COMMON SALMON. 45 



up the sum ^ 10400. Now in consequence the 

 produce must defray all, and no less than twenty 

 times the sum of fish will effect it, so that 208000 

 Salmon must be caught there one year with an- 

 other." 



The general length of the Salmon is from two 

 and a half to three feet, but sometimes much 

 more * : the male is principally distinguished by 

 the curvature of the jaws ; both the upper and 

 lower mandible bending towards each other more 

 or less in different individuals, and at different sea- 

 sons. The general colour of both sexes is a silvery 

 grey, of a much darker cast on the back : the sides 

 of the male are marked with numerous, small, irre- 

 gular, dusky and copper-coloured spots, while those 

 of the female exhibit only several rather large, di- 

 stant, roundish, or somewhat lunated spots of a 

 dark colour. Exclusive of these differences, the 

 male is of a somewhat longer or more slender shape 

 than the female : the scales in the Salmon are 

 middle-sized, and not very strongly adherent. 



In the intestinal canal of the Salmon is often 

 found a species of Tsenia or tape-worm of about 

 three feet in length. Di\ Bioch informs us that in 

 a Salmon which had been three weeks dead, he 

 found one of these worms still living. 



* It is said to be sometimes found of the length of six feet. 

 Mr. Pennant mentions one of seventy-four pounds weight as the 

 largest he ever heard pf.
