SIXTY YEARS OF BRITISH MYCOLOGY. By M. C. COOKE, M.A., LL.D.. A.L.S., Sc. [Read October 16th, 1897.] THE current year has been remarkable for its varied retro- spects of the last six decades, and to these we propose to add another which will cover a field not yet traversed, and one of interest to a somewhat' limited section of Her Majesty's subjects. The study of Botany has advanced greatly in the present century, but in no division of that large subject has the advance been more remarkable than in that which embraces the Cryptogamia. Long after the list of Flowering-plants had assumed very respectable proportions, that of the Cryptogamia was small and somewhat confused. The study of these lower organisms was to a large extent excluded from general botany, and until very recent times the special study of Mosses, Lichens, Fungi, and Algae had never been attempted, save to a very limited extent. If we go back to our boyhood's days, although we have but very faint recollections of the reign of George IV., the reign of William IV. was not at all an active one for Biological Science. The instrument which was called a compound microscope in those days was only a toy, and wholly useless for botanical investigation. Ferns were recognized and placed at the end of the Flowering-plants, but for the rest Mosses only were beginning to be looked at with something of scientific interest. Previous to 1837 only one Handbook of Botany, which was in common use, can now be remembered, and that was Macgillivray's Edition of Withering's Arrangement, in one volume, but this was confined to the Flowering-plants, and those students who desired to gain some knowledge of the lower forms of vegetable life had to consult the complete Withering, in four volumes. Sowerby's English Botany did not come within the range of the ordinary student. This was the domestic era of the tinder box and rushlight, and before the first boxes of "Lucifers" astonished the natives at the cost of twopence half- penny each. There was real astonishment in rural districts over the first box introduced amongst them. Little flat matches drawn between folded sandpaper, producing an immediate flame. "Lucifers" they were called and Lucifer, under another cognomen, was supposed to be at the bottom of the mystery.
