The production of anise oil, and particularly of anethol, represents 
now as before one of the specialities of our firm. In our new factories, 
we have provided plant for this purpose which enables us to satisfy 
in every respect the highest requirements. 
We would state here, that the idea of producing and introducing 
into commerce pure anethol on a large scale, has first been realised 
and rendered an accomplished fact by our firm, and for this reason 
we are fully justified in calling our anethol "the original product". 
Our anethol possesses the characteristics of the greatest purity which 
it is possible to attain: — 
Congealing point: -\-2i to 22^, 
Melting point: -[-22,5 to 22,7°. 
Although we ourselves also work up considerable quantities of 
Russian anise oil into anethol, it would be wholly incorrect to call this 
kind of anethol the best in existence, as is done in a most provoking 
manner by a Russian competitor. There are some kinds of anise and 
raw materials for anethol, which should be preferred to the Russian 
seed. The consumers may be quite satisfied that there is a large 
selection of material, for if we were exclusively dependent on the 
Russian production, the value of the article would undoubtedly be 
considerably higher. 
In our April Report of this year, we already referred to the fact 
that an anethol is offered in commerce at a higher price, which is 
praised as being richer than any other anethol. We had an oppor- 
tunity of testing such a product, but its physical constants as ascertained 
■did not by any means point to special purity. 
We also came in possession of a circular in Spanish, mentioning,- 
as a criterion of the purity of anethol, a congealing point of 22 to 
23°; all preparations melting at a lower temperature are declared to 
contain elaeoptene, and to be useless for the manufacture of anisette 
liquor. If, in accordance with this, a selection were to be made 
of the various commercial anethols, not a single one would be found 
to possess the necessary qualification, for not one of them would show 
a congealing point of 22 to 23°, not even (as we have ascertained) the 
one produced by the firm who issued this circular ! 
We have always found the congealing point of freshly prepared 
anethol at more than 21°, up to 22°, but the melting point, on the 
other hand, at from 22,5° to 22,7°. Although really the melting and 
congealing points should lie at the same degree of temperature, the 
congealing point will generally be found a little lower than the melting 
point, as a slight delay in the occurrence of the crystallisation, or 
a reduction of the temperature below th^ solidifying point carried a little 
too far, must of necessity lead to errors in observation. On these
