COMBINATIONS OF OXIMUKIATIC ACID AND METALS. 



133 



from the analysis of the other two compounds, aurum musivum, 

 and the liquor of Libavius, as 155 to 335, or as 31 to 67- 



The proportions of sulphur in the two sulphurets of iron 

 do not accord with the proportions of oxigen in the oxides, 

 or of chlorine in the chlorine combinations j but I am yet ig- 

 norant of the cause of this difference. 



100 grains of lead, heated with sulphur in a glass tube, 

 afforded, in two trials, 1 ] 55 grains of fused sulphuret. Hence, 

 lead being as 97*2, the sulphur is to the chlorine in the re- 

 spective combinations as 15 Og to 33*8. 



Sulphuret of antimony contains 25*9 per cent of sulphur. 

 Hence, antimony being as 42'5, the sulphur in the sulphuret is 

 to the chlorine in the butter of antimony, as 14*86 to 34'6. 



100 grains of bismuth heated with sulphur afforded 122*3 

 grains of sulphuret. Hence, bismuth being as 67'5, the sulphur 

 is to the chlorine as 15'08 to 342. 



In the following table, the proportions are collected in which 

 chlorine, sulphur, and oxigen combine with several metals j 

 the numbers representing the metals are kept constantly the 

 same, for the greater facility of comparison. 

 Copper 60 H- 32*77 chlorine = cuprane. 

 + 67 '20 ditto = cupranea. 

 + 779 oxigen = orange oxide. 

 + 15*00 ditto = brown oxide. 

 -|- 33 40 chlorine = stannane. 

 -\- 67'00 ditto = stannanea. 

 -1- 15 00 sulphur '= gray sulphuret. 

 + 3100 ditto = aurum musivum. 

 + 7*50 oxigen = protoxide. 

 + 15-20 ditto 

 + 33-60 chlorine 

 + 55-50 ditto 

 + 8*00 oxigen 

 + 13'20 ditto 

 + 33-60 chlorine. 

 97*2 + 33-80 chlorine = plumbane. 

 + 15-09 sulphur = sulphuret. 

 + 7'50 oxigen = yellow oxide, 

 34*5 + 34-40 chlorine = zincane. 

 •h 7*50 oxigen = oxide.
