 of BC. Position 17** 30' w/(28 Obs.); Epoch 1825.51. 

 The observations of A C when seen only as a double star, are 

 not included in the mean result. 

 Not the slightest alteration appears to have taken place in 

 the relative position or distance of the close stars. The 

 angle measured by Sir W. Herschel in 1782 was 82° 2' 5/, 

 differing only 6' from the present ; while the interval, esti- 

 mated at ^ or -J of a diameter, would correspond to a distance 

 of about if. (H.)
