Hab. Abundant on all the rocky shores. 



Four to six inches to afoot high, of a livid purplish colour. This is the 

 Dulse of the Scotch, who are very fond of it in a fresh and crude 

 state. Lightfoot says, however, that they prefer it dried and rolled 

 up, when they chew it like tobacco for the pleasure arising from the 

 habit. Tills is tlie saccharine Fucus of the Icelanders, the efflores- 

 cence of which has a sweetish and not disagreeable taste. It is 

 dried by the natives, packed down in casks, and used as occasion 

 requires, frequently cooked with butter. Cattle, sheep in particu- 

 lar, often eat this species with eagerness, whence it has been called 

 Fucus ovimis.
