 By working upon the oils of such a large number of species it was 

 possible to arrange the results in some order. The specific refractive 

 energy results cannot be used to any great extent for the purpose 

 of Classification, but if the refractive index be multiplied by 10 times 

 the solubility in 70"/,, alcohol, (sp. gr. 0-8722 at 15.5° C.) a very good 

 arrangement of the eucal3'ptol oils can be made. Those oils wich 

 contained eucalyptol in excess had, as a rule, the least refractive 

 index, and were the most soluble in alcohol. As the pinene increased 

 in amount the solubility diminished and although the refractive index 

 remained much the same, j^et, the resulting figures increased con- 

 siderably. The solubilities were taken in tenths, and the temperature 

 for all the determinations was 16° C. The oils of the 51 species in 

 the eucah^ptol group had refractive indices ranging from 1-4686 to 

 1-4774 and the solubility was from 1-05 to 8 volumes 70 "/(, alcohol, 

 dowri to N". 45, the remaining six being insoluble in 10 volumes. 

 The specific gravities of the oils of this group were mostlj' above 0-91. 

 The 7 pinene oils in which phellandrene was absent had refractive 

 indices ranging from 1-4741 to 1-4788, and none were soluble in less 

 than 7 volumes 80 "/^ alcohol. The pinene oils (14 species) in which 

 the sesquiterpene was pronounced, and phellandrene absent, had 

 refractive indices ranging from 1-4801 to 1-4948, while the oils which 

 contained the aldehyde aromadendral in some quantity, and in which 

 phellandrene was absent (9 species) had refractive indices from 1-4828 

 to 1-4946. The refractive indices of the phellandrene oils which con- 

 tained piperitone (11 species) ranged from 1-4828 to 1-4945. The 22 

 phellandrene oils in which the sesquiterpene was a pronounced con- 

 stituent had refractive indices ranging from 1-4801 to 1-5065. The 

 perfumery oils as E. citriodora , E. inncarthitri and E. Staigeriana 

 were not classified. Autorreferat.
