Colijmbium, a metal extracted from the mineral columbite, found in Connecticut. It was first discovered by Mr. Hatchett in 1801, and afterward by a Swedish chemist, who gave it the name of tantalum, having extracted the substance from tantalite. It was proved, however, by Dr. Wollaston, that this metal was identical with columbium, as is also the metal called by Rose niobium. It is of a yellowish white or gray color, and when burnished has a metallic lustre. The name columbium was probably given from its being originally discovered in North America.

Colimbo, Or Calumba

Colimbo, Or Calumba, the root of cocculus palmatus or jateorrhiza palmata, and of J. cahunba, climbing plants of the order meni-spermacece, growing in Mozambique. The root is cut into transverse slices, which are from an eighth of an inch to near an inch in thickness, from one to two inches in diameter, and when of good quality of a tolerably bright yellow color in the cortical portion, somewhat lighter in the interior, and covered with a brownish wrinkled epidermis externally. Columbo contains a crystallizable neutral bitter principle, called colombine, and an alkaloid, berberina. Its medical virtues are those of a pure bitter, slightly if at all stimulating, and generally acceptable to the stomach. American columbo, the root of Frasera Walteri, of the order gentianaceae, and a false columbo from cosci-nium fenestration, belonging to the same order with the genuine, have been sold in Europe instead of the genuine.
