354 LXIX. ACEEINE^. 



comtined with a resinous matter and a certain quantity of volatile oil. The berries of several species and 

 the aril of others have an agreeahle taste, ovping to the mucilage, sugar, and free acids vrhich they con- 

 tain ; while others possess narcotic principles which render them eminently poisonous. The seeds of most 

 yield a fixed oil by expression. The bark, root, and pulp of the fruit of the Soap Tree {Snplndm Saponarid) 

 are regarded as tonics; besides which, this pulp, like that of its Asiatic congeners, froths with hot water 

 like soap, and is used in washing, being said to cleanse more linen than sixty times its weight of soap. 

 The berries of jS'. seneyalmsis are sought by the negros for their sugary and vinous taste. The succulent 

 and well-tasted aril of Melicocca serves as food in Asia and America, as well as that of the Akee {Blighia 

 or Cupania sapida), an African plant cultivated over the tropics of both worlds. The fruit, cooked with 

 sugar and cinnamon, is taken for dysentery, and when roasted is applied to indolent tumours. The species 

 of the genus Nephelmm rank high among Asiatic fruits; N. Litchi (Litchi), N. Longanum (Longan), N. 

 lappaceum (Eambutan), and their congeners, are cultivated for their excellent fruits, which are used in 

 inflammatory and bilious fevers. The Serjanice and the Paulliniee, American genera, are poisonous ; the 

 Brazilians use their juice to stupefy fish ; and it is from the flower of Serjania lethalis that the Lecheu- 

 quana bee collects a narcotic-aci-id honey, of which a small quantity produces raving madness, and even 

 death. The juice of Paullinia Cururu is used by the savages of Guiana to poison their arrows ; the negro 

 slaves prepare a poison with the root and seeds of P. pinnata ; the expressed juice of its leaves furnishes 

 the Brazilian Indians with a powerful vulnerary. The seed of P. sorbilis is bitter and astringent ; the 

 Brazilians powder it, and make it into a paste called gum-ana bread, which they roll into little balls or 

 cylinders; on their journeys they dilute this dried paste with sugared water, when it forms a refreshing 

 and febrifuge drink. [It owes its properties to a principle, guaranene, identical with theine. — Ed. J Cardio- 

 spa-mum Halicacahum, a herb growing throughout the tropics, produces a mucous nauseous root to which 

 aperient and lithontriptic virtues are attributed, [but its leaves are cooked as a vegetable in the Moluccas. 

 — Ed.]. Dodoncsa owes its scent to a resinous principle which exudes from its leaves and capsules; the 

 leaves of D. viscosa are used for baths and fomentations ; its seeds are edible. [The Mamheh and Choopa 

 of Malacca, species of Pierardia, and the Tampui (Hedycarpus malayanus) yield esculent drupes ; these 

 genera, hitherto regarded as Euphorbiaceous, have recently been referred to Sapindaceee. The seeds of 

 the wild Prune of South Africa (Pappea) abound in oil. Many produce most valuable timber, and the 

 structure of the wood of many climbing species is most remarkable. The African Teak {Oldjieldia 

 africana), doubtfully placed in EuphorbiacecB, is referred to Sapindanea by T. Mueller. The wood or 

 Pteroxylon utile, of South Africa, is hard, and as handsome as Mahogany ; its sawdust causes sneezing, 

 whence the Oape names of Neishout and Sneezewood. Hippodromus alata, of the same country, also 

 yields a valuable timber. — Ed.]
