"Sir W. Hooker began collecting a Fern Herbarium in 1811. For this study this enthusiastic and illustrious botanist had all his life extraordinary advantages. The positions he occupied-first as Professor of Botany at Glasgow, and then as Director of the Kew Gardens-were made the most of, not merely by amiability of character which made his pupils and friends willing assistants, but at Kew he possessed the finest herbarium of ferns, and, thanks to Mr John Smith, the best collection of ferns in cultivation in the world. The names of travellers and botanists to whom he acknowledges obligations fill a page and a half of his preface. When Sir W. Hooker died, his son, Dr. Hooker, requested Mr. J. G. Baker to carry it out, possessing as he did full access to the specimens, and being supplied with Sir William's notes and annotations. The result is the publication of such a work as the author designed-a vade mecum for the students, cultivators, and collectors of ferns."-Athenæum. Ferns, British and Foreign.
