At this stage the plants are best suited to the process of trans- 
ferring to the plantations. During the next two years the latter must 
be tended with care, and yield yet nothing. 
From the third year onw^ards the trees begin to flower, and the crop 
can already be estimated at 150 to 200 francs per hectare (2 Y2 acres). 
It is, however, necessary to see that the trees do not grow to a greater 
height than 2,5 to 3 m. This is done by cutting off the tops, which 
at the same time causes a powerful development of the lateral branches 
and an abundant formation of blossoms, so that the yield becomes 
very remunerative. 
The flowering period of the ylang ylang trees commences in Reunion 
from January to February, but a regular formation of blossoms giving 
the best yield can only be reckoned upon from May to August. Those 
blossoms which are freshest when submitted to distillation yield oils of 
better quality. 50 to 64 kilos of freshly gathered blossoms produce 
I kilo oil, i. e. 1,56 to 2 ^/q. The yield from one hectare of plantation 
laid out according to Flacourt is annually from 3 to 4 kilos oil, giving 
a net profit from 1116 to 1616 francs. 
Ylang Ylang **Schimmel & Co." (German pat. No. 142 858). 
The demand for this excellent product was extremely brisk. This proves 
that the quality of our product meets with unanimous approval, and 
equals that of the best commercial brands. It is only intended to 
compete with the latter; where the requirements are not so high, a 
good rectified cananga oil will generally suffice. 
We once more beg to call attention to our product, being convinced 
that trials made with it will give complete satisfaction. 
Italian Pharmacopoeia. 
To the new Editions of the Pharmacopoeias which we have hitherto 
discussed in these pages, in so far as regards essential oils or their 
constituents, we now add the new (second) edition of the Italian 
Pharmacopoeia, published last year. Here also we find the tests pres- 
cribed, etc., remodelled to a considerable extent, so that the advance, 
as compared with the previous edition, is unmistakable. Among the 
substances newly added is eucalyptol, whilst oil of bitter oranges and 
rose oil have been struck off the list of official oils. 
Although the information given in the new Italian Pharmacopoeia 
is, on the whole, correct, it requires in some places correction or 
amplification; for this reason we reproduce in the following pages the 
requirements given for the individual oils and preparations, in order 
to be able to discuss any details in as clear a manner as possible.
