234 ANTICIPATIONS OF SUCCESS. 



observation and study, even in London and other 

 inland cities ? Such a degree of success as I have 

 attained would admit of so desirable a consummation, 

 for even in London no great difficulty would be expe- 

 rienced in having a jar of sea-water brought up once 

 in a couple of months. I hope to see the lovely 

 marine Algae too, that hitherto have been almost 

 unknown except pressed between the leaves of a book, 

 growing in their native health and beauty, and wav- 

 ing their delicate translucent fronds, on the tables of 

 our drawing-rooms and on the shelves of our con- 

 servatories. 



It is a curious circumstance that experiments 

 exactly parallel to these, founded on the same prin- 

 ciples, have been simultaneously prosecuted with the 

 same results by another gentleman, whose name is 

 well known in the scientific world. Mr. Kobert 

 Warington of Apothecaries' Hall has now (Dec. 1852) 

 at his residence in London a marine aquarium, with 

 living Algae and Sea-anemones in a healthy condition. 

 I find, on comparing notes, that Mr. Warington has 

 precedence of me in instituting these experiments; 

 but the particulars that I have above detailed of my 

 own success were fully recorded before I had the 

 slightest knowledge that the thought of such a project 

 had ever crossed the mind of any person but myself.

Highly curious are the needle-like crystals or spi- 

 culae of flint or lime that enter into the composition of 

 many of our Sponges ; and I would hardly wish to
