MODE V, GRANITE* 



A. D. 400, may be found in the same work. It 

 belonged to the Serapeum, which was a noble 

 library, much reduced by Diocletian, when he 

 ordered the Egyptian works of alchemy to the 

 flames*. 



The same, with large patches of siderite, in the 

 sphinxes of the museum at Paris. 



The same, running in veins through grey gra- 

 nite. 



Grey granite of Egypt, consisting of felspar,

 from its resembling the colours of a starling. 



Black and white granite, consisting chiefly of 

 siderite with quartz, and a little felspar. 



Dull green granite, of green siderite, with a 

 little quartz and felspar. 



Yellowish granite, of granular quartz, yellowish 

 felspar, and greenish siderite, in large plates with 

 metallic lustre, from Zillerthal. 



Red granite, of felspar, quartz, and hornblende, 

 from Peterhoff in Russia.

* Oros. vi. 15. Some theoretic French writers had inferred that 

 the Egyptians were negroes (in opposition to the mummies them- 

 selves), because they thought the Sphinx has negro features. Abd- 

 allatif, p. 179, tells us it was originally painted red, and the colour 

 was still fresh in his time ; nay Grobert, p. 32, observed a yellowish 

 tinge in parts not rubbed.
