4. If a quantity of water free from air be 

 agitated with a mixture of two or more ga^es 

 (such as atmospheric *ir) the water will absorb 

 portions of each gas the same, as if they were 

 presented to it separately in their proper den* 

 bity. ,. .

5. If water impregnated with any one gas 

 (as hydrogenous) be agitated .with another 

 gas equally absorbable (as azotic) there 

 will apparcNtlj/ be i)o absorption of the latter 

 gas j just as muph gas being found after agi- 

 tation as was introduced to the water; but 

 upon examination the residuary gas will be 

 found a mixture of the two, and the parts of 

 each, in the water, will be exactly propor- 

 tional to those out of the water.
