23 
On the night of the 2nd of October instant, while on a 
visit with my friend Mr. B. D. Naylor, F.R.A.S., at Bowdon, 
Cheshire, I turned his newly-mounted achromatic equatorial 
of 6 - 2 inches aperture, by Cooke and Sons, of York, on 1773, 
and observed three small stars near it which I took to be the 
objects I had laid down in my diagram of June 13, 186 1 ; but 
it afterwards occurred to me that the star c was not in the 
position shown in the diagram, and therefore on the night of 
the (ith instant, I directed Mr. Worthington’s 13-inch re- 
Hector upon 1773, when I at once saw that the star I had 
takAi to be c was in reality a new object, all the three stars 
seen on the 13th June, 1861, being in the positions shown 
in the diagram, though, strangely enough, c was about half 
a mag. less bright than I had estimated it to be at the time 
the diagram was made. The magnitude of the new star d 
was estimated to be 13-3. Using the 13-inch reflector again 
on the night of the 7th instant, careful estimations gave the 
magnitude of the four small stars a=13'2, 5=13T, c=14‘l, 
d- 13-3. 
The sky, for a short time before midnight on the 9th 
instant, was unusually clear to the west, and the three com- 
panions a, b, and d, were seen with the 5-inch achromatic, 
and their magnitudes, determined photometrically, were found 
to be, <z= 13*1, 5=12 8, c7=13 - 2. 
The relative positions of 1773 and its companion stars are 
shown in the annexed diagram. The distance of the new 
star d from 1773 is about 48/' and its angle of position 
about 315°.
