REMARKS
ON
ETHERS.
61
The
operator should
avoid,
as far
as
is
practicable,
the
excessive
use,
either
singly
or
combined,
of
any
aroma,
or
perfume,
that
would
indicate
its
own
pre-
sence
;
that
this
would
be
an
injurious
result,
must
be
obvious.
In
imitating
the
aroma
of
brandy,
the
ethers
will
be
found
to
be
the
most
valuable.
The
aro-
ma
of
cordials
have
been
greatly
neglected
by
manu-
facturers.
Why
this
should
be
the
case
is
certainly
astonishing,
since
this
addition
could
be
made
at
an
insignificant
cost.
The
consumer
of
these
articles
will
find
it
more
economical
to
manufacture
them,
as
the
same
articles,
when
found
in-
commerce,
contain
adulterations
to
a
greater
or
less
extent,
and
the
chemical
preparations
particularly,
which
are
made
by
the
manufacturing
chemists
to
suit
the
low
price
paid
for
them,
are
largely
adulterated.
The
articles
in
question
will
be
arranged
rather
with
a
view
to
their
importance
and
availability,
than
to
an
alphabetical
arrange-
ment.
GENERAL
REMARKS
ON
ETHERS.
They
consist
of
acetic
ether,
butyric
ether,
nitric
ether,
chloric
ether,
and
sulphuric
ether.
Owing
to
their
extreme
volatility,
they
should
be
excluded
from
the
air.

good,
