5 Summary of the preceding Tables. 



In the preceding pages is given tlie result of the counts of stars made on the 

 Earvard Map. In order to get a view of the distribution of the stars on the dif- 

 ferent negatives I put togetlier in a talkie the following quantities: 



The number of counted stars, S 



the average star density of the plate, M 



and the calculated total number of stars.
