man. These similarities gave rise to a most suggestive 

 discussion. Some of the specimens (belonging to the 

 Peabddy Museum, in Cambridge) shown by the lecturer 

 were very curious and valuable. The various questions 

 proposed by Prof. Morse, Rev. Mr. Bolles and others, 

 which were promptly answered by the lecturer, gave a 

 very pleasant variety to the evening, and were very in- 

 structive. 



Eegular Meeting, Monday, April 16, 1877. 

 Meeting this evening. The President in the chair. 

 Records read. Correspondence and donations to the 

 Library and to the Museum were announced. 



There were also exhibited collections of grasshopper 

 eggs, taken from prairie soil in Plymouth Co., Iowa, three 

 hundred miles west of Dubuque, received from Gen. 

 Horace Poole of Dubuque, who thought that some of the 

 members of the Institute would desire to observe the 

 development of these insects, now that the matter has 

 become of such importance as to enlist the attention of 

 the National Government, which has just appointed a sci- 

 entific commission to investigate the grasshopper pest. 

 The President called on Prof. A. S. Packard, recently 

 appointed a member of this commission, who briefly de- 

 scribed the hatching of the eggs, and spoke of the habits 

 and the great size of the swarms as they fly through the 

 air. He jilso replied to several questions which were pro- 

 posed. 



The remainder of the evening was occupied by Mr. J. 

 S. Kingsley in a lecture on the Crustacea, illustrated by 

 blackboard drawings. 



Miss Ella Farman was elected a member.
