It is evident that the soluble portion is made up largely of 

 olivine, with troilite and liraonite, and small quantities of 

 pyroxene and oxide of nickel ; while the insoluble is chiefly 

 bronzite, with accessory chromite, feldspar and augite. Calcu- 

 lation from the data furnished by the analyses shows that the 

 mineralogical composition of the stone is approximately :
