.state. Benzoyl-a-dihydroterpenylamine has m. p. 219°, and when ozonised 

 ^yields 2-benzoylamino-l-methylc^cfohexanone-4 and acetone, which fact 



elucidates the constitution of dihydroterpenylamine. Benzoyl-/?-dihydro- 



terpenylamine melts between 178° und 179°. 



Benzoyldihyrocarvylamine, when treated with ozone, is converted into 



l-methyl-2-benzoylamino-4-ethanoylci/cZohexane.
