NEWCASTLE COAL, 



No, 2. It IS of a jet black color^ giving a dark, brown- 

 ish black streak on porcelain. It is stratified in its struc- 

 ture, and contains an abundance of mineral charcoal, or 

 ligneous fibres changed into coal. It breaks into irregular 



the fracture is strondv resinous, and 



and 



of a deep velvet black color. It is perfectly free from 

 sulphuret of iron. It burns with a 



1 



very 



liant yellow flame, and when distilled, gives forth an 

 abundance of coal gas free from sulphur: 



Specific gravity = 1.320.
