180 THE ESSEX FIELD CLUB. The Club's library now comprises 5,505 bound volumes, no less than 96 having been bound during the year ; new book cases are being obtained to accommodate the increasing number of books. The growth of the Pictorial Survey collection is such that additional cabinets and albums to contain the photographs and prints have become a necessity, and it is gratifying to learn that the West Ham Corporation has generously undertaken the provision of these. In connection with the Survey, also, it is contemplated to acquire a special type of photo- graphic enlarging apparatus, which will, it is hoped, inspire our members to loan their small-sized snapshot negatives and films in order that en- largements made be taken therefrom for the Survey collection. At the Forest Museum, Queen Elizabeth's Lodge, changes are im- pending which have given your officers much correspondence with the officials of the City of London Corporation, and have caused some anxiety as to the future care of the Club's exhibits in that Museum. The matter is still sub judice and further developments are anticipated in the near future. The Essex Naturalist has appeared at regular six monthly intervals. In conclusion, your Council again commends to all the members the urgent desirability of enlisting new recruits to increase the membership of the Club. DIDYMIUM LISTERI MASSEE IN EPPING FOREST. We regret that, by a compositor's error after the proofs had been corrected, a line of text in the last part of this Journal describing the newly-recorded Essex myxomycete, Didymium Listeri Massee, was dis- placed from its context (p. 109) and so rendered the sentence unintelligible. It should read as follows :— " Our rarest species was a specimen of Didymium Listeri Massee, a new record for the county. It was found by Mr. Ross on a dead holly leaf, and consisted of a flat snow-white plasmodiocarp, about 5 mm. across," etc. BOOK NOTICES. The Geology of the Country near Hastings and Dungeness, by H.
