424 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



with an arrangement to enable any one or more to be iso- 

 lated and emptied for examination without wasting any wa- 

 ter or interrupting the circulation. This, by reason of its 

 great dimensions, and also by reason of its coolness and 

 darkness and the absence of life in it, will keep the entire 

 aquarium arrangement in good order, since the water will 

 be constantly flowing in and out of it. It will travel a dis- 

 tance of nearly three miles between the beginning and end 

 of its circuit, in the course of which a portion (about one 

 tenth) will be lifted about seven feet, and be made to enter 

 each tank with force through fine jets, which will carry air 

 into the tanks in a finely divided state. The total quantity 

 of water in use, including that in the proposed fountain 

 basins, will be nearly a million gallons, of which about three 

 fourths will be sea- water, to be brought from Brighton in 

 casks by Mr. W. Hudson, at the rate of a railway train of 

 twelve trucks full every day for six months. 



Mr. A. Bedborough is the architect, Messrs. Lucas are the 

 builders, Messrs. Leete, Edwards, & Norman furnish the ma- 

 chinery and circulating apparatus, Messrs. Doulton & Co. 

 supply the ornamental tiles. The rock work is furnished by 

 Mr. Wills ; Professor R. V. Tuson is the chemist of the es- 

 tablishment, the whole being under the direction of Mr. 

 Lloyd himself, well known from his connection with the 

 Hamburg establishment and others which he has organized. 

 For the proper supply of animals for this and other aquaria, 

 it is contemplated to arrange two traveling aquaria one for 

 Great Britain and the other for the Continent to convey 

 living marine animals from the Naples aquarium, where a 

 great variety of species can always be had. According to 

 Mr. Lloyd, the old-fashioned plan of maintaining a proper 

 supply of oxygen for the animals in aquaria, by the intro- 

 duction of living plants, is practically inapplicable to large 

 establishments, the true theory being that of keeping the 

 water cool and clear, and properly charged with atmospheric 

 air in a large, dark reservoir. 



In addition to the aquarial display at Westminster, there 

 will be a picture and fine art gallery, and accommodations 

 for flower shows, etQ. Musical entertainments will also be 

 given. Mr. Lloyd protests against the admission of the lung- 

 breathing aquatic animals, such as seals, porpoises, and the
