MUSEUM OF COMPARATIVE ZOOLOGY.

Professor Raymond will give part of his time to teaching, and part 

 to work in the Museum of Comparative Zoology. During the year 

 1911-1912 he gave one advanced course in palaeontology. 



Assistant Professor Johnson was absent on leave during the 

 second half-year, and at the end of the year resigned to accept an 

 Associate Professorship of Physiography at Columbia University. 



The Department is indebted to the family of Mr. Edward 

 Wigglesworth for the gift of a Wiechert seismographic clock, which 

 was installed in the station this spring. Mr. Sayles presented 

 a collection of beach pebbles, bored by a lithodomous mollusc, 

 from Coronado Beach, San Diego, Calif. Mr. Philip S. Durfee 

 deposited a collection of preglacial, or interglacial, decayed rock 

 specimens found by him beneath the Pleistocene glacial drift south 

 of Forest Hills Square in the Metropolitan district. 



The Student Palaeontological Collection has received the follow- 

 ing donations: — Two Cambrian trilobites from Dr. C. D. Walcott, 

 2 Cambrian trilobites from Mr. W. P. Haynes, 24 recent shells 

 and 33 fossils from Mr. Joseph Murdoch, and 5 Cambrian trilo- 

 bites from Mr. Hay ward. Dr. John M. Clarke gave a set of the 

 palaeontological memoirs of the New York State Museum. 



Seventeen courses and half-courses in Geology and Geography 

 were elected by 26,8 students in Harvard University, as against 315 

 in the previous year. Three half-courses offered in Radcliffe Col- 

 lege were taken by 23 students, as against 21 in 1910-11. Messrs. 

 F. H. Lahee, W. P. Haynes, D. C. Barton, Edward Wigglesworth, 

 and E. G. Linsley were Assistants during the year.
