OF SEVERAL PARTS OF WESTERN ASIA. 393 



in the vicinity of the mine, and the statement of Mr. Hamlin, that 

 this is the predominant formation in that region, I suspect the 

 copper to be connected, as it often is in other parts of the world," 

 with new red sandstone. Nos. 415 and 416 are pebbles of sili- 

 ceous slate : No. 417 of flint; and Nos. 418, 419, of jasper, from 

 a vast pile of pebbles on the shore of the Black Sea, near the 

 lignite bed. 



Numerous specimens in my collection were obtained from 

 ancient ruins. They consist of elegant marbles, porphyry, granite, 

 &c., interesting as individual specimens, and to the antiquary ; 

 but since their original localities are not designated, I have 

 thought it would be useless to the geologist to describe them. 

 Many specimens of little importance, obtained from the rocks in 

 place, I pass also in silence. 



The third extensive region of which I wish to give some geo- 

 logical notices, embraces the ancient Armenia and a part of 

 Persia and Georgia. For my specimens and descriptions I am 

 indebted to Rev. Justin Perkins, except two or three speci- 

 mens from Rev. J. L. Merrick. Mr. Perkins is now on a visit 

 to this country, in company with Mar Yohannan, an intelligent 

 bishop of the Nestorian church ; and I have had full opportunity 

 to converse with them respecting the points to which I wish to 

 call the attention of this meeting. I cannot but bear testimony 

 to the strong desire and effort manifested by Mr. Perkins, to 

 collect and transmit specimens and information respecting the 

 countries through which he has travelled. In his journey, for 

 instance, from Persia to the Black Sea, a distance of seven hun- 

 dred miles, over a very rough country, on horseback, and with 

 his wife in feeble health, he contrived to bring along not less 

 than seventy-five specimens of rocks and mineral waters ; and in 

 one instance brought on a fever by Ms efforts to climb a high 

 peak of the Ai'arat range, in order to break a specimen from its 

 summit. His route lay from the city of Oroomiah, on the shore 

 of a large lake of the same name, through Khoy, thence to Bay- 

 azeed, near the west foot of Mount Ararat ; thence to Erzeroum ;
