gSs Dr. Herschel's Account of the Changes 
Near 37 Aquilce. I, 13.* 
The position, Oct. 6, 1782, by a mean of two measures, was 
37 0 1 f north -preceding ; and, Oct. 2, 1802, it was 44 0 45'. The 
change is 7 0 30', in 19 years and 361 days; and may be owing 
to a parallactic motion. 
« Ur see minoris. IV, 1. 
There has been a small alteration in the relative situation of 
the pole star ; but, when we consider that this double star is of 
the fourth class, we cannot expect that any great change in the 
angle of position should have taken place, in the course of 20 
years. The position, Dec. 19, 178 1, was 66 0 42' south-preceding ; 
and, June 17, 1782, it was 67° 23'. A mean of both measures, 
is 67° 3'. March 4, 1802, the position was 6i° 43'; which 
gives a difference of 5 0 20', in 19 years and 350 days. A paral- 
lactic motion of the large star, which, considering the great 
difference of size between the two, may well be admitted. Will 
account for the angular change ; especially as the distance of 
the two stars exceeds the limits which probability points out for 
connected stars, when the large one is of the third magnitude. 
North-preceding FI. 62 Aquilce. I, 93. 
The position, Sept. 12, 1783, was 19 0 9' north -preceding ; 
and, Oct. 2, 1802, it was 13 0 21'. The change is tf 48', in 19 
years and 20 days. A parallactic motion of the largest of the 
two stars, would have occasioned a contrary apparent motion of 
the small one. 
* The place of this star is now given in Bode’s Catalogue, where it is 136 Aquilae.
