REPORT ON THE GEOLOGICAL DEPARTMENT. 



By Josiah D. Whitney, Sturgis-Hooper Professor. 



During the College year 1884-85 a course of forty-eight 

 lectures on Economical Geology was given by the Sturgis- 

 Hooper Professor, which was attended by about twelve College 

 students, mostly Seniors. This course was made more popular 

 than it had before been, and special attention was given to the 

 mineral and metallic resources of the United States, and to 

 their economical development. 



There were no special students in Geology or Lithology. 



Doctor Wadsworth, after the completion of the first part of 

 the " Lithological Studies," of which there was given in the 

 last Report of this Department a full account, went to Europe, 

 where he spent most of the year. His object was to make 

 himself acquainted with the leading European lithologists, and 

 to examine the most important collections in this department 

 in England and on the Continent. Every facility was given 

 him for the study of such of these collections as he had time 

 to visit, and especially those of Vienna, Berlin, and London. 

 Dr. Wadsworth has published several lithological papers during 

 the year. He has now left Cambridge to enter upon the duties 

 of the Professorship of Geology in Colby University, at Water- 

 ville, Maine ; but the publication of the " Lithological Studies" 

 can be resumed at any time, if the necessary pecuniary arrange- 

 ments can be made. A large portion of the work is already 

 done, and when published it will complete the eleventh volume 

 of the Memoirs of the Museum. The Sturgis-Hooper Professor 

 has published one or two brief geographical papers, and also 

 prepared the definitions in Physical Geography, Geology, Min- 

 ing, and Metallurgy, for the new dictionary to be issued by 

 the Century Company of New York. As a special subject of
