 of the colonr, from grecnilh-black to velvct-bl.ick ; and 

 likewife uith regard to the fize cf the wliitilh fcUllpar-

 this is moi-c freqnc;itly fceii among the remains of antiquity 

 than the other. 



Mr. Graffenauer, in his mi.;cralogy of Alface, mentions 

 a black poryhyry as occurring at Framont ; and alio as 

 rounded blocks in the river 111. 



In the black Corfican porphyry, the feldfpar-cryaals have 

 a fli'>-ht tint of green, like thofe of the antique green por- 

 phyry. Vcrber makes mention of a Sarilinuip. black por- 

 phyry, and SauflTure of one found in the neighbourhood of 

 Gctui-n, whieli, beiides fmall prifmatic crylhils of feldfpi;r, 

 includes rounded grain; of tranlpaivnt colouriels quart/.. 

 'The latter addition is likewife obfi-rved in a variety of a

 ornamental purpoles. 



yliiliijuc gneit porphyry (porfido vtrde aiitico). This is 

 l\ie ophites of the ancients ; a name derived from fome fup- 

 pol'ed refemblance of this rock, when jiolilTicd, to the Ikiii 

 of a ferpent ; whence, in modern limes, antiquaries have 

 referred the porphyry in qncllion to the magnefian ftone 

 called ferpentine, a ini.\tiirc or which, with primitive lime- 

 ilone, conliitutes the rock called i<crde nnlico. When 

 once conlidered as the fame with the real ferpentine, 

 the name iv/v/c ciitico, of courfe, alfo v.as eqi;ally applied 

 to the green porphyry ; a circumftance which has been 

 produclive of great confufion. There are now but few 

 monuments of ancient art executed in this porphyry to be 

 met with. 



There are fome varieti's of green porjihyry, much re- 

 femb'ling the antique, ftill found in fcveral jiarts of Europe. 

 There is a quarry of it on Monte Vifo, in Piedmont ; 

 which, beiides the feldfpar, contains reddifli grains, fup- 

 pofcd to be garnets. 



TI)e^;-ffH CcrffMn porphxrv, found in the diilrift of Niotto, 

 in Coriiea, has a deep boltle-grern bafc, and fine white feld- 

 fpar cryllals ; anotlier, which enntains fonr.e dark red garnets, 

 occurs in the diilricl of Go'ro in the fame illand. 



Sau.Ture defcribcs the green p'jrjihyry of Geneva, refem- 

 bling the black porphyry above-mentioned, in the figure and 

 colour of the feldfpar and quartz, but differing in its bafe, 

 which is light green and, in fragments, tranihicid at the 

 edges. Botli this and the black take an L-xcellent polilh. 



The green porphyry of the Vcfges has a dark green bale, 

 and contains numerous middle-lized fcldfpar-cryllals of a 

 pale green colour. It is found at La Chevetrev, on the 

 heights of Frefle en Comtc, and made ufe of for orna- 

 Kiental purpofes. In another variety, found not far 

 from this quarry, the feldfpar-crydals are fo preffcd 

 agaiiill each other, that they are ill-formed, and conceal 

 almofl the whole of the bafe. They are manufaClurcd into 

 ilabs for tables, chimney-pieces, &c. and fometimes pafs 

 by tlie improper name of green granite. 



There is abundance of the green porphyry in the Py- 

 renees, where it is known by the old appellation of ophlle. 

 GwKRsflorieJlate, a compound rock, which may be con-

 older than clay-llate, is coniidered as the newell of llsc i.v\k 

 clafs of the trap formation. It occurs in confiderable bed>, 

 and in Sweden whole mountains are faid to confill of it. t;e- 

 veral mining difti-ifts are fituated in this rock, fuch as thofe 

 of Gerfdorf, in Saxony, of lladoUtadt, in Silcfia, and of 

 A delfors, in Sweden.
