because several shipments which have arrived for us were not equal to 

 the conditions of purchase in respect to quality. Moreover, our New York 

 branch inform us that one of their contractors, from whom they had purchased 

 a parcel for December/January shipment, was^quite unable to give delivery, 

 and has found himself compelled to come to an arrangement with our 

 friends. Hence the important reduction in price which we were able to 

 make in our February quotations has only been of short duration. On 

 the other hand it is probable that, in Germany at any rate, the demand 

 for cassia oil will undergo some restriction, because in the 5 th edition of 

 the German Pharmacopoeia this oil has been superseded by Ceylon cin- 

 namon oil. 



Chamomile oil. The various parcels of raw material which have 

 been worked up by us in course of the winter gave on an average a 

 very unsatisfactory yield of oil, and we have therefore been compelled to 

 make a not inconsiderable advance in the prices of our distillate. It is 

 to be hoped that our supplies will hold out until the new crop. 



Champaca Oil. Bacon 1 ) is of opinion that our statements relating to 

 champaca oil 2 ) (from Michelia Champaca, L.) cannot have reference to pure 

 distillates. So far as his experience goes it is not possible at Manila to buy 

 20 cwts. of yellow champaca flowers at a time. Bacon therefore regards it as 

 probable that the oil on which we reported consisted of distillates of mixtures 

 of champaca flowers and other flowers. For instance, he suspects that 

 the oil referred to by us in the year 1897 consisted of a distillate of a 

 mixture of champaca and ylang-ylang flowers, on account both of its 

 ylang-ylang odour as well as because of the presence in it of benzoic acid, 

 for Bacon has not found that acid to occur in champaca flowers distilled 

 by himself. We had already stated on a previous occasion that cham- 

 paca flower oil was not a uniform distillate. Thus, for instance, a Javan- 

 ese oil had been distilled, as stated by a manufacturer, from a mixture 

 of flowers of Michelia longifolia and of Michelia Champaca 2 ). 



The author examined an oil which had been distilled from yellow 

 champaca flowers {Michelia Champaca, L.), the oil-yield being 0,2%. When 

 the oil was allowed to stand, a considerable proportion of crystals sepa- 

 rated out from it. 



After being freed from crystals and left to stand for a long time, 

 the oil became semi-solid, as the result of the separation from it of 

 an amorphous mass (probably resinified oil), and when 70% alcohol was 

 added this resinous mass was recovered in the form of a brown, odourless 

 body. After filtering, the liquid portion was evaporated in vacuo at 40° 

 until a brown oil had separated out, which possessed an exquisite
