are angular, in general small, some of which are 

 of a blood red, and others of a grass green. This 

 k beautiful rock, which resembles in its paste the 

 rock called lard-stone, used by the Chinese, was 

 discovered by M. Rampasse in Corsica, in the 

 department of Golo. I could have wished to have 

 given it a more exact locality, on account that it 

 would be highly interesting to work this beautiful 

 steatitic bricia : but M. Rampasse constantly re- 

 fused it. 



" 2. Steatitic bricia of Monte Nero. The 

 steatitic bricia of Monte Nero is found in the lit- 

 tle torrent of Orsara, in Liguria. Instead of a 

 base wholly talcous, like the preceding, it consists 

 of a calcareous base of a cherry red, with a gra- 

 nular and scaly fracture, and only its spots are 

 owing partly to pebbles of serpentine of a pista- 

 chio green, and partly to some globules of laminar 

 diallage. It sometimes happens that the spots of 

 serpentine are surrounded with white rings, which 

 farther relieves the richness of this beautiful bri- 

 cia, which was discovered by M. Viviani, a learned 

 mineralogist*. It is to be regretted that its site 

 is not yet known, it being only found in detached 

 masses, in the torrent of Orsara. "f
