The non-iiii'jiatory Imbil ol ihe lurgf lacusiiinr si)irios does 

 not depend, in any dejjree, on their position or sitnation above 

 inipa-ssahle eataraets, or in waters withont outlets, although 

 they are tVetpiently found under sueh eireiunstanees, tor they 

 do nut run ilown to the sea, even wliiii tiny ha\i' it in their

 ficial, from the sea; and, although these teem with hordes of 

 Hroitk Tn)Ut, they never attain, in them, to any si/.e ; the 

 mature adidts being scarcely larger than the young fry, while 

 they are still marked with the transverse bandings of the Parr. 

 The tlesh of this little fish never attains the rich clurry-coloured 

 tint of the Trout, in full season, but is of a pale yellowish tlesh- 

 colour, nnd has neither the richncHS nor the Havour of the sen-
