For many years the Fossil Flora of the Yorkshire Coal Field has been engaging my attention, and among the species occurring in that district are many of considerable interest. This Coal Field supplied Artis with the specimens which he figured and described in his Antediluvian Phytology.
In 1888, at the Annual Meeting of the Yorkshire Naturalists' Union, held at Malton, a committee was formed for the investigation of the Fossil Flora of Yorkshire, and since that date four Reports have been prepared and published based upon specimens submitted to me for examination by private collectors, and from collections contained in public museums. These Reports only contain lists of the species found, and the localities and horizons from which the specimens were derived, with any occasional short notes that might have been thought necessary. All detailed descriptions or critical remarks were deferred, and the present paper is the first of what I hope may be several, dealing more in detail with the Fossil Flora of the Yorkshire Coal Field.
page 203 note * Antediluvian Phytology, illustrated by a collection of the Fossil Remains of Plants peculiar to the Coal Formations of Great Britain. By Edmund Tyrell Artis, F.S.A., F.G.S., London. In all the copies I have seen, the Introduction to the work is dated 1st September 1825, but the title-page bears the date 1838. This latter date is evidently that of a later issue, or second edition of the work, and may only be an alteration of the title-page of the copies subsequently issued. Each of the twenty-four plates contained in the volume bears the date of 1824. That the work was issued at least ten years before 1838 is evidenced by the fact that Brongniart quotes the book in his Prodrome d'une histoire des vegétaux fossiles, published in Paris in 1828. Probably, therefore, 1825 is the true date for the first issue of the Antediluvian Phytology.

Hemingway for my fine series of Yorkshire specimens of Dactylotheca plumosa, Artis, sp., from which largely the present paper has been written.

page 221 note † Note.—The other specimens of Sphenopteris crenata, L. and H. (pls. c.-ci.), came from the Whitehaven Coal Field, but I have hitherto been unable to visit this Coal Field, so can express no opinion as to their age.
