CUBICITE. S2i Superimposed, and frequently forming druses, whereas leucite is always singly imbedded. 2. This mineral was formerly known as a subspecies of zeolite, under the name Cubic Zeolite; but Hauy ascer tained that it was a distinct species, to which he gave the name Analcime; that is to say, a body without power, because it is only feebly electricby rubbing. Werner, from its figure, names it Cubicite. 3. Count de Hournon observed, in some specimens from Hartfield Moss, a transition from Cubicite into Prehnite; 5. Chabasite. * Schabasit, Werner.
