might have remained to the present time, even if I had never made use
of opium, I think that the experience of all who have undergone the
trial shows that similar pains are invariably attendant upon the
disuse of opium. How long their presence might be protracted with
persons not antecedently troubled in this way, is a question I can not
answer. I infer from what little has been recorded, and from what I
have learned in other ways, that the reforming opium-eater must make
up his mind to a protracted encounter with this great enemy to his
peace. That the struggle of others with this difficulty will be
prolonged as mine has been I do not believe, unless they have been
subjected for a lifetime to pains connected with disorder in the
nervous system.

The unnatural sensitiveness to cold to which I have alluded is rather
a discomfort than any thing else. It merely makes a higher temperature
necessary for enjoyment, but in no other respect can it be regarded as
deserving special mention. With the thermometer standing at 80 to
85 the sensation of agreeable warmth is perfect; with the mercury at
70 or even higher, there is a good deal of the feeling that the bones
are inadequately protected by the flesh, that the clothing is too
limited in quantity, and in winter that the coal-dealer is hardly
doing you justice.

The cold perspiration down the spine, which was so marked a sensation
during the worst of the trial, has not yet wholly left the system, but
is greatly limited in the extent of surface it affects and in the
frequency of its return.

The tendency to impatience and irritability of temper to which I have
adverted is by far the most humiliating of the effects resulting from
