An examination of six specimens, showed the general character of the 

 ore to be amorphous, of a dark brown color, and compact ; some pieces 

 have cavities lined with yellowish brown and dark brown fibrous 

 limonite ; others have rounded quartz grains disseminated through the 

 mass. A portion of the ores has lost part of the water of hydration. 

 The cavities and fractures are fi-equently coated or filled with a brownish 

 red ochreous ore.
