on the Alcohol of Sulphur, or Sulphur et of Carbon. 189 



sulphur ; therefore the 5,6 parts of sulphate of barytes, are 

 equivalent to 0,765 of sulphur, which, added to the 0,1224 

 parts of sulphur contained in the 0,24 parts of sulphureous acid 

 gas, make 88,74 parts of sulphur. The sum total of sulphur 

 and carbon is, therefore, 88,74 + 15593 = 104.67. But the 

 quantity of the sulphur of carbon was 105 parts ; consequently 

 there is a loss of ^ per cent. From this experiment therefore, 

 the sulphuret of carbon is composed of 15,7 parts of carbon to 

 84,83 parts of sulphur. 



Exp. 3. 1,175 parts of sulphuret of carbon produced 0,66 

 of carbonic acid gas, = 0,1782 parts (which is equivalent to 

 15,167 per cent.) of carbon; and 0,271 parts of sulphureous 

 acid gas = 0,138 of sulphur. In the superior extremity of 

 the glass tube which contained the oxyd of iron, there was 

 found, in that part of the tube which projected out of the stove, 

 a small portion of sublimed sulphur weighing 0,029. The 

 sulphuret of iron found in the tube afforded, by the mode of 

 estimation above related, 6,06 parts of ignited sulphate of ba- 

 rytes = 0,829 of sulphur ; therefore the sum total of sulphur 

 is 0,829 + 0,29 + OjiS^ = ^i99^ parts of sulphur, which 

 added to 0,1782 parts of carbon, makes 1,1742 parts, or 0,0008 

 less than the weight of the sulphuret of carbon employed in 

 the analysis. 



B. Comparison of the above Proportions of Sulphur and Carbon, 

 in the Sulphuret of Carbon ^ with those which might be inferred 

 from the laws of determinate Proportions, 



The law respecting the combination of combustible bodies 

 between themselves, is that, when two such bodies unite, the 

 proportion in which this combination takes place is such, that if they
