STUDIES O^ THE VARIABLES OF THE ALGOL-TYPE.

can safely conclude that the tendency of the crowding of the 

 Algols toAvard the milky way is pretty remarkable. Besides this, 

 we see that the corresponding zones both in the southern and 

 northern hemisphere show the different densities of distribution 

 and this fact tends to assert that the southern hemisphere have 

 a scantier number of Algols than the other hemisphere. 



But assuming that in both hemisphere the density is uniform 

 and the apparent phenomenon is only the result from the cause 

 of the southern sky unexplored by astronomers as if in the 

 northern, we shall take the mean density of the two corresponding 

 zones in the both hemispheres. The result is in the following 

 small table. 



TABLE V. 



The last column, as the ordinate, and the middle of the 

 zone, as the abscissa, represents a curve showing a slight curva- 

 ture, but the ratios are nearly in geometrical progression : the 

 actual quotients of these values, the preceding divided by the 

 following are 1.82, 1.96 and 2.00. Thus, it may be possible to 

 take these as a constant ratio 1.93. As we have such a simple
