From all the longitudes on the Ohio and on the Mississippi 

 (page 159) which are expressed in time, subtract 14" of time, 

 or 3' 30" of a degree, also from the longitudes from the Bar 

 of Santander, to the point on the coast, subtract 3' 30". The 

 whole having been transferred from Natchez by chronometers; 

 from the longitude of which last place, a like deduction ox 

 correction is made, as determined from the last solar eclipse.

In page 301, from a communication by Mr. Simeon Dt 

 Witt, it appears that the total darkness was instantaneous, or, 

 continued but a moment, 



In latitude 43° 22' andlongitude east of New York. . . 00° 45' 00" 



In latitude 41 30 do. west of ditto. ... CO 14 00 



These last observations are the most important to determine 

 the latitude of the moon, and the difference of the semidiame- 

 tcrs. It may also be noted that though the total darkness should 

 not have been instantaneous, but even of a quarter of a minute's 

 continuance, yet this influence on the result woidd have been 

 insensible, or not amounting to a single second. 



The calculation being applied, it results, that the moment of 

 total darkness was, — 



In latitude 43° 22' and longitude 45' east of New York at ll h 14' 07"' mean time 

 In latitude 41 30 longitude 14 west of do. 11 07 17 ditto.
