NOTE I. 



THE Longitude of New York (page 297) deduced from 

 the solar eclipse, observed at Kindcrhook, and thence transfer- 

 red by chronometer, is to the west of Paris 5 h 05' 23"; and 

 by observations of the solar eclipse the 26th of June 1 805, at 

 Lancaster and New York, the result gave the longitude of New 

 York to the eastward of Lancaster (page 296) 9' 16" in time. 



h / 



Lancaster west of Paris, (page 297) = 5 14 41 



Hence New York west of Paris =(5h 14' 41"— 9' 16") . = 5 05 25 



By the mean result, New York 5 05 24 



Greenwich west of Paris. . . . ... 9 21 



New York west of Greenwich 4 56 03=74° 00' 45 



In page 158 74 07 45 



Correction of longitude to be applied to the places in page 158. . . —00 07 00 



Thus from the twelve longitudes on the coast, north of Cape 

 May, to New York, subtract 7' 00" of degree; as the longi- 

 tudes of those points were transferred by a chronometer from 

 the longitude of New York.
