234 ANTICIPATIONS OF SUCCESS. 



observation and study, even in London and other 

 inland cities ? Sucli 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

 growing in tlieir 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-

 same results by another gentleman, whose name is 

 well known in the scientific world. Mr. Robert 

 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
