312 DESCRIPTIVE MINERALOGY. 



LOCALITIES. 



Putnam County. A mineral closely resembling that described above, is found in a dark 

 coloured serpentine at Brown's quarry, three miles northwest of the village of Carmcl. It 

 has a specific gravity of 2.746. 



Orange County. A mile south of the village of Amity, there is a mineral associated with 

 chondrodite and serpentine, which bears a close resemblance to schiller spar. It has a dark 

 green colour, a laminated structure, and a metallic lustre. The laminre are translucent. 



There is still some uncertainty in regard to this mineral, and I therefore hesitate to refer to 

 the same species the metalloidal diallage of Haiiy. It has already been stated that Dr. Koh- 

 ler, after an examination of several varieties of diallage, arrived at the conclusion that metalloi- 

 dal diallage, bronzite and hypersthene, are subspecies of pyroxene, while schiller spar and 

 anthophyllitc belong to the schiller spar family. These views in regard to the two latter mi- 

 nerals are adopted by Mohs and Jameson. Dr. Thomson gives a detailed description of the 

 mineral here introduced, which agrees very well with the specimens found in Putnam county. 



According to Prof. Shepard, schiller spar is found associated with serpentine and kcrohte 

 at Blandford in Massachusetts. 



ANTHOPHYLLITE. 



[From the Greek av^os, a flower, and (puXXov, a leaf.] 



Anthopliyllite. Uauij, Ckavcland, Beudant and Slupard. — Prismatic Scliiller Spar. Jameson. — Prismatischcr 

 Schiller-Spath. Mohs. — Anthophyllite, Strelite and Karstin. Thomson. 



Description. Colour yellowish grey and clove brown. Streak white. It occurs massive, 

 the mass consisting of crystals or crystalline fibres, often disposed in a radiating form ; these 

 may be cleaved parallel to the lateral planes of a rhombic prism of 125° and 55°, and both 

 its diagonals ; but the latter are not brilliant {PhiUips). Fracture uneven. Lustre pearly, 

 inclining to metallic, especially on the perfect face of cleavages. Translucent on the edges. 

 Hardness from 5.0 to 5.5. Specific gravity from 2.940 to 3.155 {Tho?nsoii); from 3.00 

 to 3 .30 {Phillips). Infusible before the blowpipe per se ; with borax, it fuses with difficulty 

 into a glass coloured by iron. 



Composition. Silica 56.00, alumina 3.00, magnesia 23.00, lime 2.00, oxide of iron 

 13.00, oxide of magnesia 4.00 {Gmelin) ; Silica 57.12, protoxide of iron 13.52, magnesia 

 25.92, lime 1.32, water 1.36 (Thomson). 



Geological Situation. It occurs in primitive rocks. 



localities. 



Putnaji County. This mineral is found in the vicinity of Carmel, but the precise locality 

 is unknown. It is of a greyish or brownish white colour, and has the fibres and cleavages 

 of the prunary form. The lustre is pearly and somewhat metallic. It is infusible by the
