A Catalogue of Recent Comets.

In the appendix to the Index to vols. xxx to lii of the Monthly Notices R. A. S. there is a very useful table compiled by A. C. D. Crommelin of Reference Letters, Year-numbers, Dates of Discovery, Perihelion Passages, and Periods (if any) of comets discovered between 1869 and 1894.

Several of the books on comets, mentioned under the head of "The Literature of Comets" in Appendix III, contain catalogues of comets, some of them very exhaustive, but unfortunately they do not for the most part come down very near to the present epoch.
