hrgil, in which are catseved small roiindish nipples of carbonated 

 lime, quartz, sulphurated iron,ixc. of a brown colour. Bohner-

10. Compact mercury, in brittle, shining masses, very often 

 irlsated with the finest colours, easy to be cut, and susceptible 

 of a very fine polish. \y\ii\\X.Ci\ Slaal-eiz. 



11. Sn'phurated mercury in brown masses, dividing itself by 

 curvilinear laminae, an inch and half thick, imitating the testa- 

 ceous form, containing plenty of iron and argil. Braiin-erz. 



12. Sulphurated mercury of a coarse and close grain, of a 

 blackisli brown, strewed with lenticular sulphurated iron, con- 

 taining- bitumen ; vervrare. A variety of the above. 



13. Compact sulphurated mercury, mixed with shells which

 Coralien-erz. 



14. Sulphurated mercury, less compact, the shells of which 

 have a black colour owing to the bitumen mixed with it, not so 

 rich as the foregoing. 



15. Sulphurated mercury, less shelly than the foregoing, 

 holding little bitumen, formed partly of freestone and of sulphu- 

 rated iron called Cora lien waiide. 



l(j. The same as the foregoing, not so rich in mercury, al- 

 most Idack bituminous, having for its base carbonated lime, and 

 the shells remaining in this state after calcination without losing 

 their forms. 



17- Crystallized sulphurated mercury in octohedra or in py- 

 ramidated tetrahedral prisms of a liveiv red, sometimes irisated, 

 in a species of argillaceous geodes in which native mercury is 

 often found. Cryilcdli^irle zinoher. 



IS. Globular schistous sulphurated mercury, in round or oval 

 masses weighing from two ounces to four or five pounds, the 

 nucleus of which is often sulp!uu-ated iron. Kiesel hougel. 



19. Sulphurated mercury, prismated or octohedral, or rather 

 amorphous cubes, of an extremely bright red, u'.iited with hy- 

 drogen, giving out a smell of hydro-suljjhuret v/hen it is pounded, 

 and causing slight detonations when we triturate tlie transpa- 

 rent crystals in a glass mortar. This variety has for its matrix 

 a quartzo-argillaceous biack schist, emitting (ire with steel.
