Mr. T. S. Hunt, upon being introduced to the Society 

 by Dr. Bacon, made some remarks upon the continuation of 

 the metamorphic rocks of the New England Stales, into 

 Canada East ; upon the composition of Dolomites, the differ- 

 ent theories of their formation, &c., and gave his own 

 theory of their production. 



The President, from the Committee appointed to consider 

 the proposal of exchange of geological specimens, with Sir 

 William Jardine, of Scotland, reported, that after consulta- 

 tion with Mr. Bouve, they had concluded that it was inex- 

 dedient to make such exchange at present. 



The President remarked that some time since he had 

 stated that, though a matter of great doubt, he thought it 

 probable that, at some time, the impressions of insects and 

 their tracks would be found in solid rock. Since making 

 that observation, he had received several small slabs, upon 

 which are tracks, apparently, if not really made by insects, 

 'which resemble the tracks of the cricket, cockroach, or 

 beetle. Upon several specimens, these tracks are of the 

 same width and general appearance ; and the individual foot 

 prints, if they may be so considered, are alike in all the 

 specimens. These specimens were from the banks of the 

 Connecticut. One of the slabs likewise presented an im- 

 pression very much like that of a spider's body and extremi- 

 ties. 



Mr. Bouve said that he had seen tracks of the cricket 

 upon the sand of the sea shore, of similar appearance to 

 the impressions in question. 



Messrs. Samuel S. Wilson and George H. Marden were 

 elected Resident Members.
