n of things may be explained bysupposing that the cysts were formed in or upon the naevus, as they are produced else-where ; and that subsequently, by pressure upon the walls of the vascular sacs, theywere made to communicate with these, or with the supplying venous trunks; or, thatthe current of blood was cut off from the venous sacs, and the blood itself absorbed,and its place occupied by serous fluid.

tures. The nature and tendency are simple; yet degeneration is pos-sible, while discussion is impossible; and therefore early extirpation isexpedient. 6. The Calcareous Tumour, also comparatively rare, is most fre-quently found.in the face and neck—especially in the former situation,in the vicinity of the parotid gland. In most cases, the stroma of theearthy deposit would seem to be the hypertrophied texture of a lym-phatic gland. The tumour is superficial, loose, painless, hard, of slowgrowth and small size; its surface is generally unequal. It has notendency to degenerate ; being in fact but a mass of unorganized mat-ter. Absorption, however, is hopeless; and removal may become expe-dient, on account of the inconveniences attending its position. Fromthe circumscribed form, small size, and slightness of adhesion, the dis-section is easy; little more than simple incision is required. Calcareous formations are found in the ovary, in the testicle, in thelung, and wherever in the body
