3. The gas thus abforbed may be recovered from the water 

 the fame in quantity and quality as it entered, by the means 

 pointed out in the firft article. 



4. If a quantity of water free from air be agitated with a 

 mixture of two or more gafes (fuch as atmofpheaic air) the 

 water will abforb portions of each gas the fame as if they were 



toin another gas prefented to it feparalely in their proper denfity.

* According to Mr. William Henry's experiments, water does 

 not imbibe quite its bulk of nitrous oxide; in one or two inftances 

 with me it has come very near it: The apparent deviation of this 

 gas, may be owing to the difficulty of afcertaining the exaft de- 

 gree of its impurity. 



t About --% of nitrous gas is ufually abforbed; and J^- is re- 

 coverable : This difference is owing to the refiduum cf oxygen in 

 the water, each meafure of which takes 3^ of nitrous gas to fatu- 

 xate it, when in water. Perhaps it may be found that nitrous gas 

 ufually contains a fmall portion of nitrous oxide.
