insects in gum COPAL. 



Mr. George E. Ashby, in connection with his exhibits, 

 remarked, that the main supply of Gum Copal is obtained from 

 sand, at the depth of several feet, along the coast of Zanzibar, 

 in localities where no trees are now found. The Gum has an 

 oxydized and pitted surface, to which the sand does not adhere. 

 Copal is more recent than Amber. The insects enclosed in 

 Amber belong to extinct species, while those enclosed in Copal 

 belong frequently to living species. The price of Gum Copal 

 is One Dollar or more a pound, depending upon the trans- 

 parency. 



habitat of volvox. 



Mr. J. D. Hyatt mentioned a pond, in a marshy tract, just 

 beyond a ridge on the easterly side of the Harlem Railroad, and 

 one-quarter of a mile beyond Jerome Park Station on that road, 

 as the only place known to him in this vicinity where Volvox can 

 be found in abundance.
