STUDIES ON THE VARIABLES OF THE ALGOL-TYPE. 4o 



ther this relation can be considered as one which has really a 

 physical meaning or is simply illusory, needs further investigation. 

 Next, let us consider the distribution of the ratio. The 

 ratios are known in 74 cases among 93 Algols and these are 

 contained among the limits 1.6 and 28.7. Classifying these into 

 several parts, we have the following results :
