24 Bone's Geological and Miscellaneous Observations. 



9nd chalk, nearly like the deposit of the Parisian tertiary 

 basin, except the accidental gypsunn of Mont Martre. Yet 

 there are many points of difference. 



After this I visited the south oi Germany, and saw the 

 salt deposit of Wirtemberg under the Muschelkalk in the 

 red marl. Thence I passed to the German Alps, and from 

 Switzerland to Hungary. I found that the limestone Alps 

 contain Zechstein. red marl with salt, muschelkalk, green 

 sand, and hard chalk, — iron pyrites occurs in the green sand. 

 The red marl is often very different from that of Germany, 

 and hke a calcareous grauwacke alternating with blackish 

 or grayish marls, and indurated marls with impressions of 

 ferns. (See my memoir in the Journal des Mines.) This 

 deposit forms a great part of the Carpathians, and of the 

 salt formation of Transylvania. In this last country I re- 

 mained four months, where I saw the old transition porphy» 

 ry with small vems of gold ^c. at Kapnick, Naggag, tire. 

 Every where marks of elevation and alteration of rocks 

 like grauwacke. At Vorospatak grauwacke impregnated 

 with gold, not only around gold porphyries, but also sup- 

 ported and elevated by porphyry with which it is intermix- 

 ed. I found gold in carbonized wood in recent grau- 

 wacke ! 



From the Bukowina to Carlstadt is a great trachytic 

 conglomerate district with many interesting tertiary depos- 

 its in the southern plain at the foot of the Wallachian chain, 

 Sec. This winter I expect to complete a geological map of 

 this district, and hope to throw some light on many inter- 

 esting points which have been, not at all, or but ill descri- 

 bed. In the Bannat, sienite forms in the transition rocks, 

 ganglion like dykes, and at the contact of this sienite with 

 beds of limestone, the latter is granular, containing copper 

 and iron with garnet, amphibole, tafelspar &c. which 

 have been generated between the limestone and the 

 sienite. 



Being desirous of going into Sclavonia, I was compelled 

 to stop having had the misfortune to be poisoned by my 

 servant and coachman with the datura stramonium. On 

 recovering my reason, I found that I had been robbed of 



not so familiar to him as the French, will be overlooked in the interesting 

 results it contains, and the indefatigable ardor it evinces.
