With these values of Cl and % we proceed to calculate x 

 for various temperatures of fusion employing the equation (7). 

 The values so calculated are compared with the experimental 

 data in the following table. 



TABLE 3. 



Fusion curve of naphthalene calculated 



In four cases, Nos. 10, 11, 12, and 13 the difference bet^veen 

 the experimental and the calculated values of x exceed 0.59^ ; 

 and as is to be seen from Table 1, it was in these cases that 

 the degree of supercooling had been excessively large. In all
