I have heard that some _English_ chemists have endeavoured to procure
it from _English_ roses.) merely begging to observe that it exactly
corresponds with that given to me by a gentleman who had witnessed the
process in Egypt.
"_Otto of Roses_.--The usual method of making it is, to gather the roses
with their calyces, and put them into a still with nearly double their
weight of pure spring water; which, when sufficiently distilled, will be
highly scented with roses; this is then poured into shallow vessels and
exposed to the nocturnal air. Next morning, the _Atar, or essential oil_
of the flowers is found swimming in small congealed particles on the
surface of the water; it is carefully collected and preserved in small
glass bottles."[1] A hundred pounds of the flowers scarcely afford in
India two drachms of essential oil. "Cent livres de petales de Roses,"
says a French chemist, "N'en fournissent par la distillation que
_quatre_ drachmes." Tachenius from the same quantity obtained half
an ounce, and Hoffman a much larger proportion. The trials of other
chemists have been attended with various results. It is most difficult
to procure the _genuine_ Otto of Roses, since even in the countries
where it is made, the distillers are tempted to put sandal wood, scented
grasses, and other oily plants into the still with the roses, which
alter their perfume, and debase the value of the Atar; colour is no test
of genuineness; green, amber, and light red or pink. The hues of the
_real_ otto, are also those of the adulterated; the presence of the
sandal wood may be detected by the simple sense of smelling; but in
order to discover the union of a grosser oil with the _essential_, drop
a very little otto on a piece of clean writing paper, and hold it to the
fire; if the article is _genuine_, it will evaporate without leaving
a mark on the paper, so ethereal is the _essential oil of roses!_ if
otherwise, a grease-spot will declare the imposition. I need scarcely
expatiate upon the delicate and long-continuing fragrance which this
luxuriant perfume imparts to all things with which it comes in contact;
it is peculiarly calculated for the drawer, writing-desk, &c. since its
aroma is totally unmingled with that most disagreeable effluvium, which
is ever proceeding from alcohol. Lavender-water, _esprit_ de rose &c.
&c. are quite disgusting shut up in box or drawer, but the Atar Gul, is
as delightful there as in th
