a particular stress of the voice and action, laid on such parts or words of the oration as the orator wants to inforce upon his audience. See Declamation; Oratory, Part IV.; and Reading.

**EMPHYSEMA,** in surgery, a windy tumor, generally occasioned by a fracture of the ribs, and formed by the air inflating itself, by a small wound, between the skin and muscles, into the substance of the cellular or adipose membrane, spreading itself afterwards up to the neck, head, belly, and other parts, much after the manner in which butchers blow up their veal.
