 in the oil of the Braid wood variety more potent than phellan- 

 drene, possibly the oxidation products of the unknown alcohol. 



The OH of E. Smithii. — This oil contains over 70% of cineol.

This is another case in which we have the rectified oil having 

 a stronger disinfecting action than the crude. It is not quite so 

 pronounced as with E. cinerea, but there is less room for the 

 formation of substances of an aldehydic nature; the saponifica-
