COMBUSTION OF ETHER AND MBTALS IN OXIMURIATIC OAf. 24 J 



A copper wire does not burn in this gas, but becomes as Copper, 

 soft as lead. 



A brass wire not heated redhot does the same. Brass. 



This gas has no action on lead-wire. Lead. 



A wire of red French gold melted, without throwing out Gold, 

 sparks.' 



Pure silver wire, and iron wire, were not altered in it. Silrer. 



Mr. Stratingh, in verifying the preceding experiments, Brass, 

 prefers making the extremity of the brass wire red hot, to 

 adding a burning coal to it. He could not succeed in burn- 

 ing tin wire. . Tin, 



Pie effected tlie combustion of a very slender copper Copper, 

 wire, the extremity of which was pointed and red ^hot. 

 The inside of the jar was covered with green oxide. of 

 copper. 



A wire of ducat gold did not grow red, or melt, in the Gold, 

 gas, but was slightly oxided. This difference probably 

 arose from Mr. Van Meerten's French gold containing 

 more copper. 



Very slender silver wire melted, aftet its extremity had SiWer. 

 been made red hot. 



Iron wire by itself was not altered : but on adding to its Iron, 

 extremity a wire composed of an alloy of three parts of 

 antimony with one of tin, which was heated a little before 

 its immersion, the iron wire gave out much red vapour, and 

 the inside of the jar was covered with a beautiful red oxide 

 of iron. 



Camphor alone does not burn in this gas: but if a piece Ca^p^jg^, 

 be stuck in the end of a cleft stick, wrapped round with 

 tin foil, and this powdered with metallic antimony, the 

 camphor will begin to burn with a deep red flame. 



Oil of turpentine, or of cloves, poured into this gas, gives Essential oi!i, 

 out some fumes, but very little light*. 



♦ A raj vretted witU oil of turpentine takes fiie in oximunatic gas.
