Eclipses, Past and Future: With General Hints for Observing the Heavens

Excerpt from Eclipses, Past and Future: With General Hints for Observing the HeavensIt Iias been ascertained, that if the latitude of the moon be less than 1° 23' at the time of new moon, there will be an eclipse of the sun; and, if less than 51' 57 at the time of full moon, there will be an eclipse of the moon. There cannot be less than two eclipses in any year, or more than seven; and we are unable to mention any year in which this maximum number was attained. We suppose the reader to be acquainted, more or less, with the theory of eclipses. It is not our design to enter here into a description of the periodical equations and secular equations of the moon's motions, simply to give a brief description of eclipses on record in ancient and medieeval times, as such may prove of use to some for purposes of reference.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
