The constancy of the ratio ^, and more especially the small- 



ness of the differences in the fourth column, show that the quan- 

 tity of chlorine diffused is proportional to the quantity of chlo- 

 rine mixed with oxygen in the lower vessel at the beginning of 

 the experiment. 



Working with the mixtures of oxygen and ozone obtained di- 

 rectly by electrolysis, the following results were obtained* : —

The volumes of ozone are calculated on the assumption that the volume 

 of ozone is double the volume of the quantity of oxygen absorbed — that is, 

 assuming the density T658 for ozone. Moreover, whatever be the hypo- 

 thesis, the ratio ~ is not modified.
