OCEAN GAEDENS , 



equal success with the green, as I shall state when 

 describing them. Under the existing difficulty, 

 Mr. Warrington found it necessary to aerate the 

 water by other means, many processes being equally 

 available; such as injecting fresh- water from a 

 syringe, or establishing a drip, of some height, from 

 a vessel containing a supply of entirely fresh- water. 

 Mr. Warrington also discovered, in the course of 

 these experiments, the necessity that the light 

 should pass directly through the surface of the 

 water to the plants, as in natural ponds and seas — 

 a very important step in the successful manage- 

 ment of Aquaria; and he therefore had a slab of 

 slate adjusted to the side of his tank which stood 

 next to the light. 



These successful experiments, both in fresh-water 

 and marine Aquaria, assign to Mr. Warrington, 

 beyond dispute, the credit of being the originator, 

 or inventor, if the term may be so used, of these 

 charming additions to our conservatories, corridors, 

 and even living-rooms, to which they are certainly a 

 much more attractive and instructive addition than 

 the old globe of blank water, with its pair of gold- 

 fish swimming round and round in ceaseless gyra- 

 tions, tiresome to behold, in the vain hope of 

 escaping from their glaring and inconvenient prison ;
