RIVER GARDENS; 
I have mentioned the fine Carp in the ponds at the 
Chateau of Fontainebleau; and M. Orbigny* men¬ 
tions others as fine, and probably of as great age, 
at Chantilly and Pontchartrain. The Carp in the 
Dniester and Volga attain to a very large size, not 
infrequently weighing as much as seventy pounds. 
The Crucian Carp, Cyprinus curassia , by the 
French termed Carpe carcissin , and in Sweden, 
Carussa or Carouche , is another species, generally of 
inferior size, which is well suited to the Aquarium; 
as is likewise another distinct species, the Prussian 
Carp, Cyprinus gibelio , which is a very hardy fish, 
and it is said will live for thirty hours out of water. 
Our old favourites, the Gold and Silver Fish, are 
of the Carp family ( Cyprinus auratus ), hut I shall 
speak of them separately in another place. 
The Tench (Plate IV., No. 2,) is also easy to keep 
in a moderately sized glass tank. His fine deep 
bronze tones, touched here and there with a sparkle 
of gold at the edge of the scales, as though 
brightened by his passage through the water, give 
to him a richness of hue that produces a good 
effect among the foliage of the tank; while his 
small and delicate scaling forms a remarkable con¬ 
trast to the large horny scales of the Carp. In the
