The coal, No. 4, from " Roberts' Seam," Muhlenburg County, Ken- 

 tucky, has specific gravity =1 26 ; No. 9, from " Wolf Hill," Daviess 

 County, Indiana, has specific gravity = l - 275. 



No. 13, the Breckenridge cannel, of Hancock County, Kentucky, 

 consists, when the ash is excluded, of Carbon 82 - 36, hydrogen 7 84, 

 oxygen 7 05, nitrogen 275, and the Bog-head cannel of Scotland, called 

 also torbanite, contains Carbon 8039, hydrogen 11-19, oxygen 7*11, ni- 

 trogen 1-31. 



The " Mineral Charcoal " of coal beds differs little in composition 

 from ordinary bituminous coal ; there is less hydrogen and oxygen. 

 Rowney obtained, for that of Glasgow and Fif eshire, Carbon 82 - 97, 

 74-71 ; hydrogen 334, 274; oxygen 759, 767; ash 608, 14 86. The 

 nitrogen is included with the oxygen ; it was 0'75 in the Glasgow char- 

 coal. Exclusive of the ash, the composition is Carbon 88'36, 87 '78 ; 

 hydrogen 3 56, 3 21; oxygen 7 - 28, 9*01. It has a fibrous look, and 

 occurs covering the surfaces between layers of coal, and has been ob- 

 served in coal of all ages. It is soft and soils the fingers like char- 

 coal ; one variety of it is a dry powder.
