The low value of the article has lately, unfortunately, again led 
to numerous and very peculiar adulterations, such as have never been 
observed before. 
In our Report of October 1899, page 23, we mentioned already, 
that citronella oils are met with in commerce, which, although they 
are unadulterated, yet do not form a clear solution with 80 per cent, 
alcohol, and therefore do not pass Schimmel's test. But we then 
said that oils which only just formed a cloudy solution, and with which 
no oil-drops are separated out from the solution, could not be considered 
objectionable, as the insolubility could only be attributed to the re- 
sinification of the (light) sesquiterpene present in citronella oil; on 
the other hand, it should be absolutely insisted upon, that on pro- 
longed standing no small drops of mineral or fatty oil are separated 
out from the alcoholic solution, neither at the surface, nor on the 
bottom of the vessel. 
Since then we have very rarely been in a position to examine 
such insoluble, but unadulterated oils. The majority of the oils charac- 
terised by insolubility was adulterated; for this reason, we had no 
occasion to depart from the condition imposed by us, that citronella 
oil must form a clear solution even in 10 volumes 80 per cent, alcohol. 
Parry 1) has subsequently called attention to the fact, that the oils 
whose insolubility in 80 per cent, alcohol must be attributed to a high
