or needles of Abies pectinata or even, as in the case under review, to a mixture. But 
when a person expressly demands a definitely specified oil and receives the same of 
unimpeachable quality, it is somewhat humorous to find him reject it as inferior. 
Where such a state of things prevails it is no wonder that traders of a certain class 
exploit the conditions to the utmost of their power. 
Some years ago we mentioned a paper by J. W. Brandel and M. Sweet’) on Douglas 
fir needle oil. We are now again in a position to report on this oil, A. W. Schorger”) 
having found oil of the needles of the Douglas fir (yield about 0,163 p.c.) to contain 
the following constituents: 25 p.c. /-e-pinene (nitrolpiperidide), 48 p. c. /-6-pinene (nopinic 
acid), 6 p.c. 7- or /-limonene (hydrochloride; tetrabromide), traces of furfurol (colour- 
reaction with aniline hydrochloride), 6,5 p.c. borneol (oxidation into camphor), 6,1 p.c. 
esters, calculated as bornyl acetate (the acetic acid was identified from the analysis 
of its silver salt) and 3 p.c. of a green-coloured fraction, b. p. 125 to 205° (20 mm.) 
apparently containing sesquiterpene. No camphene was present in the oil, whereas 
Brandel and Sweet had been able to detect this terpene in the product examined by them. 
The constants of the two distillates also show somewhat considerable points of 
difference. Schorger found his oil to possess the following characters: dis. 0,8727 to 
0,8759, @p»0 — 17,02 to — 22,172, npiso 1,4758 to 1,4780, acid v. 0,65 to 1,1; ester v. 11,13 
to 24,25, ester v. after acet. 27,5 to 51,78. Brandel and Sweet record the following 
properties: ds30 0,8680, «~)— 62,5°, acid v. 0, sap. 86,6. These differences may perhaps 
be explained by the fact that the distillate described by Brandel and Sweet had been 
prepared in the State of Washington, and the oil examined by Schorger in California. 
Rasamala Oil’). From the resin of Canarium microcarpum, Willd. (N. O. Burseracee), 
which had been received from the Moluccas, 80,4 p.c. of oil has been distilled at

| Rose Oil, Anatolian. With reference to Anatolian rose oil, it is reported that 
pretty considerable quantities of rose oil are manufactured in the neighbourhood of 
Isbarta (Sparta, Asia Minor), the quantity produced in the year 1912 having been 300, 
and in 1913 as much as 400 kilos®). Formerly all this oil was sold to Bulgaria, and 
exported thence as Bulgarian rose oil. Last year, however, the oil was bought up by 
a firm in Smyrna and shipped direct to Europe. It is said that the farmers of Isbarta 
are still ignorant of the methods of adulterating the oil, and that therefore the oil 
supplied by them is quite pure. The characters of the oil are as follows: d= 0,850, 
py — 3°30’, npos0 1,4605, m. p. 24 to 25°. ; 7 
Rose Oil, Bulgarian. The firmness in the position of the market to which we 
referred in our last Report has been, generally speaking, maintained throughout the 
winter, but of course only for quality which was beyond reproach, for so-called “pure 
qualities” were, as always, plentifully offered on the market, and could be had at all 
sorts of prices. In November sales were made at about 3700.— /fes., a price which 
places the cheap quotations of the middlemen in their proper light. Naturally, at this
