 lust case, viz. S fluid ounces from 100 lbs. ol' freshly <;atliere(i 

 leaves. This oil has a ]i:ile re(klis}i-_vH»>w color, and a rather 

 7nild and ai:reeable odor, in which respects it resembles the oil 

 I'rom K. ohlitjiid. Its taste likewise is very similar, like it, at- 

 tiiekin^' the throat. Its specilic gravity is 0.1)03: it boils at 

 1550°, the temperature rising till it reaches HHG". In a lamj) it 

 burns with a finnie rather less luminous than that IVoui Ameiican

 common with those li'oin other species ol' Euealypis, is a good 

 solvent i'or a variety ()t'resinou> liodies.
