86 Mr. West on a 



To separate the gaseous contents of the water, 56 cubic 

 inches were boiled until the quantity of gas received ceased to 

 increase ; it measured 7.95 cubic inches. This was repeated 

 several times, and with larger quantities ; nearly the same pro- 

 portion was obtained. 



When the whole of the gas was separated from a portion of 

 the water, a cubic inch tube, graduated into lOOths, was filled 

 and transferred to a bottle, containing precipitated carbonate 

 of lead; on agitating, under water, an absorption took place, 

 amounting to .50 of the gas operated on. 



The residual gas was treated in the same manner with li- 

 quid potash, the absorption was .16 of a cubic inch. 



That portion which resisted the action of carbonate of lead 

 and solution of potash (.34. C. I.), was transferred to a de- 

 tonating tube, with twice its bulk of oxygen gas, and fired by 

 the electric spark ; after this, the quantity absorbed by further 

 exposure to potash, was .14 of a cubic inch, leaving .20, which 

 I consider as azote. 



It appears, then, that one gallon of the water in question con- 

 tains, of
