ITALY. LETTER XVI. 233 



Tietra a" Egitto, Pietra nefritica, and I have 

 feen and bought ancient weights made of it. 



7. Bafaltes Orient dis Niger, cryftallis majuf cults 

 albis granjti-formibus immixtis. Entirely fimilar 

 to a lava with great white garnet-like fherl-cryftal- 

 lizations, differing from . 2. only by a greater 

 fize and diftincier form of the cryftallizations. 

 Though fome marble- dealers affured me of i^s 

 being antique, I doubt it, fince it entirely agrees 

 with a black-grey lava of mcnte Albany. 



10. Bafaltes Occidentals Mollior^ thus they call 

 at Rome an antique and Oriental bafaltes, on ac- 

 count of its fofrnefs. Its colour black- grey, with 

 finall little points and fome fmall gloffy fcales. A 

 variety of . 2 ; but I have fubmitted here to the 

 arbitrary difference of the feulptors. 



9. Bafaltes Orientalis Viridis^ green, extremely 

 hard, homogeneous, and compact, without any 

 cryitallizations. Statues made of it in the capitolio 

 et villa Albani. 



jo. Bafaltes Viridis, punElulis cryjtalUnis albis 

 afperfus (bafalte pedocchiofo), green as the fpecies, 

 9; but fprinkled with fmall white cryftalline (herl- 

 points , fcarce. Two columns made of it are faid 

 to be in the church of S. Pudenziana at Rome j 

 but I did not fee them.
