It contains nearly a hundred wall tanks and seven large floor 
pools. The collections embrace both fresh- and salt-water spe- 
cies, and constitute the largest single collection of living fishes.

in summer. There are usually over 150 species of native and 
tropical fishes on exhibition. 
An institution so popular should be adequately maintained,
