in any quantity, a very important article In medicine. Some of this 

 class, as the AJuria r\rulcnta of (ireat Britain, will also bo found edi- 

 ble, and mucilaginous, like Chondnu crisptu. Oar FWngj have been 

 as yet very imperfectly investigated, but it is well known that we have 

 a considerable number that are wholesome and edible ; while a still 

 larger number are prisonous ; and we have no means of distinguish- 

 ing them, except actual experience. Griffith states that the same spe- 

 cies may be wholesome or poisonous, according to circumstances. The 

 secale cornutum deserves mention, as an important agent in the list of 

 our materia medica ; as do also some of our lichens, possessing both 

 alimentary and medicinal properties. It will probably be found that 

 we have some not far inferior in these respects to the Cetraria islan- 

 dica, (Iceland Moss,) or the Gyrophora proboscidia, (Tripe de Roche,) 

 of the artic regions. These still remain to be investigated, and furnish 

 a wide field for the cultivators of this department of Medical science.
