corresponds to the central part of the milky way, and the last, 

 the region contained between the north pole and the galactic 

 latitude + 70°. In the following table, the first column represents 

 the galactic zones numbering from the south pole ; the second 

 shows the number of Algols contained in the zone ; the third, 

 relative area of each zone. The fourth column represents the mean 

 density of distribution of the Algols in each zone and the last 

 indicates the densities of stars in these zones, resulted from 

 Bonner Durchmusterung and investigated by Seeliger. 



TABLE IV. 



Looking over this table, we can easily see that the Algols 

 are mostly crowding themselves in the three successive zones 

 IV, V and VI ; evidently the zone V is the central part of the 

 milky way and the other tw^o are consecutive ones to the middle 

 zone. Possibly they are parts of the milky way itself: thus, we
