apparatus and schemed the plan. It had proved most efficient and 

 successful, as was evidenced by the fact of the keeping alive of so 

 delicate a fish as the herring for many months in the Aquarium. 

 Moreover, the plan was economical. K they had adopted the 

 principal of circulation, very large pumping power would be 

 requii-ed for such an immense body of water as was contained in 

 the tanks of the Brighton Aquarium. It had been constantly 

 remarked, in reference to the system of aeration, that only a small 

 quantity of air appeared to come in contact with the water ; but, 

 people who thought so, overlooked the fact that, by its means, there 

 was a continual circulation and absorption ; that the bottom water 

 was being continually brought to the sui-face ; that that which five 

 minutes before was down below was afterwards passing over the 

 top, and that the oxygen was, therefore, absorbed from the air 

 above the surface. So that, in fact, there was a circulation in the 

 tanks all over the building, which was a most important matter in 

 the successful keeping of live fish. He might say that a great 

 many things were being done at the Aquarium of which they were 

 not aware; and that the Directors were ever most anxious to 

 advance scientific knowledge. Their desire was to make the insti- 

 tution as successful in a scientific way as it had become as a place 

 of amusement. By means of the institution, scientific men wei'e 

 furnished with objects to enable them to carry on their investiga- 

 tions ; and, although it would be impossible for a resident Owen or 

 Huxley to mark everything that transpired within the institution, 

 some very important facts had been learnt or confirmed. The 

 problem set by Mr. Wonfor, as to the price of fish, was a most 

 difficult one ; and he thought that, for its solution, he must rather 

 go to the fish market early in the morning, than to the Directors of 

 the Aquarium. It was a difficulty which, in his opinion, rested with 

 the dealers, rather than upon the supply, of fish. With regard to 

 the oyster, he believed this mollusc bred as freely now as ever — 

 bringing forth as many as 800,000 young fry ; and, without going 

 altogether with his friend, Mr Frank Buckland, on the question of 

 of heat and tranquillity, he certainly thought it necessaiy that 

 there should be general warmth in the month of June, in order 

 that the young oysters might live. But we had cold mights in 

 June ; and, the climate of England being so variable, he rather 

 inclined to the belief that oyster cultui-e here would hardly be 

 successful, although the reverse was the case in the south of France,
