In a paper read before this Society in 1904, dealing with a number of new minerals from the Binnenthal dolomite, Mr. R. H. Solly described under the name of bowmanite some small, honey-yellow crystals belonging to the rhombohedral system and forming either hexagonal plates or combinations of rhombohedron and basal planes of octahedral habit. Mr. Solly afterwards handed over the small amount of available material to me for further examination.
