Geology. — The Department of Geology received a specimen of chal- 

 copyrite from Ascension Island ; one specimen of shell limestone from 

 the Barbadoes, and several pieces of lava from Porto Grande and 

 Horta, Fayal Island, Azores. So far as can be determined by simple 

 microscopic examination, these rocks are ordinary basalts. A study of 

 thin sections with a microscope might lead to different conclusions, but 

 these can not be well prepared at present, owing to the unusual press- 

 ure in other directions. This work will, however, be undertaken at 

 some future time. 



The Department of Marine Invertebrates received a collection of 

 crustaceans, echinoderms, worms, bryozoans, sponges, actinians, and 

 nullipore corals, from Azores and Cape Yerde Islands.
