53 o Mr. Pond on certain changes which appear to have taken place 
of this motion appears to be such, that the stars are now 
mostly found a considerable quantity to the southward of 
their computed or predicted places. With respect to the 
laws by which these motions are governed, the observations 
in question are not sufficiently exact to throw any light 
upon them. 
Upon this very difficult point we must, I am inclined to 
think, rely chiefly, if not entirely, on the Greenwich obser- 
vations ; and as I have already fully discussed this question in 
my former Paper, I am unwilling, particularly at this advanced 
period of the season, to trespass any longer on the attention 
of the Royal Society.
