to some valuable specimens of Fish, that had been received 

 from the Smithsonian Institution, among which he spoke of 

 the genus -^Sc/aV^e, from the river Nile; specimens of young 

 Amia, from Illinois ; and a Goniodont, from Para river, &c. 

 Dr. W. mentioned, also, that we had received from C. Gi- 

 rard, of Washington, some of his original specimens of Po- 

 motis ohesus and Esox ornatus, which established the iden- 

 tity of the former with the Bryttus lately taken in this coun- 

 ty, and that of the latter with the Esox fasciatus of DeKay. 



Dr. Wheatland likewise alluded to the elegant collection 

 of bird-skins from the East Indies, lately presented to the 

 Institute by Mrs. Charles Mugford, of this city, which is 

 considered one of the most valuable collections ever made to 

 this Department, consisting of fifty-two species and about 

 one hundred specimens. He concluded by proposing a vote 

 of thanks to Mrs. Mugford, which, after a few remarks from 

 the Chair, who spoke of the excellent state of preservation 

 of the specimens, and of their value in a scientific point of 

 view, was unanimously passed. 



Mr. George P. Bradford presented a specimen of the Acer 

 striatum, or Moose Wood, taken from one of a number of 

 trees found growing near the boundary between Salem and 

 Swampscott. The Chair expressed his gratification at the 

 receipt of this specimen, the knowledge of this species being 

 found in this immediate neighborhood, was communicated 

 to him by Mr. B. To whom also, was due the discovery, in 

 North Salem, the last summer, of the Thlaspi arvense, a 

 rare and British species of Shepherd's Purse, with large 

 conspicuous, and flat, circular pods. 



The Institute then adjourned.
