All the obfen'ations for the longitude of Natchez after the 23d of March, 

 are entered as obferved by the clock, and will therefore require a correftion 

 to reduce them to mean folar time, which may readily be done from the 

 following ftatement of the errors of the clock, with its rate of going, at 

 different periods during the courfe of the obfervations.
