Calculation for Azote. 



€668 cubic inch 'S of oxigen were employed containing Nitrogen c«l- 

 four per cent azote: cuiaieJ.

the total quantity of azote in tiie gas consumed was 106'72

The whole azote, found after the expe- 

 riment, was 21 1*80 cubic inches

 fore the experiment only 106-72 cubiq inches

Now, as the whole time was thirteen minutes, if we divide 

 this by the number of gasometers hlltd, it will give us one 

 minute eighteen seconds for each, and the following will be 

 the periods in which the azote was evolved.
