The distribution of the stars to the eleventh magnitude f> 



In some, fortunately rare, cases it has not been possible to distinguish the 

 actual images of the stars from defects in the plates. Such parts of the photographs 

 have either been neglected, or the counts have been made in the adjacent squares. 



Before commencing the counts, I have examined some plates in order to test 

 the method and to get into the habit of observing the images.

After having finished the counts, I have gone through the whole set of plates 

 once more and made ten counts on every plate. In this way 1 have ascertained that 

 no systematic error exists. 



The result of the counts is given in the following pages.
