RIVER GAEDENS; 



I have mentioned the fine Carp in the ponds at the 

 Chateau of Pontainebleau ; and M. Orbigny* men-

 Dniester and Volga attain to a very large size, not

The Crucian Carp, Cyprinus curassia, by the 

 Prench termed Carpe carassin, 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, Cyprinm 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 Pish, are 

 of the Carp family (Cyprinus auratus), but 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

 small and delicate scaling forms a remarkable con-
