COMBIN4rj9,!(»,9F PXIMJJRI^TIC CAS AND OXIGEN., 



mony, tellurium, and zinc with a white flame, mercury with 

 a red flame. Tin became ignited to whiteness, and iron 

 and copper to redness; tungsten and manganese to dull 

 redness ; plutina was ^c^rc^J^ 9f^i^^ upon at the heat effu- 

 sion of the glass. 



The product from arsenic was butter of arsenic ; a dense, 

 limpid, highly volatile fluid, a nonconductor of electricity, 

 aud pf high specific gravity, and which, when decomposed 

 by water, gave oxide of arsenic and niuriatic acid. That 

 from antimony was butter of antimony, an easily fusible 

 and volatile solid, of the colour of horn-silver, of great den- 

 sity, crystallizing on cooling in hexaedral plates, and giv- 

 ing;, by its decomposition by water, white oxide. 

 - The product from telluriurajjn its sensible qualities, re- 

 sembled that from antimony, and gave when acted on by 

 water white oxide. 



The product from mercury was corrosive sublimate. That 

 from zinc was similar in colour to that from antimony, but 

 was mych less volatile. 



The combination of oxirnuriatic gas and iron was of a 

 bright brown; but having a lustre approaching to the me- 

 taUic, and was iridescent like the Elba iron ore. It volati- 

 lized at a moderate heat, tilling the vessel with beautiful 

 minute crystals of extraordinary splendour, and collecting 

 in brilliant plates, the form of which I could not determine. 

 When acted on by water, it gave red muriate of iron. 



Copper formed a bright red bfowa substance, fusible at 

 a heat below redness, and becoming crystalline and semi- 

 transparent on cooling, and which gave a green fluid, and a 

 green precipitate by the action of water*. 



The substance from manganese was not volatile at a dull 

 red heat; it was of a deep brown colour, and by the action 

 of water becfune of a brighter browQ ; a muriate of manga- 



Resinof cop* 

 per. 



• It b vrorth inquiry, whether the predplt^c from oximoriate of cop- 

 per by water is not a bydratedsubmuriate, analogous in its compositioa to 

 the crystallized muriaieof Peru. This last 1 find affords muriatic acid and 

 water by iteat. - .

 rianc gas, -.vluic that cxbov^ referred to lyiust contain 2.
