130 SALMONIA. 



Hal. — I have opened ten or twelve, and 

 never found any thing in their stomachs but 

 tape-worms, bred there, and some yellow fluid; 

 but, I believe, this is generally owing to their 

 being caught at the time of migration, when 

 they are travelling from the sea upwards, and 

 do not willingly load themselves with food. 

 Their digestion appears to be very quick, and 

 their habits seem to show, that after having 

 taken a bait in the river they do not usually 

 seek another, till the work of digestion is 

 nearly performed : but when they are taken 

 at sea, and in rivers in the winter, food, I am 

 told, is sometimes found in their stomachs. 

 The sea trout is a much more voracious 

 fish, and, like the land trout, is not willingly 

 found with an empty stomach. 



Phys. — I presume the sea trout is the fish 

 called by Linnaeus, in his Fauna, SalmoEriox? 



Hal. — I know not : but I should rather 

 think that fish a variety of the common salmon. 



Phys. — But there are surely other species of 

 salmon, that live in the sea and come into our 

 rivers : I have heard of fish called grays^ hull 

 trmt, scurfs^ morts, peales, and wkitlings.
