ABSTRACT OF PROCEEDINGS. XXlll. 



much the same, yet, 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 eucalyptol group had refractive 

 indices ranging from 1*4686 to 1*4774 and the solubility 

 was from 1*05 to 8 volumes 70°/° alcohol, down to No. 45, 

 the remaining six being insoluble in 10 volumes. The specific 

 gravities of the oils of this group were mostly 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 pro- 

 nounced, and phellandrene absent, had refractive indices 

 ranging from 1*4801 to 1*4948, while the oils which con- 

 tained 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 contained piperitone (11 species) 

 ranged from 1*4828 to 1*4945. The 22 phellandrene oils in 

 which the sesquiterpene was a pronounced constituent had 

 refractive indices ranging from 1*4801 to 1*5065. The per- 

 fumery oils as E. citrioclora, E. Macarthuri and E. 

 Staigeriana were not classified. 



Remarks were made by Mr. W. A. Dixon, Mr. W. M. 

 Hamlet, Dr. George Harker and Mr. G. H. Knibbs. The

Mr. Lenehan exhibited a chart illustrating Trans Pacific 

 Longitude, and read a letter from Dr. Klotz in connection 

 therewith. 



Some remarks were made by Mr. Knibbs and the 

 President.
