The Times of the Eclipses contained in this Table, are adapted to the Meridian of the Royal Observatory at Greenwich, and afford an excellent Method to discover the Lon. gitude, or Difference of Meridians, between that and other Place; which I shall illustrate by an EXAMPLE:

any

Suppose on the 28th Day of December of this Year, the Time of the Emerfion of jupiter's first Satellite be observed (by a Telescope) in an unknown Meridian, to happen at 14 b. 5 min. 22 sec. at night; I find by the Table, that the Time of this Emersion will happen at the British Observatory, at 12 h. 17 min. 2 sec, the same day: The Difference of the Times is 1 hour 43 min. 20 sec. which being converted into Degrees and Mioutes of the Equator, will make 27 deg. 5 min. the Longitude of the Place of Observation, to the East, because the Time is more than that at the British Observatory.
