122 FROM NEBULA TO NEBULA

 have:

That is to say, the drift of the sun will SEEM to anyone not 

 in possession of the key to be, not merely to right ascen- 

 sion 270, but also to declination + 33 13'. On a similar 

 line of reasoning, it can easily be seen that the vertices of 

 preferential motion of the stars should appear to be re- 

 spectively in K.A. 90, Dec. + 11 45', and R.A. 270, Dec. 

 11 45', proving that the so-called star streams are 

 nothing other than an optical illusion. Now compare 

 these results with those derived by others by the labori- 

 ous and conventional methods of empirical observation 

 and analysis. I quote from Doctor W. W. Campbell's 

 Stellar Motions (p. 147) : 



Below are solutions for the apex of the sun's motion and for 

 the vertices of the two star streams, by Kapteyn, Eddington, and 

 Dyson; and for the positions of the solar apex and of the vertices 

 of Schwarzschild's ellipsoid of preferential motion, by Schwarz- 

 schild, Beljawsky and Rudolph.

Before we can label these conclusions final, however, 

 we cannot neglect to take into account the optical effect 

 of the sinking of the ecliptic on the apparent position of 

 the stars. For it is obvious that, inasmuch as our descent 

 is wor/iward, those stars on or closest to this plane which 

 are nearest us in point of distance will appear as drifting 

 soi^/fcward, whereas those more distant and in the order 

 of their distances will seem to be traveling toward the
