Note.— Our correspondent is not very clear; he 
does not state whether he wants a sea-water or 
fresh-water aquarium. The following general 
suggestions are offered, however: We would ad- 
vise about one bunch of plants to every three gal- 
lons of water, and three small fishes to each gallon 
of water. By a bunch of plants is meant such as is 
sold by the dealers. Valisneria is recommended 
above all other plants for the purpose ; the rivers 
are full of this growth. Nitella, anacharis, and 
utricularia are also excellent plants for the pur- 
pose. In the matter of fish, try catfish preperel, 
shiners, dace, minnows, rockfish, sunfish. and 
tadpoles, all as small as can be obtained. Apply 
to Mr. Taxis, of your city, for further informa- 
tion ; he is an expert in these matters, and you 
will find him a gentleman in every respect.
