We have already repeatedly referred to the excellent anthelmintic 

 action of American wormseed oil 1 ). A recently published communication 

 by H. Bruning 2 ) discusses the question of the therapy of helminthiasis 

 in the tropics. The author is of opinion that American wormseed oil is 

 far superior to all other anthelmintics. Eucalyptus oil Bruning regards 

 as possessing very little efficacy, and the results which have been ob- 

 tained from the use of eucalyptus oil and chloroform are ascribed by 

 him principally to the action of the last-named drug 3 ). The results of 

 the experiments with eucalyptus oil which have been made at the instance 

 of Prof. Kobert demonstrate that this oil, like cineol, only possesses slight 

 anthelmintic properties 4 ). 



Wormwood Oil. Owing to the disappointing result of the crop in 

 1910, the price of American oil had already been run up to $ 6. — p. lb., 

 and the speculators who, in the course of the autumn, had succeeded 

 in buying up everything, were successful in raising the quotations to 

 $6,75 and $7. — . During the last few months the article has remained at 

 this figure, but on the European market the demand has only been slacks 

 German wormwood oil being available in sufficient quantities. The ex- 

 quisite distillate of wormwood grown in our fields at Miltitz in particular 

 has been in very brisk demand, all reports agreeing that it cannot be sur- 

 passed for excellence and purity of aroma. French wormwood oil has 

 practically disappeared from commerce, but Italy produces occasional 

 small quantities of an oil which more or less corresponds to the French 

 article. 



According to our New York friends there is every reason for believ- 

 ing that the coming season will see the wormwood acreage increased con- 

 siderably, yet on account of the weakened condition of many of the old 

 fields which failed to produce the looked -for crop in 1910, and also for 

 reason of small stock held over, they fail to see any cheap wormwood 

 in view for 1911. 



Ylang'Ylang Oil. In spite of the excess of cheap ylang-ylang oils, 

 the popularity of our "Sartorius" brand has remained undiminished, and 

 notwithstanding plentiful arrivals the demand was correspondingly animated. 

 There have lately been strong complaints in Manila that since the Ameri- 

 cans have taken possession of the Philippines the cost of manufacturing 

 is growing higher and higher, and that at the same time the profit on the 

 distillation is decreasing at a truly alarming rate. How serious a thing 

 this is may be judged if we take into consideration that production in 

 Reunion, to the growth of which we have already repeatedly called attention
