always be had in any quantity, and possibly may be supplied some 

 time even much cheaper than at present quoted, is a sufficient 

 guarantee that prices of cassia oil, such as ruled towards the end of 

 the nineties, need not be feared again. 



Oil of Champaca-blossoms. After many fruitless and expensive 

 attempts, we have at last succeeded in discovering a reliable source 

 of supply of this oil which for a long time we had been compelled 

 to omit from our lists. We expect shortly the arrival of several kilos, 

 so that the scientific examination of this oil can now also be taken 

 in hand. 



The properties of the oil of the first consignment were: diso 0,8 86 1; 

 « D — i^io'; acid no. 10,0; ester no. 21,6; ester no. after acetyl- 

 ation 150,1; soluble in 2 vol. 70 per cent, alcohol; when 4 vol. and 

 more are added, strong turbidity; soluble in 1 vol. and more 80 per 

 cent, alcohol, when more than 7 vol. are added, opalescence (separation 

 of paraffin). The oil has a bright brown colour and shows, especially 

 in alcoholic solution, a very feeble blueish fluorescence, which may 

 possibly be due to the presence of anthranilic acid ester. Of alcohols, 

 linalool appears to be present in the oil, but owing to the small 

 quantities of oil at our disposal, we were unable to obtain an exact 

 proof of this. 



Cinnamon Oil, Japan. K. Keimatsu 1 ), in examining the 

 essential oils from the leaves, trunks and roots of Cinnamomum 

 LoureiriiNees, growing in the Japanese province Ki-i, found the following 

 constituents. In the oil from the leaves: as principal constituent 

 citral, and small quantities of eugenol; in the oil from the trunks: 

 as principal constituent cinnamic aldehyde, and also small quantities 

 of eugenol; in the oil from the roots: as principal constituent cin- 

 namic aldehyde, and further camphene, cineol, and linalool. — These 

 results agree with those of our own earlier examinations 2 ), made with 

 the oil from the twigs and leaves of the Japanese cinnamon or cassia 

 bark tree, C. Loureirii Nees. We described the oil at the time as oil 

 of nikkei. 



Citronella Oil. The position of this important article can be 

 judged only with difficulty, as reports on the conditions in the producing 

 districts have lately been very scarce, and one has chiefly to depend 

 on conjectures. It may be taken as a fact that all the oil shipped 

 before the bursting of the monsoon, i. e. in October and No- 

 vember, will be absorbed by existing contracts; the unimportant quan-
