Extract

Mr. Arthur Russell collected in 1930 on Pim Hill, near the village of Harmer Hill, 6 miles north of Shrewsbury, Shropshire, specimens of Triassic sandstone encrusted with minute black crystals. They resemble very closely the material from Mottram St. Andrew, Cheshire, which was described and named mottramitc by Sir Henry E. Roscoe in 1876.1 Mr. Russell pointed out this resemblance and kindly placed his specimens of this rare British mineral at our disposal for investigation.
