Cinchona for quinine production. While ultimately successful in their primary aim, these expeditions also identified new species of plants and created a new chapter in international relations between the United States and other nations in the Americas. Francesco Torti used the response of fevers to treatment with cinchona as a system of classification of fevers or a means for diagnosis. The use of cinchona in the effective treatment of malaria brought an end to treatment by bloodletting and long-held ideas of humorism from Galen. For his part in obtaining and helping the establishment of cinchona in British India Clements Markham was
Tree fork forms in a tree and bark is incorporated into the join, this is referred to as an 'included bark junction' or 'bark inclusion'. A common cause of bark being incorporated into the junction is that the junction is braced by the touching of branches or stems set above that junction (in arboriculture, these branch interactions are termed 'natural braces'). Such included bark junctions can be substantially weaker in strength than normal tree forks, and can become a significant hazard in a tree, particularly when the bracing branches are shaded out or pruned out of the tree. Research has shown that
