 This sea water is preferable to the natural, because it is more 

 clear'. Mons. Miable, druggist, in Favart street, sells concen- 

 trated sea water, which can be diluted at will. Mons. Gosse has 

 an aquarium of sea water, and the water has not been renewed for 

 19 months; all the fish, &c,, which die in it are of course removed 

 immediately or the rest would perish infallibly. The fresli aqua- 

 rium is more easy to manage. In point of utility these aquari- 

 ums are far more valuable for the study of pisciculture than any 

 -other thing, for here the generative, &c. of the fish can be minutely 

 examined and practical lessons gained.
