THE ODOUR OF ROSE. 31 
Report of the English Consul at Constantinople states that the 
Otto industry of Turkey suffers from the effect of the mistrust 
naturally aroused by the admitted wholesale adulteration of the 
product with geranium oil. It is therefore highly probable that 
the efforts made to grow the rose in the north of Europe, and 
prepare the otto with the most complete technical appliances, will 
shortly succeed to a great extent in competing with the Turkish 
product, especially as the firms who are now making these efforts 
are of a standing and respectability which guarantee the purity of 
their products. Certainly, with a little more sunlight and heat, 
they would entirely supersede the Turkish manufacturers. At 
the Paris Exhibition of 1878 a sample of about 3 oz. of pure otto 
of rose was exhibited by M. Hanart of Auzin, Département du 
Nord, as being the produce of about 24 ewt. of rose-petals grown 
in the Auzin district. 
In about 1886 a rose plantation was established near Leipzig 
by Messrs. Schimmel and Co. of that city. In their Report for 
April 1891, they state that these rose-fields extend over about 180 
Prussian acres, the oil from which is introduced into commerce in 
a liquid state, 7. e. practically free from stereoptene, which has 
been mechanically extracted from it. Such oil will therefore 
remain liquid at ordinary temperatures, will readily dissolve in 
spirit, and, used in the preparation of compound bouquets, will 
not deposit stereoptene. (A very great advantage to perfumers.) 
Undoubtedly a reliable product of this sort, which must have cost 
much material sacrifice and perseverance to establish, will be duly 
appreciated and supported by the buyers, but it remains to be 
seen whether this otto will compete in fragrance with that distilled 
in the south of France, where the rose culture has attained an 
enormous development. The French oil has a greater consistence 
than the Turkish, and is more green in colour. At Grasse 8000 
to 10,000 kilos of rose-petals yield about 1 kilo of oil. It is 
collected as a by-product in the distillation of rose-water. It 
does not appear that this oil has been offered for sale “ sine 
stereoptene.” 
In contrast with the rough distillatory apparatus in use in 
Bulgaria, the annexed woodcut illustrates the more rational system 
of using steam-jacketed stills in France, and represents the actual 
view of a still-room in the factory of Messrs. Sozio and Andrioli 
at Grasse.
