Prof. E. Loomis on the Aurora of 1859. 79 
amounts of oil afforded by some of the above may be taken as 
a good illustration of the point brought forward in this paper. 
Iam indebted for these details to H. Poole, Esq. :— 
In Scotland the Lesmahagow cannel coal gives 40 gallons 
erude oil, and 82 gallons rectified oil per ton. 
t M’Lellan Brook the Fraser Oil-Coal gives 40 gallons crude 
oil per ton. 
At Coal Brook the Fraser Oil-Coal and Oil-Batt together give 
58 gallons per ton.

n. 
The “ Albert coal” gives 100 gallons per ton. 
The “Torbane Hill coal” gives 125 gallons per ton. : 
_ And some picked samples of Oil-Coal from Fraser Mine, tried 
in Boston, U. S., gave no less than 199 gallons of oil per ton.
