THE CITRINE ODOURS. 85 
name of “Curacao des Les” and “Curacao de Hollande.” The 
first, which is derived from unripe fruits, appears in the form of 
thick, hard solid sections, of a strong, persistent pleasant odour 
and bitter taste. The second description is derived from ripe 
fruits from which the white pith has been removed in Holland, 
and is in the form of extremely thin yellowish-red rinds, externally 
wrinkled and very aromatic. The dried rind is also exported 
from Italy and Provence, made either from the small young green 
fruit or from the more mature yellow fruit, but from both of 
which the inner white pith has not been removed. All of these 
descriptions of rinds are used for the manufacture of Curacao 
liqueur, alcoholic tinctures, and for flavouring syrups. 
The “Curacao” liqueur is made in Holland, mainly from the 
orange-peel imported from the island of Curacao, and it is named 
after the island as a sort of guarantee of its quality, for un- 
deniably the finest orange-peel in the world comes from there. It 
is said that this island produces the bitterest of bitter oranges 
with the oiliest of rinds, also the sweetest of sweet oranges with 
the finest flavoured fruit, but the soil cannot be persuaded or 
forced into growing sour fruit. Lemons and limes planted there 
turn sweet and die. Immense quantities of bitter orange-peel are 
shipped from there every year, nearly all to Holland. In Amster- 
dam there is a regular orange-peel market, where saucers full of 
peels are set out as samples on long tables, and testers go among 
them selectmg for purchase. Such experience have these men 
that they can tell by simply breaking and smelling a bit of peel 
what part of the tropical world it comes from, and that from 
Curacao always commands a higher price than any other. 
The bark and all the tender parts of the Amyris acuminata, on 
being bruised or wounded, discharge a pale whey-coloured fluid, 
which possesses a fragrance something like that of the orange- 
leaf*. 
Flowers of somewhat similar odour to orange-blossom are pro- 
duced by the Philadelphus coronarius, known as the Syringa or 
Mock orange, a shrub which is somewhat common in England, 
and quite distinct from the genus Citrus. The perfume of the 
Gardenia citriodora and of the Cytisus laburnum is also considered 
of this type.
