TABLE in. 



Possibly, in the future, ^ve may discover 40 and more 

 Algols in the southern heavens than we have the possibilities 

 of the new discoveries in the northern sky, if we have reason to 

 believe in tlie uniform distribution of the Algols tlirougli the 

 entire sky. 



But if we consider the distribution according to the present 

 statistics as real, the number is the maximum in the region 

 contained between the ascending node in the constellation Aquila 

 and the middle of Cygnus and in the region contained between 

 the descending node in Monoceros and the middle of the con- 

 stellation Argo, the number of Algols is minimum, here it being 

 only one. A graphical representation of Table III may clearly 

 give the general tendency of the distribution of these known stars. 



Let us now examine the law of agglomeration of the Algols 

 with respect to the galactic latitude. Suppose the whole celestial 

 sphere is divided into the nine zones, each zone being 20 degrees 

 in its width : thus, the first zone extends from the south pole 

 of the galaxy to the circle of the galactic latitude -70°, the next 

 from -70° to -50° and so on. Then, of course, the fifth zone
