COMPONITE, in Mineralogy, one of the zeolite family, in delicate transparent or semi-transparent crystals, which occupy the drusy cavities of the anciently ejected masses on Mount Vesuvius. Its form is an oblique four-sided prism, truncated on its lateral edges, and terminated with an extremely dihedral summit. It was first brought to this country by Lord Compton in 1818.

COMPOSITE Numbers are such as can be measured exactly by a number exceeding unity; as 6 by 2 or 3, or 10 by 5; so that 4 is the lowest composite number. Composite numbers, between themselves, are those which have some common measure besides unity; as 12 and 15, both of which are measured by 3.
