 due to the Nubeculae) is ahnost at right angles to the direction of 

 the great agglomeration of stars in Cjgnus (comp. (able IX, 30° to 

 45° north). If, as it has been argued in Aj:}. J. XII, 2 — comp. 

 Versl. K. A. v. W. 1897/98 — the agglomeration of stars in the 

 direction of Cjgnus forms the center of the mainly spirally arranged 

 galactic system, of which the unequally dense ^\indings surround 

 the sun, this result (if we also accept the other suppositions mentioned 

 in this paper) was to be expected.

star-windings in the galactic plane — which, as regards the type 

 of condensation of the matter, has been identified with the "extra- 

 galatic" regions (I'ich in nebulae proper) extending on either side 

 of the galactic plane — will extend furthest out in the direction 

 AB, at right angles to a line passing through the sun and the central 

 condensation of the system. This will especially be (he case at 90 degs. 

 from the central condensation or rather a little nearer to it in the 

 direction « where the great gap between the windings (Perseus
