that (in so far as experiments illustrative of natural 

 science were concerned) the suggestions of Ingen- 

 hauss remained tolerably dormant. 



It was not till the year ISSS, that Professor 

 Daubeny communicated, to the British Association 

 at Cambridge, a paper concerning some new re- 

 searches prosecuted in the same direction ; and not 

 till 1837, that Mr. "Ward became the first to apply 

 the principle to any purpose analogous to that of 

 the Aquarium. In that year he made a report to 

 the British Association, on the hermetically closed 

 glass cases in which he had succeeded in growing 

 many classes of plants, and keeping them in a 

 healthy state without any fresh supply of air. He 

 stated, at the same time, his belief that certain 

 classes of animals would live and thrive under 

 similar circumstances. This was the first direct 

 hint towards the formation of a closed Vivarium, 

 whether atmospheric or aquatic. 



In 1842, Dr. Johnston satisfactorily proved the 

 true vegetable nature of Corallines by observing 

 their growth in a vessel containing sea- water ; and 

 thus was established the first true Aquarium. With 

 the experimental tuft of Coralline was a small frond 

 of a green Jllva^ and numerous Hissoce^ &c., and 

 several Annelids afterwards appeared, having been.
