Where dashed tenus refer to a second point of the isothermal 

 under question. We have to solve 7ii and 71/ from the two 

 equations by inspection, but there is the condition that no > 

 that is a > 2 ?ii. We tried to apply the equations to an iso- 

 thermal curve in order to obtain Ui and n/ , but found that they 

 were impossible under condition 710 > 0. Hence it is clear that 

 the deviation can not be explained in that way. In the next 

 place suppose there exist quadleple molecules whose number is 

 ?i4, then we have the analogous simultaneous equations for ?Zi, ??,/, 

 and they were found not to be impossible under the condition 

 71^ > 0. But as the simultaneous equations contain the fourth 

 power of 7^l the experimental error is extraordinarily magnified 

 and no conclusive result can be arrived at. 



II. Partition Coefficient of Phenol between Water 

 and Chlorobenzene. 



The theory of the constant partition coefficient has been 

 developed by Nernst from the theory of the dilute solution, 

 and since that time it has been customary to apply this law 

 only to the study of dilute solutions. But the field of its 

 legitimate application is much wider. The only condition to be 

 fulfilled is the sufficient immiscibility of the two solvents, and
