The results obtained enable me to soniewlial (elucidate a few dark 

 j)üints oeeuri'iniü,' in litei'afure. From tiie ex|)(M'imenls of Wat,1)kn and 

 Centnekszwer ^) on the sohdnlity of KJ in li(iuid S().^ np to ÜG°, it 

 is obvious that after one of the two liquid layers, which are coexis- 

 tent between 77^.3 and 88", have disappeared, tiie solubility decreases 



and at 96° amounts to no more than 0,58 mol. 





KJ. 



On account of this in their diagram they make the solubiUty 

 curve below 100° terminate into the t-axis, as indicated in tig. (1 

 It is obvious, that this is not compatible with the theory gi\eu above, 

 the prolonging of the solubility curve as far as the /-axis is certainly 

 wrong. Most probably the same phenomenon appears with SO^ and 

 KJ as Avith ether and anthrachinon ; the diagram may be somewdiat 

 different, the type, ho\vever, will be the same '). Hence it is not 

 improbable, that on prolonging the solubility' curve up to higher tem- 

 peratures we should again observe an iiu-rease of the solubility, so 

 that the direction up to the tirst critical temperature of llie saturated 

 solution will be somewhat like that indicated in fig. 7.
