caoutchoucn.

/ˈkaʊtʃʊk/

/ˈkuːtʃʊk/

Etymology: < French caoutchouc /kautʃu/, < Carib cahuchu (Littré).

a. India-rubber, or Gum Elastic; the milky resinous juice of certain trees in South America, the East Indies, and elsewhere, which coagulates on exposure to the air, and becomes highly elastic, and is waterproof; it is now a most important substance in arts and manufactures.‘Introduced to France early in the last [i.e. 18th] century, but its origin was unknown till the visit of the French academicians to South America in 1735. They ascertained that it was the inspissated juice of a Brazilian tree, called by the natives Hhvé; and an account of the discovery was sent to the academy by M. de la Condamine in 1736’ ( Penny Cycl.). Chiefly obtained from the Brazilian Siphonia elastica ( Hevea caoutchouc) family Euphorbiaceæ, and East Indian Ficus elastica. But many other tropical plants, Euphorbiaceæ, Apocynaceæ, Artocarpads, and others, yield it in considerable quantity. Chemically it is composed entirely of carbon and hydrogen, but is not a simple proximate principle, but a mixture of substances.
