The values tlius calculated for a are recorded in the table on 

 p. 754. With these the values calculated tVou) the critical quantities : 



,-r-A~) (9) 



have been compared. N = 6,08 X 10— ^3 (Sommerfkld). 



Thej are represented by o' and recorded in the last column of 

 the table. It appears that equation (8) gives values that are in perfect 

 concordance with those of equation (9) as far as order of magnitude 

 is concerned. It is noteworthy that the values for o' differ little 

 inter se, those for o presenting much greater differences between 

 each other. The alcohols show again great deviations.
