These corrected longitudes were not yet available for the maps produced by Nicolas Sanson of Abbeville, since 1627.
WEST VIRGINIA, the north-westernmost of the so-called Southern states of the United States of America, lying between latitudes 37° 10' and 40° 40' N., and longitudes 77° 40' and 82° 40' W.
This, of course, varies in different longitudes, while a further difficulty occurred in the attempt to fix the correct time of Easter by means of cycles of years, when the changes of the sun and moon more or less exactly repeat themselves.
NORTH CAROLINA, a South Atlantic state of the United States of America, situated between latitudes 33° 5 1 ' 37" (the southernmost point of the southern boundary-35° is the northernmost) and about 3 6 ° 34' 2 5.5" N., and between longitudes 75° 27' W.
Since 1890 further and more rigorous application of the telegraphic method of determining longitudes differentially with Greenwich has resulted in a slight correction (amounting to about 2" of arc) to the previous determination by the same method through Suez.
