The completion of our 12th Volume affords a convenient 

 opportunity of giving a list of the dates of the publications of the 

 Club, for the information of new Members and Librarians. 



The Club was founded on January loth, 1880, and its first 

 publication was rhe Inaugufal Address delivered by Mr. R. 

 Meldola, on February 28th, 1880. This was published as a 

 distinct pamphlet, and it also formed pp. 1-26 of Volume I. of 

 The Transaction of the Epping Forest and Comity of Essex Naturalists 

 Field Club, of which Part I. appeared in September, 1880, and 

 the following parts at irregular intervals. With Volume III. 

 the shorter title of The Transactions of the Essex Field Club was 

 adopted, in accordance with the change in the title of the Club. 

 In the first three volumes, the Transactions and Proceedings had 

 but one title-page, although with distinct pagination ; but, in 

 order to facilitate editing, it was resolved to separate them, 

 and Volume IV. of the Transactions and Volume IV. of the 

 Proceedings were so issued. In January, 1887, however, the 

 publications were finally combined in The Essex Naturalist, of 

 whicli the 12th Volume is now concluded. The volumes were 

 annual up to 1894 ! "^^^^ two years are included in each volume. 



In future the Essex Naturalist will be issued at regular 

 quarterly intervals, on or about the 20th of April, July, October, 

 and January. The Council of the Club has decided to charge 5s. 

 per part to non-members, but the journal will be sent free by 

 post to Members. Therefore those wishing to have the Essex 

 Naturalist should become Members of the Club. 



The old series, therefore, consists of three volumes of 

 Transactions and Proceedings combined, with single title-page for 

 each volume, and one each of Transactions and Proceedings with 

 separate title-pages, together with appendices. The parts were 

 issued as follows, and the appendices indicated should be bound 

 up with each volume : —
