The small star is so excessively indistinct, that the measures, especially those of 

 distance, must only be regarded as approximations-. 



The star here observed is indisputably 38 Ophiuchi. I had 

 re-measured 36 Ophiuchi for it in Blackman-street twice 

 during the summer of last year ; not having found any other 

 double star in the neighbourhood. On comparing however 

 my observations with Sir W. Herschel's, it was evident thai 

 we had not measured the same star ; and by close attention 

 the small star of 38 Ophiuchi was perceived. My first attempts 

 to determine the distance proving unsuccessful, cautious esti- 

 mation regarded it as 5 or 6 seconds : the night however 

 having somewhat improved, the above observations of it were
