6. Eucalyptus corymbosa, Smith the Blood wood tree found 

 In Victoria, New South Wales, and Queensland a rather large 

 tree. Unfortunately these leaves had suffered somewhat from 

 fermentation, and in consequence it is only possible to give the 

 approximate yield : and this was for 100 Ibs. of leaves 12.50 

 fluid ounces. 



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

 all the other Eucalypti oils ; 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 E. amygda- 

 lina, combined with a trace of attar of rose, it wants altogether 

 the characteristic pungency and freshness of its congeners. The 

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

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

 pungent as many others. The specific gravity is 0.881. In the 

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

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

 for a variety of resinous bodies. 



7. Eucalyptus obliqua, [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 square 

 miles. The height of the trees of greatest size ranges from 300 

 to 400 feet. 



With regard to the yield of oil, 100 Ibs. of freshly gathered 

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

 fluid of a mild odor, as compared with that of E. goniocalyx and 

 E. globulus, and much less disagreeable. In t iste it resemble-; 

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

 mouth, and also distinctly bitter though less unpleasant. The 

 specific gravity of this oil is 0.899 ; the boiling point is 340, 

 the mercury afterwards rising to 382 a ; cooled to Q F. it be- 

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

 flame, not quite so white, however, as that from E. goniocalyx, 

 and E. globuhis. It is a good solvent for a variety of resinous 

 bodies. 



8. Eucalyptus fissiUs, Ferd. Mueller the Messmate tree. 

 This tree occurs under the same condition* as E. oblijun. The
