68.543 parts of sesquioxide of iron contain 47.98 parts of metallic iron. 
The preceding six ores are all very good iron ores, and valuable for 
manufacturing purposes if procurable in sufficient quantity. With regard 
to Nos. 26 and 80, it is to be remarked that the yield of metal will be 
increased by an intermixture with the manganese, reducible from the ses- 
quioxide of manganese, which forms with the iron an alloy, valued very 
highly by some iron-men as being particularly adapted for the manufac- 
ture of a superior quality of steel. 
The following table shows, at a glance, the richness and comparative 
value of the ores:

The absence of sulphur and phosphoric acid in these ores is a further 
recommendation for smelting purposes, as the presence of these impuri- 
ties is apt to injure the quality of the iron.
