16 AßT. 12. — H. HIKOEE : ON THE FUSION SURFACES OF THE 



of the crystals separated out was calculated, and the composition 

 of the solution was corrected accordingly. The maximum tem- 

 perature was constant for from 20 seconds to 2 minutes according 

 to the rate of cooling. 



The results of our determinations are given in the following 

 tables. 



TABLE 1. 



Fusion Curve No. 8. 

 Naphthalene-chloroLenzene. iSulid phase : nai)hthaleiit' . 



t is the fusion temperature in centigrade, 

 c is the weight of chlorobenzene added, 

 Jl is the degrees of supercooling + degrees of cooling during 



observation, 

 X is the quantity of the crystals separated out, calculated from 

 M and the heat capacity of the solution, the vessel, etc., 

 n is the weight of najihthalene in the solution at the moment 



of equilibrium, 

 Ca. is the molar fraction of naphthalene in the same sohition,
