Examination and Analysis of a Coal from Glierra Punji, received 

 from Messrs. GriLMORE and McKilligan. — By H. Plddlngton, 

 Esq. Curator, Museum of Economic Geology. 



This coal is, on one fracture, a fine bright glance coal. On the 

 cross fracture it is hackly and resinous, and wherever faint lines of 

 stratification can be traced they are again crossed by lines almost 

 perpendicular, though the coal shows no tendency in its fragments to 

 divide cubically, but rather in beds and thick laminae. 



When either the powdered or solid coal are exposed to heat in a 

 closed crucible, it is found that they swell up in coking to a curious 

 bright black puffy and froth-like mass, which fills the whole crucible , 

 and is exceedingly tender and brittle. This singularity distin- 

 guishes it from all other coal, of which we have any record avail- 

 able here. 



It crackles and flies a little in the forceps, and then flames and 

 burns up in long gas-like jets. 



The smell of the smoke is that of good Newcastle coal, and has 

 nothing disagreeable or peaty about it. 



Its Sp. gravity is, 1 .24 



Its constituent parts are, 



Water, 00.85 



Gaseous matter, 66.00 



Carbon, 32.65 



Ash (dark grey), 00.50 



100.00
