and durable perfumes. Such, in the true sense of the word, is our 
distillate, especially if it is compared, with regard to its richness, with 
the imported commercial oils from Reunion and the East Indies. 
Genvresse and Langlois^) discovered in vetiver oil a sesqui- 
terpene of the boiling point 262 to 263^, at 740 mm, which did not 
completely agree with any of the hitherto-known sesquiterpenes. The 
oil also contained an ester of the boiling point 160° at 10 mm, 
which on saponification yielded an alcohol of the formula C^5 Hgg O, 
and an acid 0^51^2404. 
Wintergreen Oil. Higher prices for genuine oil are reported 
from America. In consequence of important contracts we still supph' 
the oil, until further notice, at a moderate price. 
Cosma^) recommends artificial oil of wintergreen for internal 
administration in rheumatism and various kinds of neuralgia. The 
results obtained with it are said to be much superior to those obtained 
with sodium salicylate. The daily dose may be up to 8 grams. Up 
to now the ester was used almost exclusively as an embrocation. 
Wormwood Oil. In a few weeks' time we expect to have 
again an excellent assortment of this oil, and also a stock of the 
American distillate, but the prices will be comparatively high. The 
fine French wormwood oil of this year's distillation, also produced 
from the cultivated herb, is alread}^ on the wry. Algiers also supplies 
a product well worthy of attention. 
In spite of the fact that in France the use of wormwood oil for 
articles of consumption is now prohibited, fairly large quantities are still 
consumed in other countries. The prohibition is exclusively directed 
against the increasing use of absinth, but no objections have as yet 
been raised against the employment of very small doses of the oil, 
such as for example in the preparation of wormwood-wine. 
Ylang-Ylang Oil (artificial) ^^Schimmel & Co". The in- 
creased demand for fine natural oils has also greatly promoted the 
use of our beautiful artificial product, whose quality constantly finds 
the greatest appreciation. 
This case proves once more, that both the natural and the artificial 
oil are qualified to exist alongside one another, without the one 
affecting the consumption of the other. The creation of cheap and
