96 NEW DOUBLE STARS AND MEASURES, 
they are out of the reach of northern observers, and, so far as I 
can learn from published lists, they are new ; but hereafter, when 
the work of several double star observers in the southern hemis- 
phere is published, it may be that some will be found in other lists. 
any of them are very close and otherwise interesting doubles; 
and there is every probability, seeing that h..overlooked them 
when in close proximity to stars that he observed, that some of 
them will prove to be binaries. 
Only a few of them have as yet been repeatedly measured, but 
of these several show signs of motion. One at 12h. 4m. 60° aI 
was found in April, 1873, and then the measured angle was 
212°35°, in May, 1880, it was 209-55°; at first the distance was 
4:33”, last year it was 3-87”, showing a change of 3° in angle an 
0-46” in distance. Another at 15h. 50m., and dec. 65° 37 im 
July 31, 1872, angle 134° 12, dist., 2-43”; on July 21, 1880, 
angle 131° 19’, distance 1-91”, again showing a change of 3° and 
0-52". Another very difficult pair at 10h. 45m., dee. 58° 38 
found in March, 1874, angle 256°, distance } a second, and im 
March, 1880, angle 258-81°, distance 1-15’; this one I have mer 
tioned in the paper on double stars last year, but place 1t here for 
completeness. : 
other star at 13° Om. 59-14°, found in April, 1880, gives some 
indication of increasing distance, which, when first measured, was 
0°33”, and when last seen was 0°70”.
