PUBLICATIONS. 



Two Publications are issued under the direction of a Committee 

 of the Institute. From the year 1848 to that of 1860, two volumes 

 of the PROCEEDINGS OF THE ESSEX INSTITUTE were published. 

 These volumes contained the papers, on various subjects, which had 

 been communicated at the meetings of the Society, and the records 

 of the meetings. In April 1859, another publication was commenc- 

 ed by the Committee, under the title of THE HISTORICAL COLLEC- 

 TIONS OF THE ESSEX INSTITUTE, which contains abstracts from the 

 old Town and Church Records, old Journals and Diaries, and those 

 papers of an historical character which had been read at the meet- 

 ings. Before the close of the year this publication was issued in 

 regular bi-monthly parts and has now reached its seventh volume. 

 From 1860 to 1863. the third volume of the Proceedings was pub- 

 lished. With the commencement of the year 1864. the Proceedings 

 were somewhat changed in their character and issued quarterly. 

 The eight numbers published during 1864 and 1865 form volume 

 fourth, and contain the records of the meetings, with the quarterly 

 lists of the donations to the Museum and Library, and communica- 

 tions on Natural History and Horticulture which have been read be- 

 fore the Society. The Communications are distinctly paged to al- 

 low of their seperate binding if desired. Fifteen octavo plates and 

 a number of wood cuts accompany the fourth volume. 



The NATURALISTS' DIRECTORY is published with the Proceedings, 

 commencing with number five of volume fourth. It is paged by it- 

 self and is intended to be bound as a distinct work. When complet- 

 ed, it will contain as full a list as it is possible to obtain of all Natu- 

 ralists in the world, giving their address in full and the department 

 in which they are engaged. There will be three different orders of
