The distribution of the stars to the eleventh magnitude 



85 



75 — 80 18 hourcircles i, e. 18 squares 

 80—85 12 » 12 » 



85—90 3 3 



The hemisphere 865 » 



the whole sphere 1730 » 



In this way I get 1730 squares of approximately the same area. Withiii each 

 of these squares he on an average about 3 values of the star density. I take the 

 mean of the values in the squares and consequently 1 get as a final result the 

 mean star density of 1730 squares uniformly distributed over the entire sky. 



The densities derived in this way are collected in the catalogue of star den- 

 sity given beneath. 



6. The total Number of Stars to the eleventh Magnitude. 



In Stellar Statistics I Prof. Charlip^e has divided the sphere into 48 squares 

 and discussed the number of stars in a series of these. In order to get the total 

 number of stars to the eleventh magnitude I calculate, by aid of the catalogue of 

 star density the number of stars in each of ihe 48 squares. The result is tabulated 



By adding the results from all the squares, I get the total number for the 

 ;vhole heaven, which is 



1 013 328.
