THE ESSEX FIELD CLUB.—REPORTS OF MEETINGS. 161 Mr. Massee named and arranged the specimens. Fungi were less plentiful in individuals than on some previous occasions, but the species noted were some- what numerous, 265 in number, and included several new to the Forest list, and some very rarely met with. Mr. Massee reported that "perhaps the beautiful specimens of Hydnum imbricatum L. and Polyporus rufescens Berk, were of the greatest interest. Both are rare everywhere in England, and the latter is very seldom met with outside the forest. Among the Agarics the genus Tricholoma was represented by no fewer than ten species, perhaps a record number for the Forest. Of these Tricholoma oreinum. Fr., T. boreale, Fr,, and T. subpulverulentum, Pers., are new Forest records, I believe." " Among Micro-Fungi determined afterwards were Helicomyces roseus, Link, and Tetrasporia aristata, B. and Br, ; these are also new to the Forest.'' Demonstrations on the many fine specimens in the room were freely given during the afternoon by the many skilled botanists present. Tea was taken about 5.30, and on returning to the exhibition room, Mr. Massee gave an Address on some recent researches on "Diseases of Fruits," mainly those caused by various minute funguses. He demonstrated the very interesting life-histories of several of these fungi, and discoursed of the best methods to be adopted in resisting their attacks. The address was illustrated by a set of very beautiful original colour drawings from Mr. Massee's own pencil. The President, Mr. Miller Christy, F.L.S., proposed a vote of thanks to Mr. Massee for his great services during the day, and for the exposition he had just given of a subject of the greatest value to gardeners and farmers in the county. The company separated about eight o'clock, after a most interesting and successful meeting. The forest had never looked better at any previous "Foray," and the excellent outcome of the forestal operations in former years was apparent in the vigour and luxuriance of the trees and undergrowth. THE 241st ORDINARY MEETING. Saturday, October 28th, 1905. The first meeting of the winter session was held ou this evening in the Physical Lecture Theatre of the Municipal Technical Institute, Stratford (by kind permission of the Education Committee, and the Principal, Mr. Hogg), at 6.30 p.m. The President, Mr. Miller Christy, F.L.S., occupied the chair.

Dalton, F.G.S., F.C.S., exhibited and presented a collection of specimens of Rocks and Minerals intended to fill vacancies in the type collection so instructively arranged by Mr. Reader in the gallery of the Museum.
