ANOTHER NEW METAL. 



ProfefTor TromfdorfF, of Erfurt, has publiflied the follow- 

 ing notice : — " One of my mineraloglcal friend?, whofe 

 name I fha!l make known at a proper time, found lately a 

 particular fubftance which he tranfmitted to me for exa- 

 mination. Though the quantity was fmall, I am however 

 convinced that it is a neiu metal combined with fulphur. 

 The charaftcriftic marks of this metal are : It belongs to the 

 volatile metals : with fulphur it forms a mafs which melts 

 like wax, and which cryftallizes; with fulphurcous acid it 

 gives a reddifli folution ; with nitrous acid and nitro-muri- 

 atic acid it gives a yellowifli folution ; muriadc acid has no 

 aftion on it warm : from acid folutions it is precipitated green 

 by the prufiiate of potafii ; of a fteel gray by tinfture of galls; 

 chamois yellow by hydrothion- ammonia * ; by carbonate of 

 potalh it is precipitated as a white oxide; it is not precipi- 

 tated from its folution by cauftic ammonia, and it is proba- 

 ble that it forms with it a double fait. I fliall obferve in the 

 laft place,. that this new^ fubftance is found in Germany. A 

 further account of it will be publiflied in my journal." 



Erfurt, 

 Jan. 1803. 



* By this term we conceive the author to mean a folution of caibonafe 

 of ammonia, in ccatradiHindioa to pure (cauftic) ammonia, which he af- 

 t.rwards mentions.
