is 0.940 : its boiling point is 380 the mercury ultimately rising 

 to 420: the taste is aromatic, and cooling, with but little pun- 

 gency, it has a fragrant camphoraceous odor, and an oily con- 

 sistency. In a lamp it gives a good bright clear flame, but 

 somewhat inferior to kerosene in intensity. It is a good solvent 

 for a variety of resinous bodies. 



11. Eucalyptus rostrata, Schlechtendal The Red Gumtree 

 (but not of West Australia) This variety has a wider range 

 than any other of the Australian timber trees, being found in 

 West Australia, South Australia, Victoria, New South Wales, 

 Queensland, North and Central Australia. 



Compared with the afore mentioned, the yield of oil from 

 this species is small, 100 Ibs of fresh leaves furnishing 1.56 

 fluid ounce. It has a similar taste and smell to that from E. 

 odorata: color pale yellow with occasionally a reddish amber 

 tint : specific gravity 0.918 : the boiling point is lower than 

 that of any of the others, being 280, the mercury afterwards 

 becoming stationary at 358. Evaporated to about one-fourth 

 its bulk, it almost geletinises when reduced to zero, retaining its 

 transparency. In the lamp this oil burns well. It is a good 

 solvent for a variety of resinous bodies. 



12. Eucalyptus viminalis : Labillardiere The Manna Eu- 

 calypt found in South Australia, Victoria, New South Wales 

 and Tasmania a middle sized tree. 



The yield of oil from this species is small, the amount from 

 100 Ibs of fresh leaves being 0.65 fluid ounces. The color of 

 this oil is pale yellowish-green : the odor disagreeable, but not 

 very strong or penetrating: its taste is similar to that of >. 

 odorata. It has a spcific gravity of 0.921 : it boils at 318 

 the mercury subsequently rising to 360. It burns well in a 

 lamp and is a good solvent for a variety of resinous bodies. 



13. Eucalyptus citriodora, Hooker the Citron-scented Gum 

 a tree found in the North of New South Wales and the South 

 of Queensland. It yields a fair amount of oil, which forms a 

 superb cosmetic.
