quescing on the surface ; some portions of the surface are entirely 
free from it, while others again are covered with an abundance of 
rust arising from its decomposition. : 
sides the above minerals two others were found, one a sili-

idea to be formed of their composition. » 
The different minerals that admitted of it, were examined 
chemically, and the following are the results: 
ickeliferous fron.—The specific gravity of this iron is as 
already stated, from 7-88 to 7-91. It is not readily acted on by 
any of the acids in the cold; nitric acid, either concentrated or 
dilute, has no action on it until heated to nearly 200° Fahr., when 
the action commences, and continues with great vigor even after 
the withdrawal of heat. “With reference to the action of sulphate 
of copper, it is passive, although when immersed in a solution of 
sulphate of copper and allowed to remain for several hours the 
latter metal deposits itself in spots on the surface of the iron. 
pletely. When boiled with hydrochloric acid the iron dissolves 
with the liberation ‘of hydrogen, leaving undissolved the Schrei- 
bersite ; but by long continued action this latter is also dissolved 
with the evolugion of phosphuretted hydrogen.
