124 ^^'' Pond's Observation of the Winter Solstice, ^c, 



rate paper, I shall not add any thing farther on the subject, 

 excepting a recommendation to astronomers, to deduce their 

 refractions from circumpolar stars altogether, and then exa- 

 mine the solstices with those refractions, and by no means to 

 make the coincidence of the solstices a required proof of their 

 accuracy. 



Note, In the annexed computation the reduction*to the sol- 

 stice is computed from the observed right ascension of the sun, 

 by this means the errors of the tables being avoided, obser- 

 vations at a considerable distance (even some weeks from 

 the solstice) may be employed, particularly in the winter 

 season, when the uncertainty from refraction is greater than 

 the error which may be probably introduced into this part of 

 the calculation.
