The author further states that the oil is rarely found in the pure 
state; the bergamot leaves are frequently distilled after turpentine oil 
has been added, and even more often leaves and young saplings of 
bitter orange are added into the still. It is also said that adulterations 
are extensively practised with the addition of peel essences. 
The oil is, however, not only subjected to adulteration, but, according 
to GuUi, it is also itself used as an adulterant, chiefly for mixing with 
oils of petitgrain and of bitter and sweet orange flowers. 
Citron Oil. The statements concerning the properties of citron 
oil published in our April Report, have led to a reply from the London 
Essence Company i), in which that firm endeavours to prove the un- 
reliability of the figures of citron oil given by Gulli and ourselves. 
They also communicate the results of the examination of a citron oil 
obtained from us, which has given figures very different from those 
mentioned by us. 
This we readily admit, but we would at the same time point out, 
that this oil obtained from us cannot possibly have been citron oil; 
it is clear that a mistake has been made in this case in our forwarding 
department, and that, led astray by the name "citron oil", lemon oil 
("Citronen-Oel") has been sent off instead of citron oil (^'Cedro-Oel"). 
But even when this possibility is admitted, the figures given for the 
supposed citron oil are somewhat remarkable. 
S. Gulli refers to the same subject 2) and holds out the prospect 
of a confirmation of his previous statements. 
Oil of lemon has fallen in the course of April to such a low 
level as has not hitherto been known. If it is considered what a colossal 
quantity of lemon oil has been shipped abroad in the first few months 
of the new season, it may be imagined how large the daily deliveries 
must have been in Messina, in order to bring the price of the oil, in 
spite of the enormous export, down to the level of 1,20 lire per 
Sicilian pound, a level which has never been reached before. 
In May and June the lemon trees were still laden with fruit, 
whereas usually at that time of the year the manufacturing season has 
long come to an end. It was an unusual sight, to see over- ripe winter 
lemons adorning the trees side by side with ripe spring fruit 
Unfortunately it is not possible to obtain exact figures of the 
quantities of lemon oil produced during this season, but it may not 
be far off the mark to estimate the quantity produced on the island 
and in Southern Calabria at about 500 tons, a production which has 
never been known before.
