Notice of Oriental Minerals. 253 
11. Disintegrating porphyry, comprising crystals of white feldspar, 
which crumble between the fingers—also rounded masses of the 
same substance. 
12. Granular limestone, hard, and susceptible of receiving a fine 
polish. 
13. Agaric mineral? Acted on by several of the acids—has 
nearly the whiteness of chalk. 
14. A fragment of a beautiful red jasper. 
15. Concreted carbonate of lime, belonging to the stalactitic va- 
riety, and broken, apparently, from the side of a stalactite. 
16. Granular limestone, of a gray color, covered on one side with 
perfect triangular pyramids of dog-tooth spar. 
17. Limpid quartz, with carbonate of lime. 
The box contained twenty four specimens besides these, from the 
same island. Most of them were decidedly carbonates of lime, of 
the different varieties. 
From Rhodes. 
1. Calcareous matter deposited on a shell. 
2. Reddish calcareous sandstone, evidently oolite, similar to the 
Portland building stone. 
From Malta. 
1. * Broken off from a column ten or twelve feet high, and in 
some places a foot in diameter.” Manifestly part of an enormous 
stalactite. 
2. “St. Paul’s cave, three miles from Velletta.” Light gray 
compact limestone, holding shells in different states of decomposi- 
tion. It might perhaps be called zndurated marl. 
3. “Near the centre of the island.” Much like No 2, except 
that it is friable. It answers for chalk, leaving a distinct mark on 
wood. 
From Syra. 
1. Magnetic oxide of iron, black and red. This is a rich ore, 
and might if it exists in sufficient quantities, be worked with profit. 
I have seldom seen an iron ore, which attracted the magnet more 
powerfully. 
2. An aggregate of mica and crystallized hornblende. 
3. Talcose slate, with a few particles of carbonate of lime.
