CADMIUM

n.A metal discovered by M. Stromeyer, in 1817, in carbonate of zink, at Hanover. Its color is a fine white, with a shade of bluish gray, resembling that of tin. Its texture is compact, its fracture hackly, and it is susceptible of polish. It is ductile and malleable, and when fused, crystalizes in octahedrons. It melts below a red heat, and suffers no change in air.
