OP SEVERAL PARTS OP WESTERN ASIA. 3&1 



" My tour extended both into Asia and Europe, and I formed a 

 general idea of the geology of the regions through which I passed, 

 so as to be able to give it in a few words. From the chains of the 

 Olympus to the great Balkan in Rouraelia, there is a regular series 

 of rocks. The Marmora produces no changes, nor any difficulty in 

 the study of the formations, especially as the Princes' Islands con- 

 tinue the gradation of the series." 



After describing the rocks of Olympus and northward, as pre- 

 viously given, ]VIr. Van Lennep adds : 



" At Constantinople, and along the western side of the Marmora, 

 the prevailing rock is secondary limestone, full of shells of various 

 species, bivalve and univalve. (No. 627 is an example of the for- 

 mer.) So far as I know, all the other rocks are of volcanic origin. 

 And similar to the above description are all the rocks of Roumelia, 

 so far as I have been." 



Mr. Van Lennep adds, in respect to a region southeast of 

 Smyrna, in the ancient Pamphylia, some statements that may be 

 interesting, though derived from European travellers. He was 

 informed, that, 



" In Pamphylia, there is a gradation from the seashore, to a dis- 

 tance of several days' journey inland, of shells, gryphites, corals, &c. 

 Large plains are entirely underlaid by fossil coral, while the coast 

 westward is entirely composed of primary limestone. Another 

 traveller brought me, a few days ago, oysters, pectens, &c., which 

 he found in an elevated plain six days' journey from Smyrna in a 

 southeast direction. I hope, myself, to take a trip next fall from 

 Macrito Satalia along the southern coast of Asia Minor; and, while 

 I attend principally to missionary labors, I shall endeavor not to for- 

 get the interests of science." 



No. 471 is a specimen of genuine bituminous coal, obtained 

 by Mr. Perkins at Heraclea, some seventy or eighty miles east of 

 Constantinople, on the south shore of the Black Sea. I am told 

 it occurs there in considerable quantity, and if it does, it must be 

 invaluable, both from its proximity to the capital, and its excel-
