seeaneeee lee evaporative trials were performed by burning about two tons of each kind of coal, under a boiler capable of evaporating 15 cubic feet of a 
water per hour. ia 
The ultimate analysis of coal No. 1, was effected by burning in contact with scale oxide of copper—2. Analysis by scale oxide, as in No. 1.—3. Analysis 4 
by same material as above. The heat expended on gases is calculated from the mean result of several other coals of similar constitution —7. No evaporative ™ 
trials of Osage coal or of bitumen have been made.—It appears that on an average, the first six varieties of coal expended in evaporating water from the boiler 3 
85°35 ; and on the products of their combustion 14-65 per cent. of their whole heating power. Both the sum and the number of differences between the practical > 
and the calculated evaporative powers, affected by the positive sign, are seen in the last column to be the same as those affected by the negative sign.
