60 THE PROTEACEiE OF AUSTRALIA. 



Banksia Australis is especially instanced in yielding as 100 parts 

 of its wood, 29'5 of charcoal, 40-062 of crude wood vinegar, 6-562 

 of tar, and 23-876 of uncondensible gases, while Banksia serrata 

 gave 10-8 per cent of tannic acid. The drupaceous fruits of the 

 Proteacem are for the most part small and insipid, but Macadamia 

 teruifolia, or the Queensland nut, bears an edible nut of excellent 

 flavour, whilst the flowers of Banksia ornata, Lambertia formosa, 

 and some other species are rich in melligenous sap.
