It is this adhesion of the C0 2 to the walls of the vessel that 

 makes it possible to obtain a disappearance of CO under the 

 discharge up to the point where the discharge ceases, even if 

 there is no cooled portion on which the gas may condense (see 

 par. 14, loc. cit. vol. xli. p. 6SS). The absorption of the gas

is very much slower than if there is a cooled portion, because 

 there is a larger concentration of the 00 2 and the reverse 

 reaction proceeds more rapidly ; but it does not stop, in the 

 vessels that have been used, until more than 0*1 mm. of gas 

 has been removed. In the experiments of fig. 5 much more 

 than this quantity of gas had been absorbed in the vessel, and
