384 Dr. Herschel's Account of the Changes, See. 
a. Piscium. II, 12. 
The position of the stars, Oct. 19, 1781, was 67° 23' north- 
preceding; and, by a mean of three measures, taken Jan. 28 
and Feb. 4, 1802, it was 63° o'. This gives a change of 4 0 23', 
in 20 years and 105 days. The parallactic motion of « will 
account for the alteration, unless a proper motion should here- 
after lead to a different conclusion, which, from the insulated 
situation of this double star, is not improbable.

FI. 11 Monocerotis. II, 17. 
The position, Oct. 20, 1781, was 31 0 38' south-following; and, 
by a mean of two measures, taken Feb. 4, and March 4, 1802, 
it was 27 0 12'. The change, which is 4 0 26', in 20 years and 121 
days, may be accounted for by a parallactic motion. 
North-preceding y Aquilce. 1,91. 
The position, August 7, 1783, was 8° 1 8' north-preceding ; and. 
Sept. 20, 1802, it was 12 0 23'. This gives a change of 4 0 5', in 19 
years and 44 days ; and may be accounted for upon the principles 
of parallax. 
e Geminorum. Ill, 47. 
The position, Oct. 2, 1782, was 89° 34' south-foliowing ; and, 
April 6, 1802, it was 86° 6' south-preceding; which gives a change 
of 4 0 o', in 19 years and 186 days. This cannot be ascribed to 
parallactic motion. 
FI. 32 Eridani. II, 3 6. 
The position, Oct. 22,’ 1781, was 73 0 23' north-preceding; 
and, Feb. 6 , 1804, it was 77 0 19'. The change is 3 0 36', in 22 
years and 107 days. It cannot be owing to a parallactic motion, 
which would have produced a different effect.
