NATURALIZATION OF FISH. 259 



has become Protestant, the cultivation of 

 fresh water fish has been much neglected. 

 The burbot, or lotte, which already exists 

 in some of the streams tributary to the 

 Trent, and which is a most admirable fish, 

 might be diffused without much difficulty; 

 and nothing could be more easy than to 

 naturalize the spiegil carpfen and siluris ; 

 and I see no reason why the perca lucio 

 perca and zingil should not succeed in some 

 of our clear lakes and ponds, which abound 

 in coarse fish. The new Zoological Society, 

 I hope, will attempt something of this kind; 

 and it will be a better object than intro- 

 ducing birds and beasts of prey though I 

 have no objection to any sources of rational 

 amusement or philosophical curiosity. But 

 the time for our parting is almost arrived. 

 Let us drink a glass each of this old wine 

 of the Danube to our next happy meeting, 

 and go and take a last look at the Fall of 

 Traun whilst our carriages are preparing.
