It is” still desirable, bor purposes ° of examination, to know the melting points of 
‘the various extracts, and we will later on extend the investigation in this direction. 
__ We mentioned above that we have had no satisfactory experiences lately with 
the civet on the market, and of the examined samples will only mention those, which 
show in a specially remarkable manner, the unheard-of methods employed by some 
in adulteration, and to show the necessity of a thorough examination even for this 
article. A well- known Parisian firm sent us one sample of civet described as garantie 
pure, whilst the other two offered us for sale came from Cologne and London respectively. 
It turned out that the Parisian and Cologne goods contained considerable quantities - 
of vaseline, whilst about half of the London sample consisted of talc. These additions — 
naturally had a very strong influence of the result. of the analysis, as a comparison 
of the following Stn. with the above limiting values will show.

The ether extract was considerably raised by the vaseline (civet I and II), whilst 
on the other hand their ester value and sap. value were lowered. The lowerings of 
the acid value, ester value and sap. value of the alcoholic extract is also noteworthy, 
which shows that a small quantity of vaseline is also taken. up even on extracting with 
alcohol. Apparently more vaseline has gone into solution in the case of II than in I, 
é from which it is explainable that in I the alcohol extract is greater and its acidvalue, 
ester value and sap. value smaller than in I. The addition of vaseline has, moreover, 
lowered the residue and the water content of both. From the quantities of the ether 
- extracts one can assume that the vaseline content of lI amounted to at least 30 per cent., 
_ and of II to at least 25 per cent. The wee was also recognisable by the blue 
fluorescence of the solution. © ; 
The admixture of talc in IMI soma its presence in a different way. The first 
thing that strikes one is the tremendous increase in the residue, which goes hand 
- in hand with a lowering of the alcohol- and ether-extract, as well as that of the 
_ water content. The incineration of the residue showed that it was mostly inorganic 
' and consisted almost wholly of talc, the amount of which came to over 45 per cent.
