exhibited specimens of a Gum from California, which was 

 said to resemble in its properties Gum Arabic, and of a 

 bark which was stated to have the mucilaginous charac- 

 ter of Slippery Elm Bark. The specimens were samples 

 of some presented to the California Society of Natural 

 History by Dr. Thomas Payne, of Mariposa, Cal., and 

 forwarded to Dr. Brewer by Dr. Holden ; they were re- 

 ferred to Dr. Hayes for analysis. 



Mr. Thomas Hollis (after a moment's examination of 

 it) stated that the bark bore considerable resemblance to 

 the Wild Cherry Bark. It had a similar odor, but it was 

 not so astringent. The mucilage from this is not imme- 

 diately extracted in the mouth, but, as is the case with 

 the Wild Cherry Bark, it may be developed after some 

 hours maceration in cold water. The wild cherry like- 

 wise exudes a gum similar to this. 



Dr. A. A. Gould presented, in the name of William 

 M. Bailey, Esq., of Providence, a Photograph of his 

 brother, the late Prof. Bailey of West Point. The thanks 

 of the Society were voted for the gift. 



Messrs. Theodore Metcalf, George N. Davis, and 

 Thomas D. Morris were elected Resident Members.
