As a writer of text-books Henfrey was very prolific. First came his _Outlines of Botany_, 1847, followed by the _Rudiments of Botany_. Much more ambitious was his _Elementary Course of Botany_ which became a standard text-book running through numerous editions after his death, under the editorship of the late Dr M. T. Masters. To these must be added, in conjunction with Griffith[106], the _Micrographic Dictionary_, a substantial volume dealing in innumerable special and general articles with the microscopic study of plants and animals. This work was no mere compilation, but embodied in its pages is a very large amount of independent observation. The illustrations covering nearly fifty plates were by Tuffen West, and reached a high degree of excellence. A well known botanist, a contributor to the present volume, has more than once assured me that it was to the _Micrographic Dictionary_ that he owed his salvation! Should anyone desire to get a vivid and accurate picture of the precise state of Botany in this country at the middle of the last century, he cannot do better than turn over the pages of _The Botanical Gazette_, a monthly journal of the progress of British botany, founded and conducted by Henfrey. It was about the size of our own _New Phytologist_, with which it had not a little in common. In one respect it differed; unlike the _New Phytologist_ the _Gazette_ was financially a failure and after carrying it on at his own expense for three years (1849-1851) Henfrey had to relinquish the undertaking. A perusal of its contents clearly shows that its editor regarded his journal as one of the instruments of diffusing the New Botany. Having to rely largely for his subscribers upon the amateur collector he points out in the prefatory note that a feature will be made not only of home botany but also of contributions or abstracts from abroad dealing with floras which have much in common with our own. For the benefit of those whose collections had reached considerable dimensions, and for whom the lack of new plants might connote a waning stimulus, he held out the further inducement of papers on the general anatomy of familiar plants, of which an excellent example by Thilo Irmisch on the stolons of Epilobium was included in the first number.
