CHAPTER XVII. 



THE AQUARIUM AND WATER PLANTS. 



Proportion of Animal and Vegetable Life. Form. Construction. Di- 

 mensions. Situation. Oxygenation. Sunshine. Planting. Plants 

 suitable for the Parlor Aquarium. Limnocharis Humboldtii. Pro- 

 curing Plants. General Directions. 



T is not within the scope of our 

 present work to treat of 

 the general construction of 

 Aquaria, or their man- 

 agement in relation 

 to their living tenants. 

 Equally out of place will 

 it be to treat of the growth of 

 algae, or sea weeds, or the inhab- 

 itants of marine or salt-water aquaria. 

 We can only consider the aquarium, at 

 present, as a means of growing in perfection, in the parlor, 

 meadow and water plants, leaving for others the pleasing 

 duty of describing animate life in connection therewith.
