The nch milk of Artocarpea is either poisonous, or wholesooie : it centains often an 

 abundance of caoutchouc {Mcus), or bird-lime is prepared from it {Jrtocarpus). The 

 tenacity of the fibres is remarkable in Uriiceee proper. The syncarpia, or fruits, or seeds, 

 axe eatable in several instances [Artocarpus, Madura, Brosimum). Drugs are obtained 

 from the root of Contrajerva {Sorstenia), and from the Trumpet-tree {Cecropia). The 

 Fustic-wood {Madura) contains a yellow pigment. Several West Indian Urlicacea ai'e 

 valuable timber-trees (Artocarpus, Brosimum, Pseudolmedia, Ficus laurifolia, etc.).
