THE MARINE AQUARIUM. 



(SALE LIST.) 



19 & 20, PORTLAND ROAD, 



REGENT'S PARK, 



LONDON. 



MR. W. ALFORD LLOYD begs to announce that he has made very exten- 

 sive arrangements for the sale of Living Marine Animals, 8ea-Weeds, Tanks, 

 and all other accessories for the study of Aquarian Natural History. 



Mr. Lloyd ordinarily keeps a stock of fifteen thousand specimens, compris- 

 ing two hundred genera, acclimated in fifty large plate-glass tanks, aggregating 

 more than a thousand gallons of sea water. The peculiarity which distinguishes 

 this collection above that which any other single spot can furnish, and which 

 renders it an object of attention not only to the amateur and student residing 

 in London and in other inland places, but also to naturalists living at distant 

 parts of the coast, is, that it is the result of an organized body of gatherers, 

 posted at intervals in the richest localities ; and thus onr Marine Fauna and 

 Flora are very adequately represented, as to variety, in the Metropolis, 

 and may be had from thence much more advantageously than from the 

 coast direct, inasmuch as the specimens are selected with the special view of 

 their respective capabilities of enduring confinement. Arrangements with 

 foreign correspondents are also in course of progress. The most delicate 

 organizations may be sent by rail or by post with perfect safety. 



The discovery of a mode of making Artificial Sea- Water gives large facili- 

 ties for the successful prosecution of the study. Much time, therefore, has 

 been spent in assimilating it to the condition of the actual water of the 

 ocean, so that it is offered as an analytically correct compoundj which 

 thoroughly answers every purpose, and which improves in good quahties the 

 longer it is kept in use unchanged. Thus the permanent maintenance of a 

 collection of Living Marine Animals and Algae is rendered a far more easily 

 attainable matter than even the domestic culture of flowers. To render this 

 yet more practicable in the hands of inexperienced persons, Mr. Llotd
