to triple molecules. It has been found possible to represent 

 the fusion surface approximately by an equation based on this 

 hypothesis and derived from the fusion curves of naphthalene in 

 the binary systems, najdithalene-chlorobenzene and naphthalene- 

 phenol. 



5. The partition of plienol between chlorob'enzene and an 

 aqueous solution of common salt and sodium sulphate at three 

 different temperatures has been studied, the concentration of 

 phenol in chlorobenzene being in some cases very considerable. 



6. The results obtained support on the whole the hypothesis 

 that phenol is associated to triple molecules. 



The present study has been undertaken and prosecuted under 

 the kind guidance of Prof. Ikeda to whom my best thanks are due.
