ART. 19. N. ICIIINOIIE : 



we see that the Algols with a density comparable to that of the 

 sun are very rare and the majority of them are of very low 

 density. 



(e) MAXIMUM OR NORMAL BRIGHTNESSS. 



Let us, now, think about the distribution of the maximum 

 brightness and its related problem. Now arrange all the Algols 

 in the order of the maximum, and then, the distribution of the 

 maximum brightness will be found to be as follow^s ; 



TABLE XIV. 



In the above table, I omitted one for w^hich the exact 

 determination of the maximum, i.e., normal brightness is not yet 

 published. We see from this table that the number of Algols 

 increases with the maximum brightness till the tenth magnitude 

 and then the rate of increase is slackened. Possibly, this may be 

 due to the reason that our examination of the stars fainter than 

 the magnitude 10 is not so extended as that of the brighter stars.
