Very few improvements have been made to the aquai'ium in the 

 past few years, and in comparison with the elaborate aquarial displays 

 at the World's Fair in Chicago and the Pan-American Exposition at 

 Buffalo the Central Station aquarium is a very small affair. It should 

 be greatly enlarged and the salt-water tank supplemented with an 

 additional one, so that during the year, while the stock of marine spe- 

 cies is in the aquarium, the salt water can be entirely renewed every 

 few months. A refrigerating s3\stem is also recommended, in order 

 that the various species of the Salmonidse may be carried in the fresh- 

 water aquaria during the sunmier months. 



The following is a list of the marine and fresh-water species exhib- 

 ited at Central Station during the year: 



Salt-water species. — Jumping mullet, croaker, hog-choker, red drum, sea-robin,
