 BB fuses in thin fragments to a white 

 porcellaneous mass. 



Localities. Rossie and Natural Bridge in 

 Diana, St. Lawrence co., New York ; gene- 

 rally with Specular Iron. 



E. 



Eaglk Stone. Pliny. According to Kir- 

 wan a kind of iron ore, consisting of a 

 reniform crust of the oxide investing an 

 ochreous kernel, which is sometimes loose. 



Earth Flax, Woodward. See Amian- 

 thus and Asbestos. 



Earth -FOAM, Fhillips. See Aphrite. 



Earthy Bitumen. Occurs massive, of a 

 dull, blackish-brown colour, and an earth}' 

 and uneven fracture. It has a shining streak, 

 and is so soft as to receive an impression 

 from the nail. Smell strongly bituminous. 

 Feel greasy. Burns with a clear and brisk 

 flame, emits an agreeable bituminous smell, 

 and deposits much soot. H. 2. S.G. I'lo. 



Localities. — Scotch. Hurlet, near Glas- 

 gow, with Calcite; and in freestone at 

 Binney quarries, near Edinburgh, where it 

 is so abundant that the workmen make 

 candles of it, and use it for domestic pur- 

 poses ; also in East Lothian, Caithness, the 

 Orkneys, &c. — Foreign. Persia, between 

 Schiraz and Bender Congo. The valley of 

 Travers, in Switzerland. The Harz; and 

 near Prague, in Bohemia.

Earthy Cobalt, Phillips, or Asbo- 

 LAN. A Wad, of Avhich oxide of co- 

 balt forms a large proportion. Colour vari- 

 ous shades of brown, ash, and bluish-black. 

 Amorphous, massive, mammillary, botry- 

 oidal, disseminated as a coating, and pul- 

 verulent. The fracture of the massive 

 varieties is earthy and dull, but the streak is 

 black, shining, and resinous. Soils some- 

 what. Yields easily to the knife. H. 1 to 

 1-5. S.G. 2-22.

According to Rammelsberg, the foregoing 



analysis would give the formula (Co, Cu)2 Mn 



+ 4 H for the ore from Saalfeld. 



BB on charcoal does not fuse ; with borax 

 forms a deep cobalt-blue coloured globule. 



Dissolves in cold, strong, muriatic acid, 

 with copious evolution of chlorine, forming 

 a brown solution, which turns blue when 

 heated, and becomes red on cooling. 



Localities. — English. Cornwall, at Huel 

 Unity, Huel Gorland. Alderley Edge, in 

 Cheshire, in red sandstone. — Scotch. Lead- 

 hills and Preston, in Stirlingshire.— /m^-. 

 Roscommon Cliffs, in the peninsula of 

 Howth, near Dublin, in clay-slate.— i'bre?5fw. 

 It also occurs at Nertschinsk, in Siberia; at 

 Riechelsdorf, in Hessia ; at Schneeberg and 

 Saalfeld, in Saxony ; in Bohemia ; Swabia ; 

 Kitzbuchh in the Tyrol ; AUemont, in Dau- 

 phine; the valley of Gistain, in Spain, &c. 



The brilliancy of the streak afforded by 

 this mineral, or which its surface attains 

 when rubbed against a hard body, _is very 

 characteristic.
