These latter characteristics are as we have before shown practically independent 

 of & 1 and its systematical variation. With their mean errors they give a general and 

 complete description of the distribution of the linear motions of the stars of a magnitude 

 brighter titan 6.0 as far as it is given by the proper motions and, as far as it is possi- 

 ble at present to determine the value of the constant q. 



30. We are now in a position to ascertain in how much onr results are in 

 consistence with the two-stream hypothesis 



In the following table we give the values of the characteristics as computed 

 from the figures cited from Eddington in § 25. In the second we point out what 

 becomes of the characteristics if we assume that the internal spread of motion is 

 different in the two streams. In the third column we give the evidence of our own 

 values.
