in Carniola, at Almaden in Spain, and 



Horzowitz in Bohemia. 



Calstronbaryte, Shepard. This min- 

 eral, fomid at Schoharie, New York, has 

 been proved by Shepard to be merely a 

 mechanical mixture of Heavy Spar, Stron- 

 tianite, and Calcite, and not a distinct spe- 

 cies. The trivial name alludes to the three 

 bases which enter into its composition. 



Calyptolite, Shepard. A Zircon, pro- 

 bably somewhat altered, occurring in minute 

 short, square prisms of a dark brown or 

 greenish -brown colour, at Haddam in Con- 

 necticut, U.S., with Chrysoberyl. H. 6-5. 

 S.G. 4-34.

 politic rock from Canaan, Connecticut.

Cancrinite. Hexagonal. Occurs in six 

 and twelve-sided prisms, sometimes with 

 the basal edges replaced : also thin columnar 

 and massive. Colour white, yellow, green, 

 blue, grey, reddish. Lustre vitreous at the 

 fractu'red' surfaces, greasj^ in other parts. 

 Transparent or translucent. H. 5*5 to 6. 

 S.G. 2-42 to 2-62.

Localities. Of a light rose-red colour 

 in the llmen mountains (S.G. 2-489) ; of a 

 citron-yellow colour at Marunskaja, in the 

 Tunkinsk mountains, 400 wersts from Ir- 

 kutsk, in coarse granite (S.G. 2-454) ; and 

 crystallized and massive in the United States 

 at Litchfield, in the State of Maine. 



Name. After Cancrin, a Russian minister 

 of finance. 



Candite, Bournon. Pleonaste found as- 

 sociated with Tourmaline, &c., loose in the 

 rivers and alluvial district around Kandy, 

 (whence the name Candite,) in Ceylon.

Cannel Coal. Cannel is a corruption of 

 the word Candle, which has been applied to a 

 particular description of Coal, either because 

 in burning it gives out a bright flame like 

 that of a candle, or because, in some places, 

 poor people use it instead of lights. 



It is a bituminous substance, and is sup- 

 posed to have been formed from decomposed 

 vegetable matter in water, in the finest state 

 of division. It differs from the purer kinds of 

 ordinary Coal and Jet, in containing extra- 

 neous earthy matters, which render it 

 specifically heavier than water ; Jet, on the 

 contrary, being lighter. It is hard enough 

 to take a fine polish, and is made into ink- 

 stands, snuff-boxes, beads, and other orna- 

 mental articles. (See also Parrot Coal.) 

 SG. 1-23. Cannel Coal has a resinous glis- 

 tening lustre, and a dark greyish- black 

 colour. It is very compact, breaking with 

 a conchoidal fracture, into irregular or cubi- 

 cal fragments. The Cannel Coal of Lesmaha- 

 gow on distillation yields 40 gallons of crude 

 oil, and 30 gallons of rectified oil per ton. 



It is found in England near Whitehaven, 

 at Wigan in Lancashire, Brosely in Shrop- 

 shire, and Athercliff, near Sheffield ; and in 

 Scotland at Lesmahagow in Lanarkshire, 

 Boghead in LinlithgoAvshire, Gilmerton 

 near Edinburgh, West Wemyss in Fife, and 

 Muirkirk in Clydesdale.

Canoxlnite, Bischof. A mineral consist- 

 ing of the silicates of soda and alumina, 

 and carbonate of lime, from the Miasget in 

 the Ural. There are three varieties found 

 in the granite of Litchfield (Maine, U.S.), 

 consisting of the silicates of soda and alu- 

 mina, with carbonates of lime and soda.
