of a value of £ 72. The preparation of the oil has now been taken up 

 by a business-house. The parent plant, according to a determination made % 

 at the London Botanical Gardens, is Cymbopogon citratus, which accounts 

 for the imperfect solubility of the oil. 



We have previously described a lemongrass oil from Uganda (Report 

 April 1909, 65).

Brooks 1 ) describes the oil of an as yet unknown Andropogon-species 

 which is evidently closely allied to lemongrass oil. The constants of the 

 oil were as follow: dfj§ 0,8777, « + 0, n D30 o 1,4868, and it contained about 

 72% citral (m. p. of the semicarbazone 155 to 160°) and 12% geraniol. 

 The latter was isolated by means of the calcium chloride compound. 



Limette Oil. We have recently received from our well-tried, reliable 

 source of supply fresh shipments of the finest hand-pressed oil, so that 

 up to the present we have been able to satisfy the requirements of the 

 numerous customers who have been attracted in the course of years by 

 our exquisite quality. Unfortunately the shipments have been less plentiful 

 of late, and we have therefore already been compelled to increase our 

 prices. The demand for our terpeneless limette oil has also been very 

 animated. 



Oil of Limnophila. According to Brooks 2 ) the leaves of a species 

 of Limnophila (N. O. Scrophulariacese), which occurs in the Philippines, 

 yield about 0,2% of an oil with a rosemary-like odour and a density 

 of 0,850. 



Linaloe Oil. The market in Mexican linaloe oil has been greatly 

 neglected throughout the winter months, but in spite of this there has 

 been no decline in prices worth mentioning. The main reason for th^ 

 great neglect of the article must no doubt be sought in the competition 

 of the exquisite Cayenne linaloe oil, which was obtainable at remarkably 

 cheap rates and of which the quality is far superior to that of the Mexican
