north polar distances of the principal fixed stars. 73 
The mean of these gives the latitude of Greenwich 
51 0 28' 39" ,5, or one-tenth of a second less than what Mr. 
Bessel found from his admirable investigations on Dr. 
Bradley's observations. He strongly contends for the ex- 
actness of 51 0 28' 39* ,6, which is o ",6 more than that recently 
assumed by Mr. Pond. 
(IV. ) Two stars in which Mr. Pond finds a great southern 
motion are 7 and x Pegasi. 
These two stars were observed by General Lambton, at 
his station of Dodagoontah, in the Mysore, at the same time 
that x Serpentis was also observed.* For « Serpentis, Mr. 
Pond finds none, or a very small, southern motion. 
We have hence an opportunity of comparing the relative 
changes of N. Polar distance of these stars and 2 Serpentis. 
An examination of the observations in the Asiatic Trans- 
actions will show, that for stars so near the zenith, much 
reliance may be had on the results of the observations. •'f-

t. It may b e said, that the observations made at Dodagoontah were not exact, 
judging by the irregularities exhibited by the latitude found by different stars. 
But these were owing to the errors of the catalogue of declination which General 
Lambton possessed. If the zenith distances be reduced, and applied to either of 
the Dublin Catalogues of N. Polar Distances, the latitudes by each star will be 
found to agree.
