APPENDIX III.
THE LITERATURE OF COMETS.
Cometary Astronomy, being only a branch of general Astronomy, has naturally no great amount of special literature attaching to it; but readers of this volume who may desire to add to their knowledge of comets may like to know what works to consult, so I append the titles of the chief of those in circulation. They are arranged in the order of date of publication.
