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

 class, as the Alaria esculenta of Great Britain, will also be found edi. 

 ble, and mucilaginous, like Chondrm crispus. Our Fungi 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 poisonous ; 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. The^e still remain to be investigated, and furnish 

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