Preface to Second Edition. In the course of only a few years many new vegetable remedies are introduced, while others drop out of use entirely. It has been our endeavour to limit the drugs herein mentioned to those which are of commercial value and which may be regarded as obtainable; consequently several additions will be noted as well as omissions from the first edition. The notable alteration in this edition is the descriptions given of the distinctive characteristics of each drug, by which, it is hoped, the genuine article may be easily identified. Mr. E. M. Elolmes, F.L.S., perhaps the best-known authority in England on medicinal plants and drugs, has kindly undertaken to be responsible for this part of the work. Mr. Holmes has also revised the botanical names of all the drugs, supplied a glossary of botanical terms and a list of authorities,

IV. PREFACE. and to the latter is added a characteristically interesting explanatory note on this particular subject. It has been found necessary to omit from this edition the Indexes of Books and of Medical Receipts, but as these were compilations, and the information otherwise obtainable, the usefulness of the work is not impaired. On the other hand the additional literary matter added has not only increased the number of pages, but will, it is hoped, enhance the value of the work to a very great extent. In its present form Potter’s Cyclopaedia should prove useful to every person who handles drugs or herbs in either a small or large degree. R. C. W.
