Remembering that Chinaman's face, I can not wonder at the popular notion regarding the abandonment of opium. Men say it is a mental pain; because spiritual woe is the expression of the sufferer's countenance. And so it is, but this woe is underlain by the keenest brute suffering. Let me sketch the opium-eater's experience on the rugged road upward. Let us suppose him a resolute man, who means to be free, and with that intent has reduced to a hundred drops the daily dose which for several years had amounted to an ounce of laudanum. I am not supposing an extreme case. An ounce of laudanum is a small _per diem_ for any man who has taken his regular rations of the drug for a twelvemonth. In the majority of cases I have found an old _habitué's_ daily portion to exceed three, or the equivalent of that dose in crude opium or morphia; making seventy-two grains of the gum or twelve of its most essential alkaloid. In one most interesting case I found a man who having begun on the first of January with one half a grain of sulphate of morphia for disease, at the end of March was, to all appearance, as hopeless an opium-eater as ever lived, taking thirty-two grains of the salt per day in the form of _Magendie's Solution_. This, however, was an unusual case. According to my experience the average opium-eater reaches twelve grains of morphia in ten years, and may live after that to treble the amount: the worst case I ever knew attaining a dose of ninety grains, or one and a half of the drachm vials ordinarily sold. I am happy, in passing, to add that for more than two years both the extreme cases just mentioned have been entirely cured. If the opium-eater has been in the habit of dividing his daily dose he begins to feel some uneasiness within an hour after his first deprivation, but it amounts to nothing more than an indefinite restlessness. In any case his first well-marked opium torments occur early after he has been without the drug for twenty-four hours. At the expiration of that time he begins to feel a peculiar _corded_ and _tympanic_ tightness about the epigastrium. A feverish condition of the brain, which sometimes amounts to absolute _phantasia_, now ensues, marked off into periods of increasing excitement by a heavy sleep, which, after each interval, grows fuller of tremendous dreams, and breaks up with a more intensely irritable waking. I have held a man's hand while he lay dreaming about the thirty-sixth hour of his struggle. His eyes were closed for less than a minute by the watch, but he awoke in a horrible agony of fear from what seemed to have been a year-long siege of some colossal and demoniac Vicksburg.
