Barite has been so much enriched by the splendid finds inEngland that perhaps in color, solidity and effective combinations(though defective in crystallographic variety) it stands well upamong the most decorative of the mineral groups. In the BementCollection it is represented by one hundred and seventy-nine speci-mens. Among the Cheshire examples note 15890, also Bucking-ham, Va., (16040); De Kalb, N. Y.
