x owe our knowledge of this important plant to one of the boldest and best of the naturalists 
employed by the French Government. Dr. Weddell, an English Botanist, attached to the mission 
of M. de Castelnau, succeeded, among innumerable difficulties, in reaching the country where the 
Calisaya, the most precious of the kinds of Cinchona, or Peruvian Barks, is produced. He 
brought seeds to Europe; and from some of them, obtained from the Jardin des Plantes of Paris
