In the following table, the results of computation are 

 arranged in the order of increasing period with the data needed 

 for the reduction. The first column is the number of the above 

 list and the second represents the name of star. The third is 

 the period and the next two columns represents the ratio between 

 the period and the duration of the eclipse, and its reciprocal. The 

 last column is devoted to the required density of the Algol- 

 systems. As the constant for the above formula is the same with 

 that of Kussell, the results must be coincident to each other for 

 17 stars when the material is also based on the same catalogue. 

 In fact, as I used different data for some of them, we cannot 

 avoid a little difference between them. At the same time, as 

 the results of 37 stars by Stein are given in the unit of solar 

 density, they wdll be comparable with mine, when a constant 

 factor 1.41 is multiplied. Actually, as the data for some stars 

 differ from his, the results will not be same even when that factor 

 is taken.
