From infpefting thefe two table.?, it appears that the degree in 



latitude 13 34 44 is very nearly the fame in each: the mean being 

 60491 4 fathoms, which certainly m-uft be near the truth. We fhall 



therefore adopt it in future with the compreilion ■ for computing 



304 



the general tables of degrees for every latitude from the Equator to^ 

 the pole.

the Edinburgh Review, where we may call X, X, X, Sec, ..... Xj the 



degrees for latitudes L. L^i, L-^i, ^ + 3. &c. . . . . L 4- f?? — i ) 

 Now as the increment to each fucceeding degree will always be ns the 

 fine of twice the latitude ; or if m be any multiple of the fine of 

 twice the latitude, to be determined by certain data, the inciemenfe-
