 It is not improbable, that this oxicarburettcd hidrogea 

 gas is composed of an atom of carbon, an atom of oxigen, 

 and an atom of hidrogen. If this supposition be well- 

 founded, the proportion of oxigen must exceed a little 

 what we have obtained by our analysis. This would pro- 

 bably have been the case, if we had founded our analysis 

 upon any of the succeeding experiments, rather than the 

 first of the preceding table. 



The preceding experiments, I flatter myself, entitle us to Conclusions, 

 conclude, that two gaseous compounds of hidrogen and carbon 

 exist. To the first we may give the usual name of car- 

 buretted hidrogen ; to the second the name of supercarbu- 

 retted hidrogen, as it contains very nearly twice as much 

 carbon as the first gas does. There exists also a gaseous 

 compound, consisting of oxigen, carbon, and hidrogen; 

 but it differs in its properties from all other inflammable 

 gasses hitherto examined. The reason why the inflammable 

 gasses from vegetable and animal substances differ so much * 



from each other is, that they usually hold an oil in solution, 

 and are mixed with variable quantities of carbonic oxide 

 gas. ^
