288 FISHES OF THE FIRTH OF FORTH. 



William Jardine, that an angler, whilst fishing in the Tweed, 

 hooked a Salmon that carried away his tackle ; after put- 

 ting on a new set, baited as before with a worm, in ten mi- 

 nutes after he hooked and killed the same fish with the for- 

 mer hook in its mouth. This, adds Mr Yarrell, will either 

 prove extreme voracity, or little sensibility in the parts of 

 the mouth. 



Salmon, as food, are in the best season from March till 

 August, after which the generality of them become pale in 

 the flesh, soft, and very unwholesome. 



There is occasionally taken in the Firth of Forth, a small 

 species of Salmon, or rather a variety, which is said to oc- 

 cur more frequently in some of the large rivers further 

 north, where it is commonly known by the name of Nor- 

 way Salmon. Plate XXXII. Fig. 2. It is seldom found to 

 exceed the length of two feet, and much resembles the com- 

 mon Salmon in miniature. The characters agree in every re- 

 spect with those I have given of Salmo salar, excepting that 

 it is of much smaller size ; the dorsal fin rather nearer the head 

 than to the base of the tail ; the pectorals and ventrals 

 rounded at the end ; the fifth, sixth, and seventh rays being- 

 longer in proportion ; the pectoral, dorsal, and caudal fins, 

 dark grey, instead of dusky black; twenty scales in an 

 oblique row between the dorsal fin and the lateral line, and 

 the flesh is not so red or so well flavoured as that of the 

 Salmo salar. Number of fin rays —
