REPORT. 



To The President and Fellows of Harvard College: — 



Most of the instruction and the opportunities for research in 

 Zoology, Geology, and Geography in Harvard University and in 

 Radcliffe College during the Academic year 1919-1920 were given, 

 as in recent years, in the Laboratories and Lecture Rooms of the 

 Museum. 



The sixteen courses or half courses in Zoology were taken by 

 317 students in Harvard University, and the seven courses or half 

 courses were taken by 88 students in Radcliffe College. 



In 1918-1919 these courses and students were: — 



Harvard: — 14 courses, 222 students. 



Radcliffe: — 6 courses, 81 students. 



In Geology and Geography thirty courses or half courses were 

 taken by 504 students in Harvard University and eight courses 

 or half courses were taken by 126 students in Radcliffe College. 



In 1918-1919 these courses and students were: — 



Harvard: — 19 courses, 333 students. 



Radcliffe: — 2 courses, 23 students. 



The field-work undertaken during the year, while limited in the 

 aggregate, has given some interesting results. Prof. P. E. Ray- 

 mond spent six weeks on the borders of Lake Champlain in Ver- 

 mont and New York, collecting in the Chazy and nearby forma- 

 tions. On Isle La Motte, Vermont, he secured the largest known 

 Palaeozoic sponge and some corals from the oldest known coral 

 reef. Professor Raymond also discovered an apparently new 

 locality for Palaeozoic fossils in Topsfield, and collected a number 

 of specimens from some of the already known localities in the 

 vicinity of Boston. 



For somewhat more than three months, February to June 1920, 

 the U. S. Fisheries Steamer Albatross carried on a successful 

 exploration in the Gulf of Maine and adjacent waters. As in 

 recent years, the scientific work of the Albatross in the Gulf of 

 Maine was under Dr. H. B. Bigelow's direction, and he was in
