For the details of the courses I would refer to the accompany- 

 ing special Reports. 



About nine hundred volumes have been added to the Library 

 of the Museum during the past year. This is exclusive of the 

 books ordered by the College Library for the Natural History 

 Department. 



The Europeo-Siberian Room has been opened to the public 

 during the year. This, with the exception of the Marine Faunae, 

 completes the arrangement of exhibition-rooms devoted to zo- 

 ological collections. 



Collections of Fishes and of Echinoderms have been sent to 

 the Museums of Stockholm, Bergen, Brussels, Paris, Copen- 

 hagen, London, Florence, Milan, Gottingen, Hamburg, and 

 Vienna, to the Smithsonian, to New Haven, and to Pro- 

 fessor Ward of Rochester. Exchanges have also been con- 

 tinued with our Australian correspondents. 



For the High School of Gloucester a good typical collection 

 of Mollusks and of Echinoderms was made by Messrs. Hamlin 

 and Fewkes. 



Materials from the Museum collections have been sent for 

 study to the United States Geological Survey, to Dr. Dobson 

 of the Zoological Society, to Professor Solas, Dr. Joubin, and 

 to Professor Butschli. A number of persons have received 

 invoices from the Entomological Department. In view of the 

 number of specialists applying for types contained in the 

 Museum, it will soon become impracticable for us to send out 

 such material, unless our working force can be increased, as this 

 work is constantly making greater claims upon the Assistants, 

 leaving them no time to attend to the regular work of their 

 departments. 



Dr. Meinert has returned the collection of Cymathoase sent 

 him and the late Professor Schiodte for their Monograph of the 

 group. Professor Lesquereux has returned to the Museum the 

 large collection of fossil plants collected in 1883 by Professor 

 Lakes of Golden, which he had kindly consented to examine 

 and to identify. He has retained the more interesting species, 

 to be figured in a memoir he is preparing for the United States 

 Geological Survey on the fossil plants of the Dakota group. 

 The spiders sent to Count Keyserling have also been returned 

 to the Museum. Mr. P. H. Carpenter has returned the Stalked
