 ession of the freezing- 



The results, on the whole, show that the depr( 

 point for a stirred solution is about that which would be expected were all 

 the dissolved gas present as carbon-dioxide molecules, and that at the 

 higher concentrations a measurable amount of dissociation takes place. 



Series C, 

 To avoid heating by the coil, now recognized as a disturbing factor, 

 the latter was removed after saturation and the experiment was con- 

 tinued without further stirring. In all the experiments of this series (13) 

 little gas was given off during freezing, even when this was complete. When 

 the freezing-bath was removed gas was given off copiously from the solid 

 ice, which appeared either to hold the gas in a solid solution or to be asso- 

 ciated with a solid hydrate which decomposes on melting.
