THE NEW YORK AQUARIUM 



complete control of the institution and is responsible for 

 its status as a museum. The annual maintenance fund of 

 the Aquarium is provided by the City of New York. The 

 exhibits are provided by the New York Zoological Society. 



The Aquarium is open free every day in the year: 9 a.m. 

 to 5 p.m., from April to October, and 10 a.m. to 4 p.m. from 

 November to March. 



The building is circular in form with a diameter of 205 

 feet. Seven large pools, containing turtles, crocodiles, 

 large fishes and marine mammals, occupy the main floor, 

 and a series of large, well-lighted wall tanks— thirty to forty 

 around the main floor, and fifty to sixty on the gallery 

 above — present to the visitor a comprehensive view of 

 American fishes, including marine, fresh-water, tropical and 

 northern species. 



The equipment includes facilities for heating sea water 

 in winter for the tropical fishes; for cooling fresh water in 

 summer for the natives of mountain lakes and rivers; for 

 pumping and filtering brackish water from New York Bay 

 for the large floor pools, and for maintaining a reservoir of 

 pure sea water for the salt-water wall tanks. There is also 

 an air compressor for supplying extra aeration to all tanks 

 when necessary.
