The real truth is, that _no_ narcotic of any kind whatever is harmless, but on the contrary, invariably pernicious when taken otherwise than by the advice and under the treatment of a medical man. True, sleeplessness is one of the most trying things a person can suffer from; but then there are other means of combating the enemy than by dosing one's self with chloral or any such agent; and thus making an infirmity chronic, which would in all probability have been only a temporary evil. Rely upon opiates for sleep, and sleep will not come without them. Thus a bad habit is formed; the bodily strength is undermined, the digestive powers enfeebled, the mind and intellect weakened and enervated, and the unfortunate sufferer becomes a slave, bound hand and foot to a habit that it is almost impossible to shake off. Sleeplessness often comes from want of sufficient fresh air and exercise, from over-mental work, mental distress, from too great a quantity of stimulants taken during the day, and from various other causes, which a little care as to diet and regimen would quickly overcome. Taking short naps during the day; too much tea and coffee drinking, especially shortly before bedtime--all these are apt to cause sleeplessness. In many cases a light and simple supper taken shortly before retiring to rest, and attention to the feet being thoroughly warm, will insure a good night's sleep when more energetic means have failed. In those terrible abodes of suffering, our cancer hospitals, the method of all others most resorted to, and most efficacious for the alleviation of pain, is the sub-cutaneous (under-the-skin) injection of morphia. In sciatica, neuralgia, and other painful nervous affections, this remedy is often exceedingly beneficial, when used under competent medical advice and supervision; but like every other good thing it is open to great abuse, and often made use of merely as a soothing narcotic by the irritable, excitable, and discontented. A long train of evils follows; but with these we are not called upon to deal here. What we want now to lay before the reader is a plain statement as to the prompt treatment called for in a case of over-narcotism from too strong a dose of injected morphia. Coldness of the extremities, lividity of the countenance, profuse cold sweat, and loss of power over the limbs, insensibility, very deep breathing, and contraction of the pupils of the eyes to such an extent that they resemble a black pin-head, result.
