Whitney has also made preparation for a thorough course in 

 Lithology, and has engaged Mr. Wadsworth as his Assistant in 

 that department. By Professor Whitney's care, a large numl^er 

 of rock sections have been made for the use of the students 

 in Lithology: a part of his private lithological collection has 

 been unpacked, and made available at the Museum, thus placing 

 the lithological department on a very creditable footing. A 

 beginning of a special geological library has also been made by 

 Professor Whitney, which, though incomplete as yet, is probably 

 the best in the country. The Corporation have appropriated 

 the larger part of the expenses of bookcases for its reception. 

 Professor Whitney, besides defraying the greater part of the 

 expenses of publishing Vol. VI. Part 2 of the Memoirs, has 

 also, in addition to other expenses, provided himself the needed 

 Assistants for the instruction in his department ; the funds at 

 present at the disposal of the Geological Department not being 

 sufficient to more than pay the salary of the Professor, a con- 

 dition of things which, it is hoped, will not continue long in so 

 important a department of the Museum. 



Professor N. S. Shaler has given instruction in general 

 geology during the past year to seventy undergraduates and 

 four graduates, the work consisting of lectures and field- 

 work. In Palaeontolog}^ there were fourteen undergraduates 

 and three graduates who received instruction by lectures and 

 laboratory work. Professor Shaler has also continued his usual 

 summer course in connection with the Geological Survey of 

 Kentucky. 



Dr. William James gave instruction during the past year in 

 Comparative Anatomy and Physiology of Vertebrates to a num- 

 ber of undergraduates, varying from eighty to ninety. The 

 course was similar to th^ given the previous year. The more 

 practical and human parts of the subject seem to awaken the 

 most general interest. Since the resignation of Professor 

 McCrady, the instruction in zoology has been divided between 

 Dr. Faxon and Dr. Mark ; Dr. Faxon taking charge of the 

 Radiates and Crustacea, Dr. Mark of the Mollusks and air-breath- 

 ing Arthropods. 



Aside from the work of instruction. Dr. Mark gave consider- 

 able time, especially in the first half of the year, to the col- 

 lection of Vermes in the Museum. This collection has been
