hereabouts was covered with a vast field of ice, which 

 gradually moved southward. One of the evidences of 

 this moving field of ice is the rounding of the large stones 

 all over New England toward the north, and their ragged 

 precipitous character towards the south ; also the presence 

 of bowlders which evidently do not belong to this region. 

 Reference was also made to the glaciers of Greenland 

 and Switzerland. 



Prof. Morse exhibited specimens of the I^iq)iUa mus- 

 corum, which he had found on the island during the day, 

 and considered this a new locality for this species. A 

 communication prepared by him since the adjournment, 

 on " The gradual dispersion of certain Mollusks in New 

 England," contains a description of this Pujnlla, and is 

 appended to the report of this meeting. 



Rev. Joseph Banvakd, of Neponset, formerly pastor 

 of the Central Baptist church of this city, made some 

 excellent and practical remarks regarding the possibility 

 of every one being able to gather much scientific knowl- 

 edge, by keeping the e^es open and cultivating the 

 habit of close observation. He urged the young people 

 present to study the simple things in nature, and in so 

 doing, they would not only find great pleasure, but great 

 profit. 



Mr. N. a. Horton, of the Salem Gazette, after a few 

 appropriate remarks, oflfered the following resolution 

 which was unanimously adopted. 



Resolved^ That the thanks of the Essex Institute be 

 tendered to Col. William L. Palmer, for his polite invi- 

 tation to hold a field meeting on Lowell Island, and for 

 the courtesies extended to the members and their friends 

 on this occasion.
