68 Mr. Herschel’s and Mr. South's observations of the apparent 
57, m, Persei continued. 
The earlier measures, recorded in the Second Catalogue, 
are, 
Position 7T51 ' sp ; Distance 96". qp ; 1783.66 and 1783.27. 
This is an extraordinary change of distance, not less than 
thirteen or fourteen seconds, or one-seventh of the whole ; 
and is the more remarkable as the angle seems to have un- 
dergone no change. This star, therefore, merits careful ex- 
amination. The measure of 1783 is regularly entered and 
rightly cast up.

Sir W. Herschel makes the distance 70 ".62,5 (1st Cata- 
logue); 1780.8, agreeing almost precisely with ours. The 
angle is not given by him. 
(*) In Steuve’s Catalogue, this star is erroneously called VI. 88.
