To the President and Fellows of Harvard College: — 



During the past year the usual courses of instruction have been 

 given at the Museum in the Natural History Laboratories. Those 

 in Zoology were given by Professor Mark, Dr. Slade, Dr. Daven-

 W. E. Castle, J. H. Gerould, H. V. Neal, and W. S. Nickerson. 

 Dr. W. McM. Woodworth has, as in previous years, taken charge 

 of the Laboratory work, and has given some lectures in the course 

 on Microscopical Anatomy. 



Professors Whitney, Shaler, Davis, and Wolff gave courses of 

 instruction in Geology, Palaeontology, Physical Geography, Mete- 

 orology, and Petrography. Messrs. Harris, Robert T. Jackson, 

 J. B. Woodworth, P. E. Dodge, C. E. Ladd, T. A. Jaggar, L. S. 

 Griswold, R. DeC. Ward, and H. L. Smyth were the Assistants in 

 these Departments. 



For the details of these courses of instruction, as well as of the 

 summer courses in Geology, I would refer to the accompanying 

 special reports of the Professors and Instructors. 



Professor Davis spent the past summer in Europe, with the 

 special object of studying certain rivers and valleys in England, 

 France, and Wurtemberg, and of attending the Sixth International 

 Geological Congress in Zurich. 



The Newport Marine Laboratory has, as usual, been open to 

 advanced students in Zoology. Eight students spent a part of 

 their time- in the Laboratory collecting material for their special 

 investigations, which they will continue at the Museum, and 

 prepare for publication. 



The Laboratory has been equipped with a microphotographic 

 apparatus. Dr. W. McM. Woodworth, who spent considerable time
