I leave these facts to speak for themselves. They arc better 

 than a thousand theories. Here is one vessel of water made 

 from my formula eight mouths ago ; hei'C is another made four 

 months ago. iSeither has at any time been changed, nor even 

 shifted ; the waste of evaporation has been merely supplied from 

 time to time with fresh [i. e. river) water. Both of them have 

 always maintained marine animals and vegetables in health, from 

 the first until now; and both contain animals that have sur- 

 vived for the whole period. Finally, both have preserved their 

 purity and transparency. 



I shall be but too happy to show any scientific persons the 

 vessels in question, and to give any information in my power. 

 I am. Gentlemen, your obedient servant, 



P. H. GossE. 

 58, Huntingdon Street, Bamsbury Park, 

 December 20th, 1854. 



P.S. Some letters which have been lately published by Mr. 

 W. A. Lloyd in the ' Athenseum ' confirm my experience. Perhaps 

 I may be excused for citing a few words contained in a private 

 letter from the same gentleman to myself : — 



" In reference to what has recently been published on an im- 

 provement (or a supposed improvement) on your receipt for the 

 manufacture of sea water, a friend of 'mine took me by the button 

 and said, ' My dear Sir, Mr. Gosse is altogether wrong ; he has 



not salt enough ; he has no .' To which I replied, pointing 



to two fine Actinia dianthus in full blow in one of my vessels, — 

 ' But if Mr. Gosse is altogether wi'ong, why do these Actinia 

 flourish ? ' This was unanswerable."
