400 On the Heat developed in Combustion 



From the result of my experiments, 100 parts of this 

 kind of ether ought to be composed of 



Carbon ......... en 



Free or combustible hydrogen . . . . n.8 



Consequently, combustible substances . . . 70.8 

 Water . . . 2 n. 2

According to M. de Saussure's analysis, as well as from 

 the results of my experiments, 100 parts of pure alcohol 

 of Lowitz, of the specific gravity of 792, at the temper- 

 ature of 1 6 Reaumur, are composed of 



Carbon ........ 42.82 



Free or combustible hydrogen 10.18 



Consequently, combustible substances 53 

 Water 47

Or, reducing the water to its elements, 100 parts of 

 this alcohol are composed of
