consumers have recourse to our German wormwood oil, which is being 

 distilled at Miltitz on a large scale. Our fields have yielded several 

 cuttings of exquisite quality, and all consumers who desire to use really 

 first class wormwood oil are urgently advised to submit our product to a 

 practical test. 



Ylang - Ylang Oil. Since the manufacturers of our favourite brand 

 "Sartorius" have met the consumers by a reduction in prices, this im- 

 portant oil has again excited the greatest interest, and we are unable to 

 accumulate any stocks of it. The superiority of this, the finest quality 

 of all ylang-ylang oils, is best shown by the fact that in spite of all the 

 cheap competing oils it not only maintains its position, but has recently 

 even found increased preference. The over-production in Reunion, to which 

 we have already so often called attention, still continues. The exports 

 from that island were as follows: — 



1907 523 kilos 



1908 1126 „ 



1909 1792 „ 



that is to say, within 3 years they have more than trebled, while at the same 

 time the average price has receded from fr. 500 to fr. 300 per kilo. 



In the first half-year of 1910 alone the exports amounted to 1560 kilos, 

 from which it appears that for the current year also a considerable increase 

 in shipments is to be expected. If we take into consideration that the 

 distillation of ylang-ylang oil has lately also been taken up on a considerable 

 scale in the Comoro Islands, and that the conditions of production 

 there are said to be still much more favourable than in Reunion, the most 

 thorough-going optimist will have to admit that the future is not a rosy 

 one for the manufacturers. 



According to Roure-Bertrand Fils x ), an ylang-ylang oil from the Island 

 Mayotte (Comoros) behaved as follows: di 5 o 0,9324, « D — 47° 40', acid 

 no. 1,0, sap. no. 113,4 = 39,7°/o ester, calculated for linalyl acetate, ester 

 no. after acetyl. 134,4, soluble in its own vol. of 90°/o alcohol, the solution 

 rapidly becoming opalescent when more alcohol was added. 



The above constants fall within the limits recorded by Bacon 2 ) for 

 Manila ylang-ylang oil.
