OF SEVERAL PARTS OF WESTERN ASIA. 399 



ing westerly from Mount Ararat, and is called the Ararat range. 

 From one of the highest peaks of this range, where it is crossed 

 by the short Erzeroum road to Oroomiah, was taken No. 466 ; 

 which is compact limestpne, with a vein more crystalline. No. 

 467 was probably broken from one of these veins, and seems to 

 be argentine. An analysis gave the following results in one 

 hundred parts.

East of Erzeroum, between that place and Hassan Calleh, is 

 found the argillaceous limestone, or as I rather presume it to be, 

 the marl, No. 445. Limestone continues nearly to the foot of 

 Ararat. No. 444 is a hard porous' variety, appearing as if depos- 

 ited from a spring, from a branch of the Euphrates, eight miles 

 west of Diadeen. No. 443 is a reddish compact limestone, from 

 a point east of Diadeen, and twenty miles from Ararat. Near 

 the west foot of that mountain, occui's the dark-colored lime- 

 stone. No. 441. In the same vicinity was picked up the petrified 

 coral. No. 440. Much further from the mountain, however, dis- 

 tinct vesicular lava, both in rolled pieces and in hummocks, is 

 abundant. No. 442 appears like recent lava, and was found near 

 the convent of Utch Kelasia, thirty miles west of Ararat. Nos. 

 438 and 439 are similar lava from Bayazeed, near the west 

 foot of the mountain. One of these has upon it a coating of car- 

 bonate of lime. No. 229 was taken by Mr. Perkins from the foot 

 of the mountain on its eastern side, several years ago, when he 

 first entered Persia. It has an aspect even more like recent lava, 

 than the specimens on the west side. Indeed, all the specimens 

 confirm, if it needed confirmation, the statement of Prof. Parrot 

 and others, that Ararat is made up of volcanic matter. Some 

 travellers have even described craters, from whence eruptions 

 have some time or other proceeded. But there is good reason to 

 believe, that no eruption has taken place since the commence- 

 ment of human history. Sir Robert Ker Porter says, that a reg- 

 ister has been kept for eight hundred years at the convent of
