We will now give the observations that were made at the statioi, 

 whose positions were to be determined, following the order in which 

 they are enumerated in the beginning of this paper. 



VII. ASHTABULA, OHIO. 



Station — The centre of the Pubhc Square. 



Is^. Observations f 09' the Latitude {Approximate) 1858, Avg. 6th. 



The sky to the north was cloudy, and that to the south was still 

 more so, which prevented observations, as satisfactory as could be 

 wished, for the latitude. It was, however, obtained near enough for 

 computing the observations on East and West Stars for the tiine and 

 longitude, as follows, viz : — 



By 14 circum-meridian altitudes on y Cephei north, 

 combined with 2 observations (circum-meridian) 

 on Altair (x Aquilre,) and 4 on y Pegasi, both 

 south:— latitude - - - 41° 52' 04" N.
