Points of intersection (form. IJ) at dev, 2.60 and 9.19. 



The sums of the differences between the limits of the observed 

 points of intersection are, as given in Table IV, +48, — 70, -+22. 



If we also wish to compare these quantities with the result 

 of the theory, we have to integrate (6) between the limits deduced 

 from (11). For the limits « and zero we tind the frequency :
