The longitude of Natchez is ftated in the 4th volume of the Tranfactions of the American Philofophical Society, page 451, at 16° 15′ 461 weft from Philadelphia, or 91° 29' 16" which is equal to 6h 5' 57" weft from Greenwich.-That determination includes all the foregoing obfervations previous to the 10th of January, except the immerfion, and emerfion of the 3d fatellite* on the 4th of that month, which from the imperfection of the theory were omitted.

* I have lately been furnished by Jofe Joaquin de Ferrer, an ingenious Spanish gentleman, with a number of valuable aftronomical obfervations, which he has made at different places on this continent: among them there are three on the eclipfes of Jupiter's fatellites made at la Guaira, which correspond with an equal number of mine made at Natchez.-They are the following:

Apparent Time.

The telescopes ufed by Mr. de Ferrer and myfelf were both acromatic, and nearly of the fame magnifying power, (that is about 120), the difference of the meridians will therefore require no correction on account of the difference of the inftruments, and may be fafely taken as above ftated: by which it appears that the town of Natchez, is 1h 38' 7".3 or 24° 31′ 49′′ weft of la Guaira.-The latitude of la Guaira as determined by Mr. de Ferrer is 10° 36′ 40′′ N.
