seams alternate with beds of slaty clay and common clay, 

 sandstone, limestone, sand, &c. They are often associated 

 with vegetable organic remains, in slaty clay, sometimes 

 also with shells. Generally there is some hexahedral or 

 prismatic Iron-pyrites intermixed along with them, and 

 they are traversed by veins, generally narrow, of hexahe- 

 dral Lead-glance. 



4. The bituminous Mineral-coal is so universally distri- 

 buted, that only a few localities can here be mentioned as 

 examples. Bituminous wood is found in considerable quan- 

 tity in Iceland, and is- called Surturbrand ; in the Meissner 

 mountain in Hessia, in the Westerwald, at Voitsberg in 

 Stiria, at Bovey in Devonshire. Earthy coal is found at 

 Merseburg, HaHe, Bernburg, at Eisleben in Thuringia. 

 Moor coal occurs in the northern districts of Bohemia, as 

 at Elbogen, Carlsbad, Teplitz, &c. also at Kaltennordheim. 

 Common brown coal occurs in immense quantities on the 

 river Sau, and on the foot of the Schwamberg Alps in 

 Lower Stiria, at Judenburg, Leoben, and other places in 

 Upper Stiria, in the Meissner in Hessia. Pitch coal is 

 likewise found in the Meissner, at Planitz and .Zwickau 

 in Saxony, in Silesia, on the Rhine, in France ; slaty coal 

 at Potschappel in Saxony, in Silesia, in Westphalia, but 

 particularly at Newcastle, Whitehaven, and other places 

 in England and Scotland. Foliated coal is raised at 

 Potschappel, at Lobegun near Halle on the Saale, also 

 at Haring in the Tyrol, at Liege ; coarse coal at Neustadt 

 in the Hartz, at Potschappel in Saxony, in Silesia, &c. ; 

 and the cannel-coal particularly in Lancashire and Shrop- 

 shire in England, and in Scotland. 



5. The important use of the bituminous Mineral-coal is 

 well known. The cannel-xxjal is worked into buttons, snuff- 

 boxes, &c.
