Prof. H. How on Oil-Coal. 77 
The Oil-Batt appears to be decidedly a shale, and a specimen 
from Bear Brook, Frazer Mine, gave these results: 
Volatile matters, - - - - - 30°65 
Fixed carbon, - - 10:98 
cox - + + +  6847==10000 
roceed to compare the Torbane Hill mineral, and the 
“Albert coal.” A specimen of the former, examined at the 
time of the trial before mentioned, in 1853, gave me— 
Volatile matters, 71°17 Carbon, 66°00 
Fixed carbon, 65 Hydrogen, 8:58 
sh, 21:18=100°00 Nitrogen, 0°55 
Sulphur, 0-70 
Oxygen, 2:99 
Ash, 21:18==100°00 
In a recent examination, a specimen of “ Albert coal” gave: 
Volatile matters, 54°39 Carbon,* 87°25 
Fixed car 45°44 Hydrogen, 9°62 
0°17=100°00 Nitrogen, 1°75 
sh, O17 
Oxygen and S, 1:21=100°00 
These results I place in a table with corresponding data ob- 
tained from bituminous and cannel coals, the i gravities
