ANNUAL REPORT. 251 numerous field-botanists present at the meeting mentioned above, that the Doctor may be spared to carry on his good work and to assist at these gatherings for many years to come. "The Mammals, Reptiles, and Fishes of Essex."—The final arrangements with Dr. Laver for the publication of this book as one of the " Special Memoirs " series were completed during the year. The Agree- ment with the author provides that the publishing price should be 10s. 6d. nett ; that the subscription price to the general public should be 7s. 6d. and the subscription price to the members of the Club 6s. The Club has sub- scribed for 50 copies at 6s. (£15), such copies not to be sold until the expira- tion of six months from the date of publication, and then only to members of the Club, but it has been agreed that this prohibition shall not apply to the sale of sets of the Club's publications to non-members. The Council have pleasure in acknowledging the kindness of the President, Mr. Howard, who has promised to contribute £5 towards the cost of the 50 copies sub- scribed for by the Club as above. The book was published on March 7th. The list shows that members of the Club have subscribed for 119 copies, a result which may be considered satisfactory. The Council have to thank Dr. Laver for the care he has taken in the production of the volume, which cannot fail to be of great value to Essex Naturalists, and which will, it is hoped, be an encouragement and help in the further study of our county animals. In connection with the publication of this book the Council have reduced the price, to members, of the Birds of Essex to 7s. 6d. ; the two volumes form a complete guide to the vertebrate fauna of Essex. The special value of such works is that they emphasise the deficiencies in our knowledge. For instance, Dr. Laver's list of 113 Fishes hitherto satisfactorily determined as inhabitants of the rivers and sea-board of Essex is probably far too small, bearing in mind how much remains to be discovered with regard to the marine fishes ; good work might be done by those living near the coast or spending their holidays there, in the investigation of this interesting and extremely important class of animals, and the Council strongly recommend the subject to the attention of members having opportunities for observation. The Club's Local (County) Museum.—Very important develop- ments have taken place with regard to the Club's County Museum. The conditions under which an offer was made to the Corporation of Chelmsford, together with a statement of the position of affairs were fully set out in the last Annual Report (Essex Naturalist Vol. X., pp. 18-20). It will be sufficient to say on the present occasion that the Club's offer was not accepted by the Corporation of Chelmsford. The Council then made precisely the same offer to the Corporation of West Ham, and this offer was accepted by that Corporation, and Mr. Passmore Edwards has generously offered to con- tribute a sum of £2,500 towards the cost of building a suitable Museum to contain the Club's Collections, adjoining the Technical Institute in West Ham, on condition that the Corporation maintains the building for that purpose. The Corporation of West Ham have accepted Mr. Edward's offer, and the proposed Agreement between the Corporation and the Club is now being drafted. The main conditions are (a) On the part of the Corporation : To dedicate the building to the purposes of a Museum of Local (Essex) Natural History and Archaeology ; to warm, light, and provide for the care-taking of
