The 



IB vessel, containing the water, is removed from the end of the branch tube, and the latter fitted with a short 

 biece of thick walled rubber tubing, to serve as a collar. The gas pipette is restored to its position, with its funncl- 

 .haped mouth pressing against the rubber collar ; this can easily be effected by means of raising the pillar support 

 >f the table. The connection can be made air-free and air-tight without difficulty. The dissolved gases in the 

 vater previously transferred to the laboratory flask F can be extracted in the ordinary way and stored in the 

 ;as pipette D. When this operation is completed, the gas pipette is removed and attached to Adeney's apparatus 

 or experiment and analysis.
