and positions of 4f5S double and triple stars, &c. 237 



No. DCCXXIV. continued.

 Distance r= 5".374 | 5 Obs. 



Diff! = o^ss's } Excessively difficult. 



This star is also double of the 5th class. By directing the eye to another part 

 of the field, a star of the 15th or 20th magnitude may be perceived almost directly 

 preceding. No measures of it however can be obtained with this instrument ; yet 

 the night is favourable, and the observations are made on the meridian. 



Mean Result. 

 Position 6° 34f sp; Distance 5"- 122; Epoch 1825.63.

Mean Result. 

 Position 60° 49' nf(is Obs.) ; Distance 38". 745 ( 15 Obs.) ; 



Epoch 1825.22. 



The position in 1783 was 57* 3* nf, differing only 3<* 46' 

 from the present angle. There is an apparent increase of 

 distance to the amount of + 3". 73 since that epoch ; but this 

 is very precarious. (H )
