what was produced in the different periods during the first 

 halt" of the experiment. 



Calculation for Azote. 

 266S cubic inches of oxygen were employed containing 

 four per cent, azof? : then 



100 : 4 : : 2668 : 106-72 

 the total quantity of azote in the gas consumed, was 106-72 

 cubic inches. 



Azote found after the Experiments. 



Total 211-80 cubic inches. 



The whole azote, found after the ex- 

 periment, was - - . 21 1-80 cubic inches. 



Azote detected by the same tests be- 

 fore the experiment only - 106-72 



Increase of azote 105-08 



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

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

 minute eighteen seconds for each, and the fellowing will 

 be the periods in which the azote was evolved. 



Here the increase of azote appears rather greater, viz. 110 



* The apparent deficiency here 4'96 arises from this circumstance, that 

 the separate portionsof oxygen not having been ascertained, this calculation 

 bas been made with the correspoudiiig but smaller portions of expired 



cubic
