 tection of glass. If there are only a few 

 of these they may be successfully 

 grown in cisterns placed in a stove ; 

 but if the collection be extensive, it re- 

 quires a separate edifice. The tank 

 system of lieating by hot water offers a 

 very superior mode of keeping the wa- 

 ter at a fittmg temperature. The leaden 

 cistern in which the plants are sub- 

 merged may rest readily upon the slates 

 forming the cover of the tank. 



Mr. Loudon recommends an aqua- 

 rium to be thus constructed: "The

 most needless to add, that exotic aqua- 

 tic fowls and fishes might be kept in 

 such an aquarium, and either of the sea 

 or fresh water rivers, according as salt 

 water or fresh was used. It may be 

 thought by some that the machinery 

 would be intricate and troublesome ; but
