Essential Oils, Sicilian and Calabrian. 
Mr. Eduardo Jacob, German Consul at Messina, has this year, with 
his usual courtesy, again kindly supplied us with the following report, 
for which we beg to express to him, also in this place, our most 
sincere thanks. 
The report shows that the export of essential oils of last year 
has fallen behind that of the previous year by 220557 kilos or 
3229599 lire, i. e. by about 20 ^/q (see tables on pages 43 and 44). 
This is readily explained by the abnormally high export figures 
of 1902, and further by the fact that the summer, both in the Old 
World and in the New, has been very cold and rainy, and therefore 
very unfavourable for the consumption of lemon oil. At the same 
time, it should be noted that the demand from abroad, in spite of 
the heavy export of 1086497 kilos in the year 1902, during the 
year under review accounts for no less than 864940 kilos, i. e., the 
largest quantity exported during any of the last 10 years — with the 
exception of the year 1902. 
A more convincing proof of the constantly increasing world -con- 
sumption of Sicilian essential oils can scarcely be produced; and the 
same is confirmed by the comparative figures of the last five years, 
and of the five years immediately preceding. Whereas during the 
period 1894 to 1898 an average annual export of 626876 kilos or 
8540731 lire has taken place, the figures for the period 1899 to 
1903 have grown to an average of 870162 kilos or 12234757 lire, 
and the exports during the months December, January and February 
of the present year again show an increase as compared with those 
of the same months of the previous season, as will be seen from the 
following summary: — 
1902 December 73440 kilos 1903 December 83356 kilos 
1903 January 95 975 1904 January 105877 „ 
1903 February 97646 „ 1904 February 98897 „ 
By far the largest share of the increase in the exports naturally 
falls to the article lemon oil. 
The physico-chemical constants of the various citrus oils during 
this season have shown no variations worth mentioning; oil of bitter 
orange alone has from first to last shown an exceptionally low rot- 
atory power. The majority of the oils has not exceeded the rotation 
of 89°, and parcels with a higher rotatory power are quite exceptional.
