and Reduction of Iron- Ores, 
ference to express the quantity of oxygen removed from the 
ore during the operation. The following may be considered as 
a near approach to the constituent parts of the richest and den*^ 
sest species of the Lancashire hematites. 
Iron, * - 640 
Oxygen united with iron, 245 
Earthy matter, - 5.0 
Water, - - - 6.5 
100.0 
The proportion of oxygen united in this analysis, is undef 
40 per cent. 
I shall feel much gratified if these remarks lead to farther 
investigation ; so that those who are interested in the subject, 
may not only be furnished with an accurate result, but also 
with a method by which the same may be definitively ascertained.
