    Description
    Astronomical study of the head of Donati’s Comet observed through the 15-inch refracting telescope at the observatory of Harvard College.

    The author describes the comet on this day: “The nucleus...was unusually bright, and rounded on the side toward the sun. An increase of brilliancy in the nucleus was afterwards recognized as the precursor of a fresh eruption from its surface...There were three dark openings in the innermost envelope, between which it was intersected with bright rays. In Plate I the engraver has given an eminently successful representation of the comet as it appeared in the field of the great refractor.”

    Donati’s Comet was one of the brightest to be seen in the 19th century and was the first to be photographed (by G.P.Bond and others). It was discovered by the Italian astronomer Giovanni Battista Donati (1826-1873).

    Plate 1 from the monograph An account of Donati’s Comet of 1858, by George P. Bond (Cambridge, Mass., John Bartlett, 1858). ” Inscribed: “PLATE I. Drawn by G.P.Bond. Engraved by J.W.Watts. Comet of Donati Oct. 2nd 1858.”
