By an azimuth of Polaris, observed with the theodolite and chrono- 

 meter, this night, and offsets measured next morning, from our station, 

 we get the following positions in Elyria, viz. — 



XXIII. CLEVELAND, OHIO. 



Station. — The point of intersection of the middle of Bank street, 

 with the north-western margin of Lake street.

The night was unfavourable for observation. The sky to the south 

 was entirely clouded, so that no star could be observed in that direc- 

 tion for the latitude. The only observations that could be obtained 

 for that purpose, were two altitudes of Polaris, north, which gave, 

 approximately, as follows, viz. —

Observations for the Time. 

 By 11 observations on a, Andromeda?, east (at 20h.

By 3 observations on a Ophiuchi, and 7 observations 



on oi Lyra3, both west (at 2lh. 29m.) 



Result — Chronometer No. 2557, fast of sidereal time

Clouds prevented observations on better time-stars in the west. 

 Both e Bootis and a. Corona? Borealis were carefully watched for, but 

 in vain ; also ^ Ilcrculis, at a later period of the night, but he also was 

 hidden from view. 



The great discrepancy between the N. Declination of « Andromedce, 

 and either u 0[)hiuchi, or cc Lyra), combined with the fact that the 

 latitude — which becomes a term in the equation for computing the 

 time, — was not closely determined, induces us to doubt if our chrono-
