It unites with fulphur by grinding, and 
then produces a black powder, called 
^thiops mineralisy which fublimes into a 
red llriated body, called faditious cin- 
nabar. 
k. The fulphur is again feparated from the 
quickfilver, by adding iron or lime, to 
which the fulphur attaches itfelf, leaving 
the quickfilver to be diftilled over in a 
metallic form ; but if a fixed alcali is added 
to it, fome part of the quickfilver will re- 
main in the refiduum, and in that cafe 
^makes a liver of fulphur,.
