instances of the addition of alcohol have been observed, but many- 

 cases of adding geraniol and similar bodies which alter the physical 

 constants only very slightly, but which betray themselves by the 

 increase in the geraniol content. Five such sophisticated samples, 

 which had been sold as "guaranteed pure oil", contained from 79,5 

 and 82 °/ of total alcohol, whereas pure rose oils contain not over 75 °/ . 

 Hence Parry, in common with ourselves 1 ), regards the determination 

 of the total geraniol content as a most important factor in judging the 

 value of a rose oil. 



We ourselves recently handled a Bulgarian rose oil which was 

 sophisticated with both adulterants at the same time. The original 

 sample only behaved a little abnormally as regards the index of re- 

 fraction, but the indications of adulteration were apparent as soon as 

 the oil had been extracted with water. The sp. gr. at 30 was thereby 

 increased from 0,8606 to 0,8632, the index of refraction from 1,46565 

 to 1,46674 and the congealing point from -}- 20 to-j-2i°. We 

 were able, by fractional distillation, to isolate from the water of ex- 

 traction about io°/ of alcohol (calculated for 90 per cent, alcohol). 

 The sp. gr. which was suspiciously high for rose oil, and the index 

 of refraction, which was much too high, in conjunction with the ab- 

 normal geraniol -content which, even after removal of the alcohol, kept 

 at 7°\5%> P omt to the conclusion that palmarosa oil as well as alcohol 

 had been added.
