motion makes an angle of between 0° and 90° with the paralhxctic 

 motion; n^ similarly represents the nunihcr between 90° and J 80° 

 etc. If there were biil one stream, the (juantilies (■> wonld lie zero 

 for the whole of the skj'. 



The results obtained are shown in the following table. For the 

 sake of comparison I add, in the last colnnin but one, the value 

 0. computed from Ei)DiN(iT0N's numbers foi' the whole of the stars. 

 In the last column have been given the values of S as computed 

 from the numbers yielded by his theory. The tact that the accidental 

 deviations of column Oy. exceed those of the next one, will cause no 

 surprise, if we remember that for the former we had to confine 

 ourselves to a small |)art — the least reliable |)art — of (he materials 

 that served for the latter. Moreover we neglected the corrections 

 due to the deviations from a plane of the several regions. The region 

 of the Pole was left out, simply in oi-der somewhat to abbreviate 

 the work.
