Refractions The above determination differs but 16".3 from the latitude of NewOrleans as ftated in the requifite tables, and which may have arisen from the obfervations being made in different parts of the city. Longitude of the city of New-Orleans, deduced from the eclipfes of 4's fatellites. From the 24th of January, till I left New-Orleans, I was engaged in decking, and rigging a fchooner, to tranfport our baggage, apparatus, and provifions along the coaft, and therefore unable to attend conftantly to the going of the clock, which was fet up in a place much expofed, and probably the cafe was by fome accident fhifted a small matter between the 6th, and 17th of February, from the pofition it had when fet up: This appears likely from the rate of the clock's going during that interval. An emerfion of the 1ft fatellite of 2 was obferved on the 14th of January at 6 10' 37" P. M.-the clock was then too flow mean time 10' 05", the obfervation was therefore made at 6h 20′ 42′′ mean time, from which deduct 9' 48" the equation of time, and the remainder 6h 10′ 54′′ will be the apparent time, which deducted from 12h 12' 19" the apparent time at Greenwich by the theory, the remainder 6h 1' 25" will be the difference of meridians. An emerfion of the 1ft fatellite of 4 was obferved on the 21st of January at 8h 2' 9" P. M. The clock at the time of obfervation was 14' 34" too flow mean time, the obfervation was of courfe made at 8h 16′ 43′′ mean time, from which deduct 12' 0" the equation of time, and the remainder 84' 43' will be the apparent time of the obfervation, which deducted from 14h 5' 43', the apparent time at Greenwich by the theory, the remainder 6h 1' oo" will be the difference of meridians.
