The list of comets has been taken from Carl’s _Repertorium der Cometen Astronomie_ (Munich, 1864). It begins with the comet discovered by Hevelius in 1672, and ends with that found by Donati on the 23rd of July, 1864; Gambart’s comets, already separately enumerated, have been excluded. To keep the conditions analogous to those of the small planets, all the comets to which Carl does not assign a discoverer, have been omitted; this includes such as were expected from previous calculations or perceived with the naked eye by the general population. All those that were discovered simultaneously by several observers, unknown to one another, have, however, been included, for it is not a question of priority, but of the psychological moment of the discovery. Three comets discovered in the months of February, May, and December, were found in the southern hemisphere; they must, therefore, with reference to season be registered as for August, November, and June, and have so been counted.
