ON WASHING CAPE BRETON COALS.—POOLE. Q47 
For comparison with the work done in the coal washer, a 
laboratory test was made. An average sample of the coal was 
treated in a solution of Calcium Chloride of 1.40 Sp. Gr., the 
coal of 1.30 Sp. Gr. floated on the solution, and the shale of 
2.04 Sp. Gr. sank to the bottom. Thus separated, the coal and 
shale were thoroughly washed and dried, and severally bore to 
the unwashed material the following proportion :—
