OILS. 271 
This oil much resembles 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 high specific gravity bears out this supposition. (Bosisto.)’

18. Eucalyptus maculata, Wook. f.,(Syn. £. vartegata, F.v.M.; £. 
peltata, Benth.); N.O., Myrtacez, B.FI., iii., 254 and 258. 
‘“* Spotted Gum.”’ 
The fresh leaves yield, on distillation, a neutral oil of specific 
gravity 0.891. (Staiger.) 
Port Jackson, northward, to Central Queensland. 
19. Eucalyptus maculata, Hook. /, var. citriodora, N.O., Myr- 
face, B.FI., iii., 257. 
‘Lemon, or Citron-scented Gum.” (For synonyms, see “ Timbers.’’) 
The dry leaves yield a neutral essential oil of specific gravity 
.892. (Staiger.) It possesses the remarkably delicious odour of 
the leaves. (See 2. Bazleyana.)

“ Tallow-wood,” or ‘‘ Turpentine.” (For other vernacular names, see 
* Timbers.”} 
The fresh leaves of this tree yield 1.960 per cent. (other 
figures give 3750zS. to one ton of leaves) of an essential oil of an 
acid reaction, and a specific gravity of .896. (Staiger.) This oil 
has not a very agreeable odour (see remarks under £. Bazleyana), 
but it probably might be found useful in varnish-making. 
Dr. Bancroft points out that the oil distilled from the young 
leaves is of finer quality and more fragrant than that from the 
mature foliage, which remark is probably true of most Eucalypts.
