$2 On a new Metal celled Tellurium/ 



16. Tin and antimony produce the fame phenomenon 

 with the acid iblutions of the new metal. 



The precipitate formed by the antimony prove?, in a unk- 

 ing manner, that tellurium is not a difguifed antimony, as 

 has been fuppofed. A folution of tin in the muriatic acid, 

 mixed with a folution of tellurium in the fame acid, pro- 

 duced alfoa black and metallic precipitate. 



17. The oxyde of tellurium, obtained from acid folu- 

 tions by alkalis, or from alkaline folutions by acids, are both 

 reduced with a rapidity refembling detonation, when they 

 are expofed to heat on charcoal. It burns, and is volatilifed, 

 as has been already mentioned. 



18. By heating for fome time this oxyde of tellurium in 

 a retort, it melts, and appears, after cooling, with a yellow 

 ftraw colour, having acquired a fort of radiated texture. 



19. Mixed with fat bodies, the oxyde of tellurium h 

 perfectly reduced by the method above pointed out.
