POIET. — You spoke just uov. r of the gillaroo trout 

 as belonging only to Ireland. I can, however, hardly 



Gillaroo — Loch Melvin. 



bring myself to believe, that such a fish is not to be 

 found elsewhere. Tor lakes with shell-fish and charr 

 are common in various parts of Europe, and as the 

 gillaroo trout is congenerous, it ought to exist both 

 in Scotland and the Alpine countries. 



HAL. — It is not possible from analogies of this 

 kind to draw certain inferences. Subterraneous 

 cavities and subterranean waters are common in 

 various countries, yet the Proteus Anguinus is only 

 found in two places in Carniola — at Adelsburg and 



draining, but not to deep thorough draining, the tendency of which is 

 the reverse, similar to that of peat mosses, and perhaps even in a 

 higher degree. The constant stream of water that flows from land 

 thus drained, even in a period of drought, is proof of the influence 

 adverted to. — J. D.]
