dysodil of Sicily, but which is distinguished by its containing a con- 

 siderable quantity of pine-tree pollen, and other vegetable remains. 



Since that time it has been found in two other places. The foli- 

 ated serviceable bituminous coal from Geistinger Busch near Rott 

 and Siegburg, to the north of the Siebengebirge, is, although as 

 black as old leather, quite similar to the dysodil, only it is richer in 

 vegetable remains. 



In a fourth similar foliated lignite from Vogelsberge, given me 

 to examine, as were the former, by Ober-Bergrath von Dechen, 

 there may be recognised very beautifully preserved infusorial shells. 

 This substance is also like the black dry sole of a shoe. From these 

 inquiries we see that the species of mineral called dysodil belongs 

 to the infusorial conglomerates, and is evidently a Polirschiefer or 

 Bldttertripel accidentally penetrated by mineral pitch ; whilst at Bilin, 

 Cassel, etc., it appears without any mixture of bitumen. Its colour 

 may be yellow or even brown and black. It nowhere forms exceed- 

 ingly large, but sometimes rather extensive and useful beds. — Pog-
