324 Mr. Herschel’s and Mr. South’s observations of the apparent 
No. CCLXXXVII. continued. 
In Struve's Catalogue this is set down as III. 109, but 
there is great room to doubt their identity. 1st, the place of 
III. 109, as deduced from that of 19 Aquilas by the descrip- 
tion in the Catalogue, differs io' in R. A. and as much in de- 
clination from that of the star here measured. 2dly, neither 
the positions nor distances agree, the measures of III. 109 
being 22 0 6' np, distance 10". 22. If after all however it should 
really be the star, it must haye undergone a very great change 
in angle, and a considerable one in distance.
