secondly to the greater facility with which the damaged fruit, by means 
of the reduced railway rates, could be placed on the Upper -Italian 
and even on the Swiss and German markets. 
At the same time, the high prices have brought about a certain 
increase in the production and a reactionary movement downwards, 
which, however, has come to an end at the present quotation, and 
which in all probability will soon again make place for higher prices. 
The stocks of this oil at disposal amount at most to 7000 kilos, 
and the Sicilian market must be considered as practically exhausted. 
Orange Oil, bitter. This oil has only been produced in very 
small quantities, as the fruit gave an exceptionally low yield. For this 
reason the prices have advanced right from the commencement to the 
unusual level of 15 marks. In the course of the summer the quotations 
of this article will probably advance still further. 
Eucalyptus Oil. There has lately been on the market an excellent 
selection of oils rich in eucalyptol, among which the Australian product 
ranked first. The production in Portugal has also increased con- 
siderably, but Algeria is no longer able to compete. For example, of 
a contract for 10000 kilos which we had made with a French distiller, 
only a small part could be executed. 
In commerce, eucalyptol has gained the upper hand, and its cheap 
price may possibly lead to a gradual displacement of the ordinary oil. 
The fact that it has been possible to create with little expenditure 
such a perfect product, may truly be called a triumph of technical 
science. When comparing the quotations, the constants of the pure 
body should be taken into consideration. Our eucalyptol has a melting 
point of — 1°, and is optically inactive. 
In the last runnings of a distillation of the oil of Eucalyptus globulus, 
we observed crystals which were freed from the adhering oil by pressing 
them on a tile, and by recrystallisation from 70 per cent, alcohol were 
obtained in the form of brilliant, almost odourless needles of the 
melting point 88,5°. The boiling point was determined at 283° (755 mm),
