EUCALYPTUS LONGDFOLIA. 



bark of different Eucalypts is very variable, as may be noted from experiments, instituted tinder 

 my directions by Mr. L. Rummel, fresh bark being used for the purpose, the tannic principle 

 loosing its solubility and also its efficiency to some extent by exsiccation and chemical decom- 

 position.
