With regard to the influence of prolonged storage on elemi resin, 

 Clover states that the limonene of the resin remains unchanged, but 

 that the terpinene and phellandrene undergo far-reaching changes. The 

 dry distillation of the resin yielded, in addition to 5 to i o °/ water, about 

 70% malodorous resin oils which passed over between 170 and 350 . 



Oil of Canarium Cumingii Engl. Under the name "Pag- 

 sainguin oil" we received from the Bureau of Science of Manila 

 an oil obtained from the resin of Canarium Cumingii Engl. , which 

 was mobile, pale green, almost colourless, and showed the following 

 constants: di 5 o 0,8627; a D-f-ii 3'; n r>20° M7 2 45; soluble in 3 and 

 more vol. 90 per cent, alcohol. On distillation the oil passed over 

 from 158 to 183 ; the bulk (7o°/ ) boiled between 165 and 177 . 

 The principal constituent of the oil appears to be cymene. 



Essential Oils, Sicilian and Calabrian. 



Our old friend, Mr. Eduardo Jacob at Messina, has agaiu 

 assisted us most kindly with his Report, which we reproduce in extenso 

 hereunder: — 



In my Spring Report I was already able to state that the export 

 of the essential oils of this place, during the first three months of 

 this year, showed a large increase as compared with the same period 

 of the previous year. This increase has made further progress during 

 the following five months, and even the exceptionally high prices of 

 the last two months have not led to a falling off in the export to 

 any marked degree, as is always the case during those months. 



It is interesting to compare the figures of the current year with 

 those of the three previous years. The export was: —

The export during these 8 months of the present year con- 

 sequently exceeds not only that of the corresponding period of the 

 two last years, but also of 1904.
