several drugs, furnishes the Essence of Lemon by pressure or distil- 

 lation. Its acid pulp is used in making a refreshing drink, and as 

 a topical, exciting, antiputrid, haemostatic drug ; and from it also are 

 extracted the citric acid used in commerce and medicine, The 

 number of varieties and forms of the preceding species, more or less 

 commonly used in industry and domestic economy, is also con- 

 siderable. 1 



The properties of Amyris 2 more nearly approach those of JBurse- 

 racece, to which this genus was long ascribed. 3 They are fragrant 

 and balsamic, and are said to yield some resinous products. A. syl- 

 vatica 4 of the Antilles, is an aromatic and stimulant plant. In the 

 same regions, A. balsamifera? whose fragrance is very balsamic, is 

 considered venomous. The production of a kind of elemi is attri- 

 buted to A. Phcmieri f and Hamilton names his A. kexandrdJ as 

 furnishing the gum elemi of Nevis. 8 The wood of several species ot* 

 Amyris is useful. That of A. sylvatica is the JBois de Citron (Lemon 

 wood) of commerce. Its qualities are thus very similar to those of 

 the beautiful wood of the Auraniece? so much used in fine cabinet 

 work, especially that of the Citron ; and also to that of the Lemon, 

 which is close, scentless, pale yellow, and susceptible of being turned 

 and polished like box, but is less beautiful than the latter ; to that of 

 the Seville Orange, tolerably hard, and of a greyish-white ; and to 

 that of the true Orange, which is white, without veins, and sometimes 

 coloured red towards the centre. The wood of Quassia and Picrcena 

 employed as bitters, as we have seen, are susceptible of a fine 

 polish, and may be used in cabinet work, although rather light. That 

 of Quassia is a yellowish-white ; the other is yellower, more fibrous, 

 and less satin-like. These two woods are not attacked by insects, 10 and
