No. 41. B.D.+ 43°,35i3. 0^400. (20^ G'^.g; = 43° 39'.) 



Mag. 7.5-8.5. 



The measures are in longitude. This is a binary with a period of 

 74.5 years (Burnham). The components are separated by o".3i. 

 The combined image, which is sensibly round, was bisected in the 

 measuring. Russell finds a hypothetical parallax of o".02i.
