6ontains the anemones, for the finest specimens of which the Committee are again indebted 

 to the Directors of the Brighton Aquarium, who have given every assistance to procure a 

 thorough and handsome collection. It will be well, perhaps, for those visitors who take any 

 interest beyond mere curiosity in an aquarium to try and realise for a few moments the 

 seemingly overwhelming difficulties which appear to crop up on all sides to those who 

 undertake the formation of one. So numerous are the questions which have individually to 

 receive the deepest discussion, that it is quite impossible to consider them in a short preface ; 

 but it may be as well to mention some of the few principal ones. The first question is the 

 quantity, quality, and direction of the supply of light, which, if not of the most perfect and 

 direct kind, will entirely prevent the finest aquarium from ever becoming a success. Second 

 only in importance are the questions of foundation and drainage, as the slightest error in 

 either of these causes not only leaks in masonry, but signs the death-warrant of the costly 

 plate glasses. Next the temperature and quality of the water to be used give a vast amount 

 of anxiety, and when, in spite of all difficulties, the naturalist has erected for himself an 

 aquarium, and the tanks appear to be in the highest degree satisfactory, he has the disappoint- 

 ment of learning that the light which he has been so assiduously arranging for the benefit 

 of the public is a deadly enemy to the fish. These are merely the larger troubles, and as 

 such sufficient to prove to the visitors' mind the public thanks which are due on all sides to 

 those who lend all their science, knowledge, and energy for the public good.
