Hab.—Brazil. Extraction.—The tuberous root consists princi-pally of starch and a white, milky, poisonous is rasped and pressed to separate the juice, whichdeposits a fecula; this, when washed, and dried inthe air without heat, is termed Moussache (frommouchaco, a Spanish word, signifying boy or lad), orCip/pa, and for some years past has been importedinto France from Martinique, and sold as arrow-root.(Guibourt, Hist, des Drog. t. ii. p. 466, 3m« ed.) Ibelieve it to be identical with the Brazilian Arrow-root of English commerce. When this fecula hasbeen prepared by drying on hot plates, it acquires agranular character, and is then termed Tapioca. The compressed pulp is dried in chimneys, ex-posed to the smoke, and afterwards powdered. Inthis state it constitutes Cassava powder, or Farine de Manioc. If it be granu-lated by agitating it in a heated iron pan until incipient tumefaction
