OF SEVERAL PARTS OF WESTERN ASIA. 355 



No. 54, from the supposed site of the gai'den of Gethsemane, 

 appears to be an agatized mass of silica, containing a little car- 

 bonate of lime. In one hundred parts I found 



Earthy residimm, ...... 



Carbonate of magnesia, ..... 



Carbonate of lime, ...... 



100.00 

 An argillaceous limestone, one mile west from Damascus, 

 yielded in one hundred parts. 



Earthy residuum, ....... 69.67 



Carbonate of lime, 30.33 



100.00 

 The red compact limestone. No. 89, from Wady el Hareer, in 

 Anti-Libanus, yielded in one hundred parts. 



Earthy residuum, ....... 3 



Carbonate of lime, 97

 No. 29 was broken from the rock a few feet from the cave of 

 Machpelah in Hebron, Avhere Abraham was buried : a spot better 

 identified than almost any other holy place in Palestine. One 

 hundred parts gave, 



Earthy residuum, ...... 0.33 



Carbonate of magnesia, 6.33 



Carbonate of lime, ...... '93.34

 These analyses show us, what indeed we might have expect- 

 ed, that the limestones under consideration have been but slightly 

 dolomitized. That from Lebanon contains, indeed, a large pro- 

 portion ; but it would be desirable to know its precise location 

 before we conclude the whole of that mountain to be as highly 

 charged with magnesia. 



I could have had but little hope of being able to refer to their 

 true place, in the geological scale, these insulated specimens of 

 limestone, collected by different individuals in distant lands. But
