(». Eucnh/ptm fon/mbosa, Smith — the Rloodwood tree — found 

 ill Victoria, Now South Wales, and Queenshiud— a rather hirge 

 •tree. Unfortunately these leaves had suffered somewhat from 

 ■fermentation, and in conse({uence it is only possible to give thi; 

 approximate yield : and this was for 100 lbs. of leaves 12.')l» 

 iiuid ounces. 



The oil is a colorless and limpid fluid ; in odor it differs from 

 all the other Eucalypti oiis ; so much so indeed that it could 

 scarcely be recognized as of Eucalyptine origin. Its smell, com- 

 pared with the others, is much fainter and milder, and whilst 

 partaking slightly of the lemon odor of that of the L\ ami/gda- 

 ■fti"i, combined with a trace of attar of rose, it wants altogether 

 tne charactonstic pungency and freshness of its congeners. The 

 taste is slightly bitter, producing the usual after-taste of pepper- 

 mint, and irritating the throat ; but it is not so diffusible and 

 l)ungent as many others. The specific gravity is 0.H81. In the 

 lamp it burns with a flame rather more luminous tlian that from 

 American kerosene, but somewhat yellow. It is a good solvent 

 for a variety of resinous bodies. 



7. EiicaJj/ptiDi oblif^iui., 'L'Heritier — the Stringybark tree — 

 found in Victoria, South Australia, New South Wales, and Tas- 

 mania. In Victoria alone, the area almost exclusively wooded 

 with the stringybark tree extends over many thousand S(juare 

 miles. The height of the trees of greatest size ranges from 800 

 to 400 feet. 



With regard to the yield of oil, 100 lbs. of freshly gatlu-red 

 leaves afford 8 fluid ounces. It is a transparent reddish-yellow 

 fluid of a mild odor, as compared with that of A\ gonlocdlj/x and 

 E. glolndm, and much less disagreeable. In taste it resembles 

 the other Eucalyptine oils, but is rather more irritating in the 

 mouth, and also distinctly bitter though less unpleasant. Tlu; 

 i'pecific gravity of this oil is 0.899 ; the boiling point is ?Ai)''\ 

 the mercury afterwards rising to SSS'^ ; cooled to (P F. it be- 

 ijomes turbid and opalescent. In the lamp it burns with a fine 

 flame, not quite so white,, however, as that from E. gnnioai/i/.r 

 and E. globulus. It is a .>;ood solvent for a variety of resinous 

 hodies.
