ANALYSIS OF SPECULAR IRON ORE. 



The specimen analyzed was gotten by Prof. E. A. de Schweinitz, 

 from the neighborhood of Salem, in Forsyth county. It crumbled 

 with comparative ease, and had a specific gravity of 4.719. The 

 analysis resulted as follows: 



Fe203. 99-30 



SiOa - - .85 



100.15 



Tests were made for sulphur, phosphorus and manganese, but 

 none could be detected. The specimen was, therefore, of a very 

 high grade of purity. I. H. MANNING.
