338 Marine Algce of Berwick-on-Tweed. 



f. sobolifera (Fl. Dan.) J. Ag., Spec. Alg. 



Sab. On rocks and Algae. Not uncommon. 



Dr. Johnston quotes from Ray: " Hunc Hiberni Scotique 

 apud quos copiose invenitur, studiose exsiccatum et convolutum 

 assidue in ore habent et masticant." Adding "The less agree- 

 able tobacco has supplanted this use of dulse, which, however, 

 in a raw state, is still occasionally eaten by the common people, 

 from a belief of its being a sweetener of the blood, and a remedy 

 for scorbutic complaints." With us, little or no dulse is now 

 eaten, and it does not seem at all probable that its use will ever 

 again become popular, for to most persons its taste is anything 

 but agreeable. In Jamieson's Scottish Dictionary, I find the 

 following derivation of the word "Dulse," the Gaelic form of 

 which is " Duillisg," a word said to be " compounded of Duille 

 a leaf and uisge water ; literally the ' leaf of the water.' "
