18 Report of Schimmel § Co. April/October 1917. 



Eucalyptus Oil. There were, of course, absolutely no imports of Australian euca- 

 lyptus oils, but fortunately, we were able to put at the disposal of the consumers 

 large quantities of synthetic Globulus oil, a product which, in addition to a high 

 content of eucalyptol, has all the qualities of the genuine distillate and may, in con- 

 sequence, be used as a substitute of this without any hesitation. We shall most likely be 

 in a position to continue manufacturing this welcome makeshift in sufficient quantities. 



A curious sort of eucalyptus oil was offered to us in the course of the summer. 

 A considerable quantity was supplied to us at the beginning of the war by a Hamburg 

 firm as Globulus oil, but was only utilized in part by us, so that a largish portion 

 remained over. Its strong smell of camphor oil immediately characterized this product 

 as a gross imposition, which fact was also verified by investigation, as its qualities 

 differed entirely from those of Globulus oil, viz.: di 5 o 0.8865; « D + 21°15'; insoluble in 

 70 percent, alcohol. In the case of oil from Eucalyptus Globulus the figures show 

 the following limits: di 5 o 0.910 to 0.930; « D dextrorotatory up to -j- 15°; soluble in 

 2 to 3 vols, and more of 70 per cent, alcohol. Moreover, the percentage of eucalyptol 

 in the sample was quite insufficient, since it amounted but to about 30 per cent., 

 whereas a good Globulus oil contains 80 per cent, or more. 



It is not the question of an oil of another eucalyptus species, on the contrary, 

 it is evident from the above-mentioned overpowering smell of camphor oil, in con- 

 junction with its other qualities, that the product consisted of a cineoley camphor oil 

 fraction which to the utmost may have been scented with eucalyptus oil. The Hamburg 

 firm, mentioned above, evidently imagines that for medical purposes a product may 

 be indifferently bad in quality. A point of view which is probably highly remunerative, 1 

 but implies a doubtful kind of patriotism. 



On page 56 of our October Report for 1913 we mentioned that R. T. Baker and 

 H. G. Smith came to the conclusion, as the result of their investigation of Tasmanian 

 eucalyptus species, that the Eucalyptus amygdalina which grows there is not identical 

 with the continental amygdalina species which they termed E. a. var. Australiana, although 

 by rights it ought to be given specific rank from E. a. A rectification in this concern 

 was published by the authors in their last paper on Eucalyptus Australiana, spec. nov. 

 ("Narrow-leaved Peppermint") and its volatile oil 1 ). The new species grows on the 

 ranges of New South Wales and Victoria, in a .region which has little agricultural 

 value; as this species produces a large quantity of good oil, they propose to establish 

 a permanent industry. 



One easily obtains a good product rich, in cineole on collecting the steam-distillate 

 during the first hour separately. It contains more than 70 per cent, cineole, whereas 

 the amount of cineole in the total product is only 45 percent. Besides, the first 

 fraction is nearly colourless and contains mere traces of aldehydes, so that it is 

 sufficiently pure for pharmaceutical purposes, whilst the yield is as great as that of the 

 total oil in most of the other eucalypts. The portions of the oil holding phellandrene which 

 pass over particularly in the later distillates, appear to contain an alcohol Ci Hi 8 O.

 a composite occurring in a part of the southern U. S. and found most frequently on 

 the coast, especially of Florida. G.A.Russell 2 ) has investigated the oil distilled from
