Abstract
IN the Scandinavian North, so extraordinarily rich in mines and quarries, there have been found during the last few years a number of new minerals, by which many a mine and even many an inconsiderable opening scarce known in its own parish has become world-famous in mineralogical literature. Several of these finds are of great interest in a systematic aspect—for instance, the discovery of barytite, a new, exceedingly basic variety of felspar containing baryta; of ganomalite, the first natural silicate of lead which has been discovered; of ekdennite, a new mineral containing antimonic acid, from the mines of Langban; and of homilite, a new, beautifully crystallised silicate of boron, containing water, from Brevig. Others again give us a highly unexpected insight into the nature of the chemical forces which are in activity in the interior of the earth—for instance, the Werm-land minerals, manganosite, or protoxide of manganese, and pyrokroiie, or hydrated protoxide of manganese, which afford evidence of a powerful reducing action. The latter mineral has during last year been found at a new locality—the mines of Nordmark.
