None of the solid derivatives used to characterise many 
known sesquiterpenes could be prepared. <A liquid hydro- 
chloride was obtained by passing dry HCl gas into its 
ethereal solution (cooled with ice), and the nitrosyl 
chloride and nitrosite were also apparently liquid. ‘'The 
molecular refraction indicated probable di-cyclic character, 
and that it contained two double bonds. 
Treated with a few drops of glacial acetic acid and 
bromine vapour a violet colour was developed, rapidly 
turning deep-blue.

Summary.—The air-dried leaves of Daphnandra aroma- 
tica vielded on distillation with steam -5 per cent. of a light- 
yellow oil possessing an agreeable aromatic odour, the com- 
position of which is indicated as approximately d-pinene 
5-10 per cent., da-phellandrene 20-25 per cent., cineol 10-15 
per cent., sesquiterpene 30-40 per cent, sesquiterpene alcohol 
5-10 per cent., with minor aldehydic phenolic and ester 
constituents.
