surroundings. 
THE FRESH WATER AQUARIUM AT JAMAICA POND.

the stems of water plants, and by means of curious 
changes of structure finally become suited for flying in 
the air. 
Fresh-water animals and plants are modified descend- 
ants either of marine or terrestrial organisms, and it is 
intended to exhibit this striking but rarely considered fact 
by series of living objects side by side. Even the steps 
of the transformations by which certain shrimp-like, brine- 
inhabiting animals become fitted for living in fresh water 
can be directly exhibited in a series of aquaria. The edu- 
cational value of such displays, which have not, so far as

display of animals sufficiently extensive to include not a
