which, as heretofore, has been illustrated 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, which 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 T 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 w 7 ere 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. Sternberg 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 are badly needed. 
Respectfully submitted,

Professor of Invertebrate Paleontology. 
REPORT OF THE PROFESSOR OF ETHNOLOGY AND 
ARCHAEOLOGY. 
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 w r ould be desirable and w r ould 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
