THE AQUARIUM LABORATORY AXD THE DIRECTOR'S OFFICE. 



The facilities of the Ac^uarium laboratory and collections have 

 been placed at the disposal of investigators from the city uni- 

 versities and elsewhere. Among those who availed themselves 

 of opportunities for original work were Prof. T. H. Morgan, 

 Prof. F. B. Summer, Prof. R. C. Osburn, Dr. T. H. Bean, Dr. 

 G. Eisen, Mr. C. Moreira, Mr. L. F. Ayson, and several stu- 

 dents. Mr. Ayson, Inspector of Fisheries of New Zealand, has 

 been most successful in acclimatizing American food and game 

 fishes in the waters of New Zealand, and has been charged with 

 the establishment of a small aquarium in connection with an 

 exposition to be held in Auckland. Dr. Eisen, of San Francisco, 

 made a detailed study of the methods of the Aquarium, to be used 

 m connection with his plans for the aquarium to be built in that 

 city. Mr. ]\Ioreira was in search of similar information for the 

 use of the aquarium in Rio de Janeiro. 



The Director has given his personal attention to the rather ex- 

 tensive correspondence of the Aquarium, endeavoring to reply 

 as satisfactorily as possible to the inquiries of the public in general. 

 He has also made constant examination of the work of the con- 

 tractors engaged in the improvement of the building. 



AID TO SCHOOL TEACHERS. 



Since the Aquarium came under the control of the Zoological 

 Society its collections and facilities for natural history study have 

 been placed very freely at the disposal of the teachers of biology 

 in the city schools. 



Acting upon the ofifer of living sea-shore animals from the 

 abundant stock in the reserve tanks of the Aquarium many teach- 

 ers called for specimens for class work. These have generally 

 been kept alive in small aquaria in. the school-houses. The interest 

 aroused by such object lessons in natural history has extended 

 until over loo teachers have provided aquaria in which to keep 

 the specimens procured. The Aquarium collector has no diffi- 

 culty in supplying an abundance of small marine creatures for 

 this purpose in connection w^ith his regular collecting for the 

 exhibition tanks. Mr. Spencer, of the Aquarium staff, has given
