ctjy — o° io'; aldehyde-content about 82°/ ; insoluble in 10 vol. 70 percent, 

 alcohol; soluble in 0,9 vol. 80 per cent, alcohol, when more solvent is 

 added soon strong turbidity; with 90 per cent, alcohol it forms at first 

 a clear solution, but when more than 1,5 vol. are added, cloudiness 

 occurs. According to these results the oil behaves like the West Indian 

 and African lemongrass oils, which we have repeatedly referred to in 

 our Reports 1 ). Owing to the deficient solubility, the oil has a lower 

 commercial value than the ordinary East Indian lemongrass oil. 



Oil of Leptospermum Liversidgei. Several years ago we 

 reported already on the oil of a species of Leptospermum, viz., Lepto- 

 spermum scoparium, according to researches by C. E. Atkinson 2 ). We 

 have now before us a work by R. T. Baker and H. G. Smith 3 ) on 

 the oil of Leptospermum Liversidgei (called after A. Liversidge, Pro- 

 fessor at the Sydney University). The crude oil was insoluble in 10 vol. 

 70 per cent, alcohol, soluble in 1 vol. of 80 per cent: diso 0,8895; 

 a v-\-9, 2 °', n Di6° 1,4493- At 170 2O°/ of the oil distilled (di 5 o 0,8624; 

 a D + 32,5°; n Di6° i,4774), between 195 and 225 30% (d 15 o 0,8892; 

 a D~f~5»7°; n Di6° 1,4892). The principal constituents of the oil are citral 

 (35,o°/ ; naphthocinchoninic acid, m.p. 199 ), recognisable by its charac- 

 teristic odour; further, geraniol (9,74°/ ), slightly covered by the odour 

 of citral; geranyl acetate (5,35%)? anc ^ d-pinene (25%; nitroso- 

 chloride, m. p. 103 ), and finally, in addition to one which could not 

 be determined, a sesquiterpene (24,91%; d^o 0,9024; n Di6o !,505 2 )- 

 Limonene and phellandrene were not detected. 



Linaloe Oil. The value of this important perfume has since 

 the spring gradually risen to 17 marks per kilo, and the Hamburg 

 importers, who have practically monopolised now for some considerable 

 time the trade in this article, appear little inclined to concessions, 

 although there are numerous indications that the European market has 

 laid in an abundant supply in good time. Cheaper offers from second- 

 hand are not rare. The report recently spread, that several factories 

 for the rational distillation of linaloe oil had been established in Mexico, 

 does not appear to find confirmation; on the contrary, it is said that 

 the production is still carried on by Indians by means of portable and 

 very primitive apparatus. We are informed that the firmer tendency 

 of the market during the last few months is not at all due to lack 

 of oil, but must be attributed simply to successful operations of the 

 Mexican exporters.
