GANOSTIBUTE, ner ich and AIMAFIBRITE are three new min- 
erals from the Moss mines in Nordmark, Sweden, recently de- 
scribed by L. L. Toschai nan (Geol. For. Forh .) Vii, 210 et seq., 
1884).— Manganostibiite occurs with other manganesian minerals _ 
and vse luster; the powder is brownish. It is infusible before 
the blowpipe, and perfectly schible in hydrochloric acid. An 
analysis afforded :—

for which the formula 5MnO, (Sb, As),O, is calculated. 
Aimatolite (from atua ToE1dns, ‘color of blood—the name should 
properly be hematolite or hematolite), Also occurs in cavities 
in the limestones in small crystals of rhombohedral form with 
basal cleavage. The color is transparent and of a fine red like that 
of precious garnet, the powder is brick red. An analysis gave:

Utahite is a supposed new iron sulphate from Eureka Hill, 
Juab County, Utah, described by Arzruni. It forms a va 
brown crystalline crust on quartzite. The individual crystals are 
very minute; their form is a hexagonal prism with rhombohedral 
pe hes on the alternate angles, The cle ee is prismatic; the 
uster silky. An analysis by M. Damour gay
