In neither of the series was the critical concentration perfectly 
reached; hence the discrepancy, which is, however, small, between 
the results. The critical opalescence was, however, clearly to be 
perceived. In both cases the experiments had to be broken off on 
account of the appearance of a leak in the piston of the hydro- 
static press. 
For a comparison we give the following results obtained in a 
Cailletet tube, which have not yet been published until now:

Above this pressure the plaitpoint temperature increases greatly ; 
at a pressure of 1100 kg. per em* the mixture remains homogeneous 
at every temperature, at least no turbidity sets in up to at least 
85°, but a decrease of 10 atm. in the pressure suffices to bring us 
back to the heterogeneous region. When the temperature rises still 
higher, we seem to reach the maximum pressure of the plaitpoint 
line, where the branch which comes from the lower critical end-
