Skewness : 



Values from radial veloci 

 ties (Gyllenberg) 

 stars of magn. <fT 4.9. 



— 0.134 + 0.113 

 + 0.007 ± 0.111 

 + 0.008 ± 0.138 



Values from proper mo- 

 tions (Wicksell) 

 stars of magn. <ï 5.9. 



— 0.084 ± 0.017 

 + 0.039 ± 0.078 

 -f 0.131 ± 0.038 



E -f 0.004 + 0.036 — 0.141 ± 0.007 



Excess : H -f 0.109 ± 0.035 — 0.028 + 0.033 



Z 4- 0.116 + 0.044 + 0.273 ± 0.08B 



Except the in case of the excess in the S components and perhaps also in the H 

 components these values are of the same order of magnitude as ours for stars of 

 magn. < 4.9. As pointed out by Wicksell another choice of the numerical 

 value of the fundamental stellar constant q\ entering the density and luminosity func- 

 tions, on which his results depend, would make his values grow considerably in 

 magnitude and make them still less in consistence with the above radial velocity 

 results. 



In the figures 16 — IS I have made a graphical representation of the fre- 

 quency function of the velocities when regard is taken to the higher characteristics. 

 The dotted line denotes the normal curve. The small circles represent the observa- 

 tions and the drawn line is the theoretical curve.
