The Catalonian monks prepare an extract of the Cortex angosturae which they send to the convents of their province, and which deserves to be better known in the north of Europe. It is to be hoped that the febrifuge and anti-dysenteric bark of the bonplandia will continue to be employed, notwithstanding the introduction of another, described by the name of False Angostura bark, and often confounded with the former. This false Angostura, or Angostura pseudo-ferruginea, comes, it is said, from the Brucea antidysenterica; it acts powerfully on the nerves, produces violent attacks of tetanus, and contains, according to the experiments of Pelletier and Caventon, a peculiar alkaline substance* analogous to morphine and strychnine. (* Brucine. M. Pelletier has wisely avoided using the word angosturine, because it might indicate a substance taken from the real Cortex angosturae, or Bonplandia trifoliata. (Annales de Chimie volume 12 page 117.) We saw at Peru the barks of two new species of weinmannia and wintera mixed with those of cinchona; a mixture less dangerous, but still injurious, on account of the superabundance of tannin and acrid matter contained in the false cascarilla.) As the tree which yields the real Cortex angosturae does not grow in great abundance, it is to be wished that plantations of it were formed. The Catalonian monks are well fitted to spread this kind of cultivation; they are more economical, industrious, and active than the other missionaries. They have already established tan-yards and cotton-spinning in a few villages; and if they suffer the Indians henceforth to enjoy the fruit of their labours, they will find great resources in the native population. Concentered on a small space of land, these monks have the consciousness of their political importance, and have from time to time resisted the civil authority, and that of their bishop. The governors who reside at Angostura have struggled against them with very unequal success, according as the ministry of Madrid showed a complaisant deference for the ecclesiastical hierarchy, or sought to limit its power. In 1768 Don Manuel Centurion carried off twenty thousand head of cattle from the missionaries, in order to distribute them among the indigent inhabitants. This liberality, exerted in a manner not very legal, produced very serious consequences. The governor was disgraced on the complaint of the Catalonian monks though he had considerably extended the territory of the missions toward the south, and founded the Villa de Barceloneta, above the confluence of the Carony with the Rio Paragua, and the Ciudad de Guirior, near the union of the Rio Paragua and the Paraguamusi. From that period the civil administration has carefully avoided all intervention in the affairs of the Capuchins, whose opulence has been exaggerated like that of the Jesuits of Paraguay.
