Cuneiforme

Os, (from cuneus, a wedge,) clavi-cula, cavilla, Chalcoideum os, Basilare os. A name of the os sphenoides, from its being wedged between the other bones. Also the third bone of the first row in the wrist; called so from its appearing like a wedge sticking between the two rows. See Carpus.

Cuneiforme os externum, or chalcoideum externum of the tarsus. At its posterior edge it joins the os naviculare and os cuboides; it supports the metatarsal bone of the toe next the little one, and that next the great one and of the middle toe. The os cuneiforme medium vel minimum, is still more wedge-like than the former; it sustains the metatarsal bone of the toe next to the great one. The os cuneiforme internum vel maximum sustains the os metatarsi of the great one. All these are cartilaginous at the birth of children. These bones are also called chalcoidea ossicula.

These are vessels used for separating baser metals from gold or silver; they are made of earth, and are hollowed like flat cups, from which they have been named: they resist every degree of fire that is needful to keep any metal in fusion, and retain these metals when fused; but the calces of some metals, particularly of lead, penetrate the common cupels. The ashes of bones or of plants that have been calcined are therefore employed, though Cramer prefers those made with plaster: and later chemists prepare them of gold or platina. The bone ashes must be perfectly calcined, then levigated; after which they must be formed into a paste, moulded into their proper form, and burnt in a potter's furnace. See various directions concerning them in the Dictionary of Chemistry.
