1 18 Mr. Herschel’s and Mr. South's observations of the apparent 
24 v Cancri continued. 
Mr. Struve has determined the difference of declinations 
of the two stars composing this remarkable double star. His 
measure, reported in Zach’s Correspondence Astron. viii. p. 
370, was performed with a new wire micrometer by Frau- 
enhofer, and gave for the result 4" 85. If we calculate the 
difference of declinations from our angle and distance given 
above, we find 4". 78 for its amount, differing only o r, .oy 
from Struve’s.
