7. The Charts of Star Density. 



In order to get a general view of the distribution of the stars to the eleventh 

 magnitude, I at last give the result of this discussion in the form of two charts in 

 sinusoidal projection. 



In the first the 1730 squares are drawn and the average density of each of 

 these is given. The second chart shows the condensation of stars. Through the 

 squares, having approximately the same star density, continuous lines have been 

 drawn and the parts with greater density have been shaded. 



As can be seen, the Milky Way, of which the pole is marked with a star, is 

 very well defined, and it would no doubt be possible to determine the pole and 

 spherical radius of the Milky Way by a further discussion of the distribution of 

 the stars to the eleventh magnitude. 



In bringing this discussion to a conclusion I am glad to take the opportunity 

 of expressing my heartiest thanks to Professor C. V. L. Charlier for the great 

 interest he has always shown in my work, and for his kindness in placing the 

 Harvard Map at my disposal and giving me permission to work at the fine institu- 

 tion for theoretical astronomical research at Lund. 



The Royal Physiographical Society of Lund has received this paper into its 

 publications. For this favour I express my best thanks.
