Very few improvements have been made to the aciuarium in the 

 past few 3'ears, and in comparison with the ehiboratc a<iuarial disj)lays 

 at the World's Fair in Chicago and the Pan-American P^.xposition 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 acpiarium, the salt water can be entirelj'' renewed every 

 few months. A refrigerating system is also recommended, in order 

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

 water aquaria during the summer months. 



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

 ited at Central Station during the year:
