 Persoonia Guareoides, Willd. spec. 331. The inhabitants of 

 Guiana extract an oil from the seeds of this tree by boiling 

 them in water, which they call oil of carapa, and is used by them 

 for rubbing their hair and all parts of their body ; it preserves 

 them against the bites of insects and the humidity of the atmos- 

 phere. This oil is thick and bitter. The trunk of the tree fur- 

 nishes masts for small vessels. The tree is called Carapa by
