OOMPAEISON OF CHLORATE AND NITRATE MIXTURES, 525 



obtained by the total combustion of various bodies by potassium 

 chlorate. 



From this we see that the mixture of chlorate and carbon is 

 the most advantageous, weight for weight ; but that the mixture 

 of chlorate and sugar develops a nearly equal pressure, with 

 a relative weight of chlorate less by a seventh. The mixture 

 of chlorate and prussiate is not advantageous, the iron acting 

 as an almost useless inert component, that is to say liberating 

 a relatively small amount of heat. 



8. Let us now examine the results obtained with chlorate 

 and the analogous data relating to the mixtures formed by salt- 

 petre, for equal weights, such as 1 kgm. of the mixtures, always 

 considering total combustion. 



1 Gaseous water.
