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 Faune, 
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 Zodlogical Society, to Professor Solas, Dr. Joubin, and 
to Professor Biitschli. 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 Cymathoaz sent 
him and the late Professor Schiddte 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
