are often similarly useful. Sissoo wood is that of the Indian species 

 of this genus, of the same specific name. Senegal ebony is D. melan- 

 oxglon. 1 A large number of hard coloured woods, very incorruptible, 

 from tropical America are produced by Dalbergia or the neighbouring 

 genera Vatairea, Centrolobium, Cgclolobium, Tipuana, Macluerium, &c, 

 though, it is impossible to refer each kind to its producing genus. 

 This is the case with the true Palissandre wood, or violet-ebony, and 

 probably the so-called Saint-Martin and Prefontaine woods of Guiana. 

 In India the Dalbergia-r yield good woods, especially D. latifolia, 

 heterop/tglla, and ferruginea ; but it is hardly possible to refer each 

 commercial kind to its proper species. Centrolobium tomentosum 

 Benth., of Guiana, is also mentioned for the value of its wood. The 

 Gaiac of Guiana is not Guaiacum sanctum (of the order Zggop//gllacea) 

 but Coumarouna odorata, 3 the Tonquin-bean Tree ; its hardness makes 

 it difficult to work. The members of LoncJiocarpus often attain a 

 great height. The wood of L. sericeus from tropical America and 

 Asia, resembles that of the Lemon-tree. The u Cceur-dehors " (heart 

 outside) of Guiana, in which interlacing fibres form a heartwood 

 and alburnum of equal strength, is Diplotropis guianensis Benth. ; 

 the Boco is Bocoa provacensis. 4 The Carn-woods are produced by 

 several African Bap/iias. 5 The Panacocco* are due some to American 

 species of Ormosia or Baracaras, with a hard blackish heartwood ; 

 others to Tounatea or Swartzia (figs. 201, 202), of which several are 

 used in building, while some furnish arcabas ; these are the thin 

 projecting ribs removed from the trunk and termed bois-pagage, on 

 account of certain of their uses. The Immortelle or Brythrina wood 

 is of a weak spongy consistency, as also in certain Sesbanias and 

 notably in the species of JEschgnomene, such as JE. aspera. 1 In this 

 aquatic species the stem becomes cellular and spongy, and very 

 light ; it is hence used to make light head-dresses, children's toys,
