DULSE — CARRAGEEN. 



On plate k, fig. 3, may be seen a specimen of 

 the Plocamium of the natural size, and near 

 it a single branch magnified, in order to show 

 the tiny combs. 



Many of the marine algse are used as articles 

 of food; some eaten uncooked, and others after 

 a long course of boiling. To the former of these 

 categories belongs the Dulse, Dillisk, or Dillosk 

 {Ehodymenia palmata)^ although it is sometimes 

 cooked. The species, however, which is here 

 illustrated, is Rliodymenia hijlda, a plant of a 

 very fine rosy red when fresh, found in tolerable 

 profusion adhering to rocks or on the larger algae. 

 The fronds are generally two inches or so in 

 length, and about a quarter of an inch in width. 

 For a figure of this plant, see plate k, fig. 4. 



The Carrageen Moss, so well known in the 

 form of jelly and size, is one of the Ehodosperm 

 Algse, by name Chondrus crispus. (Plate J, 

 fig. 5.) 



It may be found growing on the rocks in large 

 quantities, where its shape will be the best guide 

 to its detection, for its colour is exceedingly 

 variable. Although one of the Ehodosperms, it 

 is very frequently of a greenish tint, and in many 

 places it assumes a yellow jaundiced complexion, 

 not at all of a healthy nature.
