MIGRATION. 87 



caught on the Atlantic side so early as on the east coast of 

 Scotland ; and the various times of their approaching the 

 coasts in the Baltic prove the fixity of their places of 

 resort. 



4. No well-authenticated instance has been given of 

 the herrings having been seen approaching the south in 

 a high northern latitude. Indeed, although we have con- 

 versed with intelligent masters of the Dutch herring- 

 busses, we could not find any one who ever saw any 

 considerable shoal on the northern part of their fishing- 

 grounds ; and none of the seamen of our Greenland whale 

 ships ever saw any of those shoals of the magnitude so 

 fabulously described proceeding southwards ; and Scoresby 

 made the same statement to ourselves, — namely, that he 

 liad not, in his many voyages, ever seen any shoals of her- 

 rings proceeding southwards. 



5. No shoals of herrings have ever been ascertained to 

 exist in the Greenland seas, and no herrings have ever 

 been found in the stomachs of the whales caught there. 

 The food of the Balcena mysticetus, or common whale, 

 consists of Actinias, Sepise, Medusoe, Cancri, and Helices. 

 The Narival inhabits the seas near Spitzbergen, but re- 

 mains of Sepise only were found in the stomachs of several 

 examined by Scoresby. The Trichecus rosmarus (Walrus 

 or Sea-horse) inhabits the icy seas adjacent to Spitz- 

 bergen ; in the stomachs of those examined only shrimps 

 {Grangon vulgaris), craw-fish (Palinurus vulgaris), and 

 young seals (Phocce) were found. Of other marine 

 animals examined by him, Scoresby says the Alca arc- 

 tica (Auk or Puffin) feeds principally on shrimps and a 

 small species of helix ; of the Alca alva (Little Auk), 

 that it also feeds on shrimps ; of the Colymbus Oylde 

 (Guillimot), it feeds on shrimps and small fishes; of the
