354 NOTES ON THE GEOLOGY 



Europe. The first and second classes will first demand our 

 attention. 



We now know enough of the rocks around the Mediterranean 

 to be certain, that these compact and chalky limestones extend 

 through a considerable part of Egypt, thence into the northern 

 part of Arabia, thence through Palestine and Syria to Mount 

 Lebanon and Anti-Lebanon, which are mainly composed of 

 these rocks. Similar rocks occur, also, in the island of Malta ; 

 and the compact variety, at least, in Greece and Asia Minor. Out 

 of the large number of specimens in my collection, I have exam- 

 ined a few analytically ; chiefly, however, with a view to deter- 

 mine whether any of them are dolomitic. 



In No. 15, Vv^hich is the common rock of Mount Lebanon, ac- 

 cording to Mr. Hebard, I found in one hundred pai'ts, by a not 

 very satisfactory analysis, although repeated, 



' Earthy residuum, ....... 1.0 



Carbonate of lime, ....... 61.3 



Carbonate of magnesia, ..... 37.7

 No. 25 lies below the conglomerate and chalky limestone, one 

 mile west of Damascus ; and I found in one hundred parts,

 No. 5 is the rock on which Jerusalem is built ; and it was 

 used in building the Temple of Solomon, some of whose foun- 

 dation-stones still remain, as seems to be made very probable by 

 the researches of Robinson and Smith in that city. One hun- 

 dred parts of this stone gave
