11." From Tiberias." This is unquestionably one of the 

 iVagments, which Dr. Clarke, in the sentence, quoted under 

 No. 4. calls " amygdaloidal." It is of a dark brown colour, 

 is very compact, and heavy, — is not operatc'd on by the 

 acids; — is feebly magnetic, and contains a (ew pores, which 

 are filled with a friable carbonate of hme. It is evidently a 

 variety of amygdaloid. 



12. "From the valley of Jehoshaphat." This valley is 

 on the east of Jeiusalem, and the brook Kidron, where there 

 is no water, except during part of the year, runs through the 

 middle of it. The specimen is a pale white granular lime- 

 stone. 



13. " Broken off from the rock over the pool of Siloah." 



14. From the pool of Siloah, where the water makes its 

 appearance the second tidne. The spring issues from a rock, 

 and runs into a silent stream. It lias a kind of ebb and flow. 

 Both these specimen^ are limestone ; the former of a.light 

 gray colour, and the latter white, and might be wrouehl into 

 a very beautiful marble. " Regaining the road, which con- 

 ducts towards the east, into the valley of Jehoshaphat, we 

 passed the Fountain of Siloa, and a white mulb( rry-tree, 

 which is supposed to mark the spot where the Oak Rogel 

 stood." C'larke.) This mulberry-tree is mentioned by 

 Pococke, who remarks, '" near this pool, at a white, mulberry- 

 tree, they say, Isaiah was sawn asunder, by order of Manas- 

 seh, and here, it is believed, ho was buried, under the Oak 

 Rogel." The Fountain of biloam, according to Josephus, 

 is situate in the valley of Hinnom, which is on the south- 

 east of Jerusalen, and was not included within the walls of 

 the ancient city. 



15. " From the grave of Lazarus." It belongs to that 

 variety of Limestone, which Brongniart denominates Chaux 

 Carhonatce Saccaroide. It has a granular texture, bearing a 

 considerable resemblance to that of loaf sugar, and yet its 

 structure is distinctly lamellar. 



16. " From mount Zion." Three specimens of reddish 

 gray siliceous limestone, having a smooth fracture, a little 

 coijchoitlal. On applic ition of the acids, a moderate efFerves- 

 cence is produced, A part of mount Zion, which was an- 

 ciently comprehended by the walls of the city, is now ex- 

 cluded. Jerusalem, according to Dr. Clarke, occupies at 

 present only one eminence — that of mount Moriah. on which 

 Solomon's temple once stood ; and on which now stands a
