The great eclipse of 1842 marked the dawn of a golden age of physical research upon the Sun, and the conclusion of a half-century of significant research forms a fitting epoch for summarizing salient results in review. Advantage has been taken of this opportunity to present the attractive features of remote eclipses; and the connection of those in early, mediæval, and later centuries with contemporary history will, it is hoped, add new interest to astronomical events already widely celebrated. The abundant references have been critically verified in the libraries of Amherst College, of the American Academy of Arts and Sciences, Boston, of Harvard College Observatory, and in the Newberry Library, Chicago.<br><br>Necessarily the ample illustrations have been chosen from a wide field. Particular attention is called to the collection of coronas of the different eclipses. Especial care has been bestowed upon the chart of eclipse tracks in the future.
