OF SEVERAL PARTS OF WESTERN ASIA. 



381 



cian Archipelago, and some places in the western part of Asia 

 Minor. 1 begin with the islands ; from which nearly all my spec- 

 imens were sent by Rev. Dr. Robertson and Mr. Van Lennep. 



No. 369 is granite, or more probably gi-anitic gneiss, from the 

 summit of mount Cythnus, on the island of Dclos ; showing us 

 the probable character of the nucleus of the island. But No. 191, 

 which is the half of a stalactite, five and a half inches in diam- 

 eter, sent by Mr. Paspati, indicates the presence also of limestone. 



No. 384 is highly crystalline limestone from the island of Te- 

 nos ; appearing precisely like highly porous lava. But the 

 cavities are the work of some lithodomous animal ; no relic of 

 which, however, remains. 



No. 378 is an epidote from the same island, and is said to be 

 abundant there. 



The specimen of red jasper. No. 393, is from the island of 

 Egina, and occurs there abundantly in rolled nodules ; and it is 

 said, also, in limestone. 



The red limestone and calcareous spar, Nos. 318 and 319, are 

 the only specimens sent from the island of Samos. 



The delicate chalcedony, shown in Nos. 335, 336, and the jas- 

 per. No. 338, are from Cyprus. The sulphate of iron. No. 300, 

 is from the same island, and is said to be a natural product ; but 

 I suspect a mistake here. No. 635 is slaty gypsum, used for floors 

 in Cyprus ; but Mr. A^an Lennep, who sent it, does not say that 

 it is found in the island. 



The principal summits in the island of Syra, according to Dr. 

 Robertson, consist of a yellowish compact limestone, such as Nos. 

 381, 382 exhibit. He says, that the rocks there are mostly pri- 

 mary, consisting mainly of mica slate, talcose slate, and horn« 

 blende slate, as shown by Nos. 372, 373, 377. The two first spec- 

 imens have pyrope^ associated with them. Beautiful actynolite, 

 (No. 375) is also abundant there ; and the hornblende is some- 

 times of a delicate blue color, (No. 376,) if the specimen be indeed 

 hornblende. The talcose slate. No. 377, shows the talc in a some- 

 what indurated state, such as is common in the talcose slates 

 formerly called transition. And the compact character of the 

 limestone would lead to the conclusion that that rock is of a sim-
