While the Durchmusterung Catalogues determine A on the average 
for o from 11,5 to 13,5 (r= 200— 500 parsecs) the Selected Areas 
determine it between 13,5 and 16 (r == 500—1600 parsecs). In the 
main the values for 4 from the S.A. fit close to the values from 
the D.M. An exception is made by sector 165°; here the A curves 
intersect for o— 14,4, log A=9,5, but they show a different course: 
according to the S.A. the density is strongly, according to the D.M. 
it is hardly decreasing. In this sector the number of stars shows a 
discontinuity, as the strong increase for the magnitude 9—10 does 
not continue in the lower. magnitudes of the S.A. Presumably this 
is caused by the influence of a remote galactic stream, which must 
be studied in another way. 
PVE 
In order to find from these resulis the distribution of stardensity 
along the galactic section of the local system, values of g were 
deduced from our formulae, for which log A gets the values 0,0 
9,9 9,8 etc. In order to have no more irregularities in the resulting 
figure than are probably real, the results of the second computation 
were used for the sectors 75°, 135° and 315°. The values falling 
beyond the limits of the formula are placed in parentheses. 
(See table following page). 
These values have been used for the construction of the figure 
showing curves of equal density, decreasing with 0,1 for log A (at 
the curves the values of A itself are put down); where o is not 
determined by the data, but has been extrapolated, the curves are dotted. 
On the Southern hemisphere, where the density could not be 
found at greater distances than 500 parsecs, we perceive in sector 
315° (Scorpio) the condensation, mentioned above, at a distance 
100 —200 parsecs, where the density surpasses 1,25. For the rest 
the central mass with density 1 extends farthest in the direction 
/= 60°; at greater distances the maximum density lies in the sector 
45° (Cygnus), where a starstream seems to issue from the system.
