According to a measure of Sir William Herschel in 1783, 
the position was np ; but in an observation of October 13, 
1782, we find Position a few degrees sp ; and in a sweep, 
Feb. 22, 1789, it is called “ almost directly preceding 
Distance in 1783, above 3 diameters of L. This star there- 
fore has undergone no change in either respect.

The difference between our position and that observed by 
M. Struve is enormous. To set the question between us at 
rest, the following additional measures were taken :

The position wire being set to + 7 0 ahd to — 7 0 , both ob- 
servers declared the angles to be intolerably erroneous, and 
about equally so either way. The star was about 3 hours 
from the meridian. This renders the measures of distance 
liable to some suspicion, and of course the others must be 
preferred, or at least be allowed double weight. This done, 
our mean result will stand as follows .* 
Position o°.f sp ; Distance 6".384 ; Epoch 1822.89.
