his walk along the shores, and spoke of the habits of 

 several of these animals, which showed a wonderful ca- 

 pacity for discovering localities fitted to their several 

 conditions. He described in a most interesting manner 

 the habits of the common ant, its methods of building, 

 etc. He also said, that several southern forms of sea- 

 weed are now found in Gloucester, and that many of the 

 mollusks and other species of animals, found along our 

 seacoasts, were imported, coming in various ways from 

 their original homes. In this connection he alluded to 

 the remarkable rapidity in the diffusion of Littorina litto- 

 rea; an interesting and valuable account is printed in 

 the Bulletin of the Institute, and will be found on pages 

 171-176 of Vol. XII. 



Hon. William D. Northend being called on by the 

 President responded in a humorous vein, — remarking 

 upon the work of the Institute, expressing his interest in 

 the object, and extending a cordial welcome. He re- 

 ferred to the geological features of the Neck, and hoped 

 that a systematic study of the rock formations would be 

 made. 



George M. Whipple, the Secretary of the Institute, 

 offered the following resolution which was unanimously 

 adopted. 



Resolved, That the thanks of the Essex Institute be ten- 

 dered to the Directors of the Marblehead Neck Associa- 

 tion lor the use of their hall, and to Frank R. Kimball, 

 Esq., for many courtesies so pleasantly rendered, and for

The Institute then adjourned, and the party returned 

 to Salem by ferry and cars, at pleasure.
