Besides the water-plants thus briefly described in this 

 chapter, there are of course others which would also be both 

 useful and ornamental in 

 aquaria; but enough has 

 been said, I hope, to give 

 the novice in aquarium 

 matters am idea of what 

 kinds of plants to look for, 

 where they may be .found, 

 and how they may be intro- 

 duced into his tanks.*

* At the time this article appeared in The Bazaar the Editor of that paper 

 appended the following note : "At Green's Conservatory, Covent Garden, we saw 

 the other day a small Water Sela^nella, which was very pretty. It was exactly 

 like fragments of a small variety of Selaginella or Club Moss, and grew freely on 

 the surface of the water, like duckweed." I have tried this plant, and cannot 

 speak favourably of it.
