Burnham: Measures of Proper Motion Stars 
One of the prior measures must be rejected for obvious 
reasons. The other positions seem to show no change in twenty 
years. Engelhardt calls C 12.2 m.

Meridian positions of both stars will be found in the cata¬ 
logues of Bonn, Bruxelles, Cincinnati and Washington. They 
have very nearly the same proper motion. The direct measures

I have measured a faint star for the verification of this proper 
motion hereafter. 
The small star is DM (21 0
