VIII. A Catalogue of North Polar Distances of some of the prin^ 

 dp al fixed Stars, By John Pond, Esq. Astronomer Royal, 

 KR,S. 



Read December 17, 1812. 



1 HE catalogue which I have the honour of transmitting to 

 the Society, is the result of a great number of observations 

 made with the new Mural Circle, from the month of June last 

 to the present time. 



I hope at no very distant period to add considerably to its 

 precision ; but I trust that in its present state, it will not be 

 thought unacceptable to astronomers, as from the experience 

 I have now obtained of the instrument, I may safely pro- 

 nounce that it far exceeds in accuracy any thing yet known in 

 the history of practical astronomy. 



In the fourth column I have annexed the degree of uncer- 

 tainty, or maximum of error, to which I conceive the results 

 are hable. These numbers not being derived from any strict 

 mathematical process, must only be considered as indicating 

 the opinion I have formed on the subject. When the obser- 

 vations themselves are laid before the Society, I shall have an 

 opportunity of stating at length on what grounds this opinion 

 was formed.
