APPENDIX. 



the globules of which, of much greater size, are almost en- 

 tirely white, owing to the predominance of the felspar of 

 that colour, and the almost total absence of hornblende, of 

 which only very slight traces can be distinguished. White 

 globules, like those on the black ground spotted with white, 

 of which this granite is composed, produce an effect as re- 

 markable as it is extraordinary. The arts might reap great 

 advantage from it in the formation of certain monuments j 

 which would be the more attractive of notice as the Greeks 

 and Romans, so solicitous of employing the most curious 

 granites, never knew this species. As, according to M. Ma- 

 thieu, the largest blocks are of this variety, they would con- 

 sequently furnish the most considerable masses ; in order to 

 transport them, all that would be required is the making a 

 road practicable for carriages, from Mount Sainte Lucie to 

 the Gulf of Valinco. 



Some laminae of mica, of a bright brown, are seen in small 

 patches, in certain parts of this granite. 



No. 3. Another variety, remarkable on account of the 

 ground of the stone, which is of much deeper colour,, owing 

 to the greater abundance of hornblende, and to its particles 

 being more divided, and more equally mixed with the granu- 

 lated felspar, which has received a tint from it of greenish 

 black, that gives the stone, which is hard and receives a very 

 beautiful polish, rather a grave appearance. The globules in 

 general are of inferior size, and distinctly marked, and the 

 lightly greenish tint which shades their white circles harmo- 

 nises with the ground of the stone. 



No. 4. T know not whether or not we ought to consider as 

 a fourth variety that in which the globules are of equal size 

 with those in the preceding, but in which the ground is dif- 

 ferent ; being more rich in felspar than in hornblende, and 

 speckled with white and black in a very distinct manner 

 and without being mixed, so that the white specks predomi- 

 nating, the ground, far from being so harsh as in the pre-
