that an exhibit of sufficient interest to warrant opening the rooms 

 could probably be arranged. 



The equipment of the Lecture Room of the Geological Depart- 

 ment has been greatly improved by the installation of an electric 

 lantern, and the formation of an extensive collection of Photo- 

 graphs (the Gardner Collection), and the accumulation of a 

 great number of lantern slides specially selected by the different 

 instructors. 



I must again call attention to the crowded condition of the 

 Laboratories of the Zoological and Geological Departments, which 

 causes great loss of time to both instructors and students. Some 

 of the Assistants in those Departments are temporarily housed 

 in the rooms devoted to special collections, and do not have the 

 facilities for work to which they are entitled. No progress has 

 been made towards the equipment of the needed Vivarium and 

 Aquarium. 



In view of the increased demands made upon the Museum by

 on behalf of the Undergraduate Department, this allowance to 

 continue until the indebtedness of the Museum is extinguished. 



Our exchanges of publications with scientific societies are on a

 Library is now over twenty-four thousand. 



A list of the publications of the instructors and officers of the 

 Museum, other than those contained in our Memoirs and Bulle- 

 tins, will be found accompanying the special reports. 



For a complete List of the Publications of the Museum during 

 the past year I would refer to Appendix A. The number of our 

 publications has been much smaller than usual. We have only 

 issued seven numbers of Vol. XXV. of the Bulletin, — less than 

 one hundred pages. This is due in part to the number of unfin- 

 ished Reports of the "Albatross" Expedition, now in press, and 

 also to the inability of the Museum to provide for the printing 

 of the usual number of contributions from the Natural History 

 Laboratories. 



Owing to the financial straits of the Museum, Dr. Mark has been
