OF A COUNTY HERBARIUM. 77 expert botanists should be formed, to whom all plants collected should be submitted, and on whom should fall the responsibility of selecting those plants suitable for the herbarium. This committee should also superintend the labelling, mounting, and arranging of specimens. Possibly some of our lady members may volunteer to assist in this department, in which their nimble fingers would give them an advantage. I must not omit to thank Mr. F. J. Hanbury for his kindness in showing me his large collection of plants, and in making some valuable suggestions, which I have utilized in this paper. In conclusion, in order to make my paper complete, I must say a few words upon the literature of this subject. To the tyro I cannot do better than recommend him to purchase "Bentham's Handbook of the British Flora" (Lovell, Reeve & Co.). This work distinctly treats our flora in the manner of the so-called "lumpers"—no small advantage to the beginner, who is apt to be puzzled by the too critical division of species, but who, when familiar with the easily-recognised variations in plant-life, will find less difficulty in mastering the more minute deviations. This work is provided with a most useful artificial key, by means of which the merest tyro should find little difficulty in naming most plants. A companion volume, containing a series of wood engravings, by Mr. W. H. Fitch and our member, Mr. Worthington G. Smith, of all the species described in Bentham, is published. It will be found of the greatest use to the tyro who, having made up his mind as to which description his plant best accords with, can refer to the plate of that species, and make sure that he has named it correctly. But he must beware of getting into the bad habit of depending upon pic- tures instead of descriptions and scientific characters for identification. Should he unhappily fall into that error he will never make a botanist. To the more advanced botanist I should recommend Babington's "Manual of British Botany" (John Van-Voorst), and the "Student's Flora," by Sir J. D. Hooker (Macmillan & Co.). Both of these works are really necessary, for each of them will be found to offer special advantages; for instance, while Babington's "Manual" is the work I should refer to in discriminating between those puzzling plants, the Rubi, Hooker's work gives the best account of the almost equally puzzling plants the Batrachian Ranunculi. Thus, the two books form valuable companion volumes. Another book which will be found most useful is Hayward's "Botanist's Pocket Book" (George
