 pick the insects which they find upon them. 



They continue in the Kamtschatkan and Ame- 

 rican seas the whole year ; but in winter they are 

 very lean., so that one may count their ribs. They 

 are taken by harpoons fastened to a strong cord ; 

 and after they are struck, it requires the force of 

 thirty men to draw then on shore. Sometimes, 

 when they are transfixed, they will lay hold of the

 hard breathing, like the snorting of a horse. 



They are of an enormous size : some are twenty-

 to the bulk of the animal, is small, oblong, and 

 almost square: the nostrils are filled with short 

 bristles : the gape or rictus is small : the lips are 

 double: near the junction of the two jaws the 

 mouth is full of white tubular bristles, which serve 

 the same purpose as the lamina? in Whales — to
