7 . Note F. : 
Linneus, in his Flora Laponica, tells us that the roots of 
Calla palustris, although acrid and caustic in the highest degree, 
(Cignis firme instar, are made into a kind of bread in high esti- 
mation, called Missebred. This is performed by drying and 
grinding the roots, afterwards boiling and macerating them un- 
til they are deprived of acrimony, when they are baked like other . 
farinaceous substances into bread. 
The recent juice of the Jatropha manihot, or Cassava tree of 
the West Indies, is highly poisonous. The deleterious princi- 
ple however resides in a volatile portion, which is dissipated by 
heat. The remaining substance of the root is used by the in- 
habitants for bread, as a material for a kind of soup, and as the 
basis of a fermented liquor.
