of the principal Jixed Stars. 303 



There are several other stars much better adapted for this 

 investigation, even should their distance be supposed more 

 than double, such are Polaris, ri Ursae maj. « Cygni, /3 Urs. 

 min. and 7 Draconis; now in these I have not hitherto found 

 any sensible parallax ; occasional discordance has frequently 

 suggested some slight hopes, but these have always been dis- 

 appointed by continuing the observations. It is, however, 

 useless now to anticipate this subject farther. 



Those stars which are in the general Catalogue, but which 

 do not form part of the standard Catalogue, I presume to be 

 exact to the nearest second. 



I have not included any star in the standard Catalogue south 

 of the equator, on account of the uncertainty of refraction.
