which the principal constituent was found as dimethyl ether of 

 pyrogallol. The oil freed from phenols distilled between 175 and 

 200 , and appeared to contain thujone and thujol. 



Guaiacwood Oil. After a prolonged scarcity, a large con- 

 signment of wood was at last received in February, and this enabled 

 us to execute all orders in hand. During the period of scarcity it 

 has become evident what an important part this oil plays in the 

 perfumery-trade. 



Hop Oil. According to the reports received up to the present, 

 the total result of the hop-harvest is on the average favourable. The 

 copious rainfall in the beginning of September has worked wonders, 

 especially in Bavaria, and even there a higher yield is now forthcoming 

 than was originally expected. Increases as compared with last year 

 are reported from Bohemia, Belgium, and America, whilst in England 

 about the same crop has been picked. 



The prices are lower, in agreement with the aforesaid conditions, 

 but our distillation only commences within a few days, and to-day we 

 are not yet able to quote a firm price for pure oil distilled from best 

 non-sulphured Bavarian hops. 



Jasmine "Schimmel & Co." The use of our original product 

 is constantly growing. The preference shown for it is not surprising, 

 in view of the many inferior competing products which are found on 

 the market under the same name. 



We have already mentioned previously that our product also con- 

 tains a proportion of natural oil from the blossoms, which, jointly 

 with the synthetic constituents, brings about the excellent effect of our 

 oil. It is natural that such a perfect product possesses a real value, 

 and cannot be sold at absurdly cut prices. For the rest, every con- 

 sumer or seller himself can make the product cheaper by adding 

 benzyl acetate. 



In recent extraction -experiments with fresh jasmine - blossoms 

 A. Hesse 1 ) has obtained yields of oil which were twice as large as 

 formerly. Accordingly, the enfleurage method would not give nine 

 times, but only four to five times as much oil as the extraction process. 

 At the same time, it must be assumed that a formation of essential 

 oil from some not yet isolated substances takes place during the 

 enfleurage period. Possibly the increased formation of odorous sub- 

 stances may be attributed in this as in other cases to fermentative 

 disintegration of glucosides. In the extract obtained with petroleum
