Mandarin Oil. As already mentioned in my last report, mandarin 

 oil has only been produced in small quantities this year. As the existing 

 stocks were gradually used up, the article began slowly to improve in 

 price, and this firmness is the more likely to endure because the pro- 

 spects of the new crop, so far as they can be estimated at present, are 

 not at all promising. 



Orange Oil, bitter, has moved between 17o#and 19 o4i throughout 

 the summer, with only slight fluctuations, but recently with an upward 

 tendency. 



The present quotation of this oil, of which also the available supplies 

 are but small, is 19 oM per kilo cif. Trieste. 



Orange Oil, sweet. In the month of April this oil changed hands 

 at 17.50 o#. During May this value was maintained, but the excellent 

 development of the flowers, particularly in Calabria, caused the price of 

 orange oil on the spot to fall to 16.50 &M % while simultaneously speculative 

 sales were made here of new oil for delivery at 15.50 c4i to 16 c4i. But 

 the subsequent period of development of the young fruit soon destroyed 

 the high hopes which had been entertained of the new crop. The small 

 fruit dropped in enormous quantities, and in Sicily in particular the fruit 

 on the trees was seriously damaged. Under these influences, and also 

 because spot oil was getting scarcer and scarcer, the prices of old oil 

 again rose in the second half of June to 17.50 cM and in the first days 

 of July they even surpassed this figure; then they stood still for a time 

 at 18.50 o4i y and finally, quite recently, they advanced to 19 c4i. 



The available supplies have gradually been cleared; at the present 

 moment only a few very small remnants are left over and these are 

 growing less every day. The damage suffered by the young fruit in the 

 commencement of the summer has naturally had its effect upon the 

 quotation of the new oil for November/December delivery. 



In view of the fact that the coming orange crop will not be large, it 

 is scarcely likely that the prices of the new oil will be lower in the course 

 of next season, even if the climatic conditions and the oil-content of the 

 new fruit should be favourable for the manufacture of orange oil. 



Bergamot Oil. In the course of the past six months a further series 

 of adulterated bergamot oils has been submitted to investigation in our 

 laboratory; the principal form of sophistication being found to consist in 

 the addition of artificial esters. In the table below we present a synopsis 

 of several samples of this description, in which the deviations, compared 

 with normal bergamot oils, are printed in heavy type in order to render 

 them more distinct. 



So far as specific gravity was concerned, only the first two samples, 

 and in respect of optical rotation only samples 1, 3, 5 and 9 satisfied the
