250 Notice of Oriental Minerals. 
7. “From a Corinthian capital in a church.” Granular lime- 
stone. 
From Pergamos. 
1. Marble, made of compact limestone. ‘ Broken from a pillar 
in the amphitheatre.” It bears some resemblance to the Potomac 
breccia, but contains seams and thin veins of a blood-red color, pro- 
duced, perhaps, by an oxide of iron ; nitric acid dissolves it, yielding 
a brisk effervescence. 
2. “ Granite, taken from the walls of the same amphitheatre.” 
The three ingredients which constitute granite, are all present, and 
well mixed, but strikingly different in color. The quartz is white, 
the feldspar a dull red, and the mica pitch black. 
3. “ From a statue in a castle near Pergamos.” A rich, snow- 
white granular marble. 
4. Granite, “ from the castle wall.”” The feldspar is crystalline. 
5. “ From a Corinthian pillar, three feet in diameter, in the castle 
at Pergamos.”’ It looks like the best Carrara marble. 
6. Granite, similar to No. 2—‘“ a common rock between Haivali 
and Pergamos. 
From Smyrna. - 
. Chalk, “ picked up in one of the arena” Of a light gray 
es a little soapy to the touch—is acted on violently by the 
acids, answers all the purposes of chalk, has on one side a little 
oolite, the eggs of which are harder than chalk, and some of them 
are hollow. 
2. Jasper, of the finest quality ; color red, fracture, when recently 
made, is resinous. 
3. Concreted carbonate of lime, ‘near Smyrna,” color dusky 
gray. A cylindrical cavity runs through its centre, which, it is 
probable, was once filled with some ligneous substance, now decom- 
posed and absent. 
4. Stalactite, ‘from the same place’”—of a loose texture, and 
having several short branches. 
. “ From the hill on which the castle stands near Smyrna.” It 
is sienite. The feldspar is crystallized, and strongly resembles adu- 
a. 
6. “From Mount Sipylus, between Magnesia and Smyrna.’ 
Shining argillite, yielding a strong argillaceous odor when ae 
on. Its color is bluish gray.
