From column III. we conclude — 



(1) That a mixture of carbonic oxide and oxygen in the pro- 

 per proportions is heated by combustion in a closed vessel from 

 0° C. to (mean of experiments 1 and 2) 



3033° C. 



In these experiments the variation of the single experiments from 

 the mean was only 4*58 per cent, of the whole increase of 

 temperature. 



(2) That a mixture of hydrogen and oxygen in the proper 

 proportions is heated by combustion in a closed vessel from 0° C. 

 to (mean of experiments 12 and 13) 



2844° C. 



In these experiments the variation of the single experiments from 

 the mean was only^ - 388 per cent, of the whole increase in 

 temperature. 



(3) That a mixture of carbonic oxide and air in the proper 

 proportions is heated by combustion in a closed vessel from 0° C. 

 to (mean of experiments 10 and 11) 



1997° C,
