■which, as heretofore, has been ilhistrated or supplemented with prac- 

 tical field demonstrations. He has also delivered in the hall of the 

 Academy, a number of lectures before the Teachers' Institute of this 

 city, and contributed four lectures to the Friday Evening course of 

 the Academy. During the month of July be conducted a class in 

 the exploration of the Bermuda Islands, Avhich had hitherto received 

 but little attention from naturalists. The inquiry extended as well 

 to the zoological as to the geological features of the island group, 

 and has resulted in bringing to the museum a rich store of materi- 

 al, the greater -part of which is new to the collections. The details 

 of the exploration, to which reference is also made in the Curator's 

 Report, are being published in the Academy's Proceedings. 



The collections in the department of Invertebrate Paleontology re- 

 main pretty much as they were last year. A number of additions, 

 but none of any great significance, have been received. Perhaps 

 the most valuable of these is a collection of cretaceous plants from 

 Kansas, obtained from C. H. Sternljerg in exchange for certain vol- 

 umes of the Academy's Proceedings. Mention should also be made 

 ■of a fine selection of crinoids from the Carboniferous formations of 

 the central United States, generously given to the Academy by 

 Messrs, Wachsmuth and Springer, of Burlington, Iowa. 



The general condition of the collections is good. But here as in 

 almost all other departments of the Academy's ^Museum, additional 

 accommodations arc badly needed. 



Respectfully submitted, 



Angelo Heilpein, 



Professor of Invertebrate Paleontology. 



REPORT OF THE PROFESSOR OF ETHNOLOGY AND 



ARCHEOLOGY. 



During the past year the course of lectures usually delivered by 

 me was omitted owing to my absence from the city. 



The collections have received some but not extensive additions in 

 this department. It would be desirable and would benefit this 

 branch of instruction were all the ethnologic objects in the possess- 

 ion of the Academy arranged and classified separately from the 

 other collections, and according to the ethnic method of display. To 

 accomplish this the exclusive use of sufficient space would be needed
