 t«'o proportions, one of which is doubU? the other: and as 

 100 pa>-ts of carbon arc combined with 'iSl'Cs? of oxigen

of inflamma- , . i ,. ,, • ■ i 



ale -Mssce. Efasses han given the lollowino particulars respecting car- 



bnretted hidrogen gas. 100 cubic inches of carburetted 



hidrogtn gas consume 200 c. i. of oxigen gas, and form JOO 



c. i. of carbonic acid gas: 100 c. i. of olefiant gas consume 



300 c. i. of oxigen gas, and fora) 200 c. i. of carbonic acid 



gas. By a very smij^Ie calculation we tind, that 100 parts 



of carbon combine with l6'7597 of hidiogen at a minimum, 



and precisely twice as much at a maximum. We see by the 



analysis of sulphuretted hidrogen gas, already mentioned, 



that 100 parts of sulphur combine with 6'6& of hidrogen. 



If from these data we endeavour to calculate the degree of 



oxidation of sulphur that answers to the gaseous oxide of 



carbon in the following manner, 16-7597: 125*818: :6'66: 



49*997, we perceive, that there is a point of oxidation of 



sulphur, in which 100 parts of sulphur are combined with 



50 of oxigen very nearly. 



Snlphuretted Qj^ examining Mr. A. Berthollet's experiments on sul- 

 iQuriatic acid. . . . , ^ 



phuretted muriatic acid, if I may be allowed the term*, we 



see, that 100 parts of sulphur had condensed 204of oximu- 



riatic acid, containing 47*67 of oxigen. In the experiments 



of Messrs. Bucholz and Gehlen care was taken to combine 



with the acid the greateft quantity of sulphur possible; and 



100 parts of sulphur yielded 211 of the mixture: so that 



100 parts of sulphur were combined with 25*19 of oxigen 



and 85*91 of muriatic acid. Admitting, that Mr. Berthol- 



let mnft have had 214 parts of oximuriatic sicid combined 



vith 100 of sulphur, and Messrs. Bucholz and Gehlen 107 



f'-'^oxT'Jesof parts combined with the said quantity, we have two oxides 



y'ji[n.ur. of sulphur, one of which is composed of 100 sulphu." and 25 



oxigen, the other of 100 sulpliur and 50 oxigen. Thus the 



coi-n pounds of sulpliur with muriatic acid form a muriate of 



the oxidule of sulphur, and a muriate of the oxide. From
