Sample I had a pronounced odour of pine tar oil, whereas the other sample 
showed great similarity with certain fractions of wood turpentine oil. Whether 
ester of the two oils was really bornyl acetate is more than questionable in view of th 
_ result of the analysis; at any rate the sample smelling like pine tar oil smelled nary j 
of bornyl acetate, and in the other sample the ester appeared to consist of fenchi isa ig 
-acetate which closely resembles bornyl acetate in smell. The samples at our t disposal — 
were, unfortunately, too small to permit of closer investigation. re 7 
We avail ourselves of thi8 opportunity to report on an adulterated oil of Pinte 
Pumilio supplied by a French firm, and.submitted to us by the buyer in Sinaia 
Its properties were as follows: diso 0.8779, a) +-5° 36’, acid value 0.6, ester value 3.7, — 
soluble in about 6 vol. and more of 90 per cent. alcohol, with but slight turbidity. a 
The adulteration was easily recognized by the dextrorotation, for oil of Pinus Pumilio 
turns the light to the left (a —4°30’ to —99°, in isolated cases up to — 15° 20’); 
moreover the specific gravity was too high and ester value too low. To judge from 
the odour we had to deal with a mixture of oil of Pinus Pumilio with camphor oil 
and turpentine oil. Lt ee 
These samples may sound a note of warning to buyers, for they show that in these 
days even such oils are supplied in doubtful qualities in which formerly adulteranon: ; a 
was the exception, rather than the rule. 
In an article on oil of Pinus sylvestris which appeared in the Phasohenentiicne Weng a 
a short description is given of the process of distillation of the needles or cones of 
pines and firs in Sweden, Germany, Switzerland, the Tyrol and the United States. @ 
Though the report deals with points which are mostly well-known, we me here state Sy 
that some of the informations given are not quite correct. ; x

Oil of Rose, Bulgarian and Anatolian, We need hardly lay stress on the ee iS 
that the War has made the task of reporting exceedingly difficult. From news to hand 
we gather that this year’s distillation was at first carried out under very favourable 
conditions in the rose districts in Bulgaria, later on however a well-nigh tropical heat — 
set in which considerably affected the yield of oil. We are informed by a reliable 
source that the average yield was 1 kilo of oil from 3500 kilos of blossoms, the total — 
result of the crop being 2800 kilos of rose oil. The considerable. drop, as compared 
with 3888 kilos in 1915, failed however to exert an appreciable influence on the price 
which generally speaking remained unaltered at its previous level of about Z 1000.— 
per kilo for irreproachable qualities. As a matter of fact, in consequence of the w 
the balance of the crops from 1913 to 1915 was still unsold and as export. is in 
large measure paralyzed an improvement in. price is not to be fone’ of ee
