Extract

The very rare barium zeolite edingtonite was described by W. Haidinger (1825), and named in honour of Mr. Ed.ington. Haidinger's material consisted of small crystals on thomsonite from Dumbartonshire. An analysis by E. Turner indicated a calcium aluminosilicate, but there was a loss of 11·22 %. The crystals (sp. gr. 2·71) were morphologically tetragonal, with the prism m(ll0) and sphenoids p(111) and n, and an axial ratio c/a = 0·6725. A. Breithaupt (1832) gave the name 'Antiëdrit' on account of this Symmetry,
