carbonate of bismuth. From avery small specimen of it, which I 
have seen, I am led to suspect that it is the same mineral called by 
the Germans lismuth ochre. The colour, fracture, and lustre, are 
similar: The specific gravity is less, being only 3°0755; but the 
fragment examined was much mixed with clay. 
XIN. Carbo-Sulphuret of Mercury. 
- Dobereiner has ‘lately announced that there exists a native com- 
pound of mereury and sulphuret of carbon. He calls it guecksil- 
bererz (ore of mercury).. I should not be surprised if this were the 
commen ore of Idria, called quecksiller-lebererx (hepatic ore of mer- 
cury); for Klaproth found this ore to contain both sulphur and 
carbon, nearly in the proportion in which they exist in sulphuret of 
carbon. .Dobereiner says, that when the ore is distilled, sulphuret 
of carbon is obtained. He informs us that sulphuret of carbon 
unites with all the metals, and forms a new class-of bodies.
