Price £1. 28. 6d. plain; £1. 88. coloured by hand. EVERY KNOWN FER SYNOPSIS FILICUM; including OSMUNDACEÆ, SCHIZEACEÆ, MARATTIACEE,

and OPHIOGLOSSACEÆ, Accompanied by Figures representing the essential characteristics of each Genus. By the late Sir W. J. HOOKER, K.H., and JOHN GILBERT BAKER, F.L.S., Assistant

Curator of the Kew Gardens. This is the cheapest and most complete book which describes all the Ferns throughout the world. So full and clear are its details that anybody who will take the trouble to master a few botanical terms can with certainty name any fern he may meet with in any part of the world, whether growing wild or under cultivation in garden or hothouse.

“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 be occupied first 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 bis 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." -Athenaeum.

" Before the appearance of Mr. Smith's book scarcely more than three or four kinds were freely accepted by prudent cooks. We have now before us the list of esculent mushrooms recommended, nay, warranted by Mr. Smith, of all of which he and his friends have freely partaken, with the most satisfactory results, and many of which are far more delicious in flavour and toothsome in substance than the meadow and horse mushrooms, generally known as the mushrooms of commerce."--Pall Mall Gazette.

There is a thoroughness about Mr. Cooke's writings which always makes his communications welcome. He is not content to gather information from cyclopædias, classify and adapt, and then give a new form to the thoughts of others. On the contrary, he strikes out a new course of study, and after a laborious course of analysis, produces an entirely original work, one on which nothing of the kind had been before attempted." - Wesleyan Times.
