 Society of Edinburgh. 



" This fish is considered by most writers on British Ich- 

 thyology to be identical with Salmo fario, the Common

* James Stuart Menteath, Esq. of Closeburn, caught a number of small river 

 Trout, and transferred them to a lake (Loch Ettrick) where they grew rapidly ;

 short time of a deep red, while their external appearance remained the same from 

 the time they were first put in.
