In continuation of the work outlined in this paper, it is 

 proposed to investigate various other aspects of this method 

 of halogenohydrination. Some possible applications of the 

 reaction in synthetic and other organic chemical processes 

 are worthy of consideration, particularly, it would seem t 

 in connection with the preparation of synthetic drugs. The 

 use of ethylene bromohydrin in the novocaine synthesis is 

 a case in point; further, the grouping :C(OH)0(NHR): , 

 so readily derived from the closely related halogenohydrin 

 grouping, :0(OH)C(X):, appears to possess a considerable 

 degree of physiological importance. In conclusion, it may 

 be remarked that the presence of so many ethylenic con- 

 stituents in the Australian natural essential oils lends an 

 additional interest to the reaction.
