 This is the dulse of the Scotch, wlio are very fond of it in the 

 fresh and crude state. Liglitfoot says, however, that they prefer 

 it dried and rolled up, when they chew it like tobacco, for the 

 pleasure arising from the habit. This is the "saccharine fucus," 

 or sol, of the Icelanders, the efflorescence of which has a sweetish 

 and not disagreeable taste. It is di'ied by the natives, packed 

 down in casks, and used as occasion requires, frequently cooked 

 with butter. Cattle, sheep in j^articular, often eat this species 

 with eagerness, whence it has been called Fucus ovinus. Crypt.
