The volumes of the gases in their present state will therefore be 

 seen to agree with those of the materials from which they were 

 formed : we will now proceed to inquire how the respective quanti- 

 ties of materials have individually been disposed of. 



The following gaseous products were formed from the elements 

 of water, sulphureted hydrogen, and hydrogen : —

Weigiit of mixed gas. 



By considering an atom of acid gas to weigh 8-133, we have 

 before calculated that it consists per cent, by weight of 246 sul- 

 phur, 44-26 azote, 24-6 oxygen, and 654 hydrogen.

Hence the weight of 100 cub. in. of acid gas is found to be 35-38 grs. 

 From these data we may calculate the volumes of the different 

 constituents of the mixed gas, and the general view of its consti- 

 tution will be seen in the following tabic : —
