This sample consists of anhydrous sesquioxide of iron, specular iron ore, mixed with 30 per cent. of quartz and earthy matter. It yielded:—

Sesquioxide	70 per cent.
Silica	22 per cent.
Earthy matter	8 per cent.

This is equal to 49 per cent. of metallic iron. It is, therefore, if in quantity, a valuable ore.
