Dear D^r Wallace

I have just read a new paper by Newcomb¹ in the "Astronomical Journal"² No. 525, and set down the net result or the chance of its being useful to you. If is this; If we could measure the parallaxes of all stars [2] with a sensible proper motion, the average value of their parallaxes³ would be about one one-fifteenth⁴ their average proper motion.

P.S. He considers further that the following two hypotheses may be provisionally adopted.

1. That of general equality in the scattering of the stars.

2. That of the absence of any systematic trend [3] in their movements.
