56 Volatile Oils. 



E. Fabrorum, or Stringy Bark. 



Yields a transparent reddish-yellow oil, milder in odour 

 than those of the last type, in flavour resembling carraways 

 and smoke essence combined, less pungent, but distinctly 

 bitter. Yield from 100 lbs. fresh leaves was 8 ozs. 



E. Fissilis, or Messmate. 



In all respects like the last. 



These two are powerful solvents, though not equal to the 

 Globulus type. 



E. Coryrabosa, or Bloodwood. 



The material from this species had suffered from close 

 packing and length of time in transit, Dr. Mueller having 

 obtained it for me from East Gipps Land. The yield from 

 100 lbs. of leaves was 9 ozs. 3 drs. of pure limpid oil, 6 ozs. 



2 drs. of oil containing resinous matter in suspension. Sup- 

 posing one half of this latter part of the yield to consist of 

 resinous matter, the net amount of oil from 100 lbs. will be 

 12 j ozs. This oil possesses an agreeable perfume of a rose 

 and lemon flavour, its taste is slightly bitter, but not so 

 pungent and diffusible as others. Sp. gr, 0'881. The E. 

 Corymbosa forms a type. 



E. Woolsii, or Wooliybutt. 



Also from East Gipps Land. The oil is clear and colour- 

 less, much resembling an expressed oil, and possesses the 

 remarkable property of imparting an indelible stain to paper, 

 indicating that some peculiar substance is held by it in 

 solution. Its sp. gr. bears out this supposition, being 0-94:0. 

 Its taste is camphoraceous and aromatic, its odour like that 

 of the melaleuca oils. Yield from 100 lbs. of leaves, 3 ozs. 



3 drs. 



E. Amygdalina, or Dandenong Peppermint. 



Yields an astonishing amount of oil. From 100 lbs. of 

 fresh leaves and branchlets I obtained three Imperial pints 

 of oil, and this result was confirmed by repeated experiments. 

 It is of a pale yellow colour, of a mild and cooling taste, and 

 has the predominating camphoraceous odour, which last, 

 however, disappears as the oil advances in age. Sp. grav. 

 - 881. Its solvent power is great, but not equal to the 

 Globulus type. This species I attach to the E. Odorata 

 type. 



We proceed to the oil-producing species of the Melaleuca 

 genus. 



These species are not so abundant as the Eucalypti, but 

 are sufficiently so to deserve consideration.
