THE COMING OF AGE OF THE ESSEX FIELD CLUB. A RECORD OF LOCAL SCIENTIFIC WORK; 1880—1901. By RAPHAEL MELDOLA, F.R.S., V.P.C.S., F.R.A.S., F.I.C, V.P.R. PHOTOG. SOC, Professor of Chemistry in the Finsbury Technical College, City and Guilds of London Institute; Member of the Faculty of Science, University of London. President of the Club, 1880-1882 & 1901-1902. [Being the Presidential Address delivered at the 22nd Annual General Meeting of the Club on March 22nd, 1902.] " Our Society, in general terms, may be said to have for its scope the study of Nature in the field...... " In forming a Society such as the present Field Club our primary object is, of course, the furthering of Science—the annual addition of some- thing, however humble, to the general stock of human knowledge. In Epping Forest and the County of Essex we have a fine area to work in.........

I acceded to the wish of your Officers and Council that I should again take office as President in celebration of our coming of age, partly on the unsubstantial ground of sentiment and partly because I may claim to have taken an active interest in the welfare of the Club and to have kept in touch with its proceed- ings from the time of the foundation meeting on January 10th, 1880.
