1 88 WHAT IS A < FEROX'? 



* la truite feroce, Trutta ferox, est une simple 

 varite de la Truite vulgaire et nullement une 

 espece particuliere.' Dr. Day, after all, our best 

 authority to this day, conies to this very distinct 

 conclusion : 



1 In fact the Great Lake Trout of Geneva is 

 the Salmo ferox of lakes in Wales, the North of 

 England, Scotland and Ireland, and merely a 

 form of our fresh-water trout.' 



It has been sufficiently shown, I would think, 

 that the so-called Salmo ferox agrees in structure 

 and in the development of the sexes with the 

 ordinary brown trout, and differs from it in 

 none of these points, the test with which we 

 set out at the beginning of this inquiry; but 

 once an error has taken root it is proverbially 

 difficult to eradicate it. And so long as it is a 

 matter of self-interest to hotel-keepers, boatmen, 

 and others to proclaim that their waters hold a 

 rare fish of great size and ferocity, just so long 

 may one expect to meet with our old friend the 

 ferox. 



Meantime it may be asserted, without fear of 

 contradiction, that the unanimous opinion of 

 modern scientific authorities is that in Great 

 Britain and Ireland we have, in all its varied 

 forms, but one species of fresh-water trout, 

 Salmo fario.
