When large doses are taken, all the above effects are hastened and heightened in proportion. The period of depression comes on sooner; the prostration of energy increases to actual stupor, with or without dreams; the pulse becomes feeble, the muscles exceedingly relaxed; and, if enough has been taken, death ensues.
Of course, all these effects are modified by the constitution of the individual, by the length of time he has accustomed himself to take it, and by the circumstances in which he is placed. But upon all persons, and in all circumstances, its final effects, like those of ardent spirits taken in large and repeated doses, are equally melancholy and degrading. “A total attenuation of body,” says Dr. Oppenheim, “a withered, yellow countenance, a lame gait, a bending of the spine, frequently to such a degree as to assume a circular form, and glassy, deep-sunken eyes, betray the opium-eater at the first glance. The digestive organs are in the highest degree disturbed: the sufferer eats scarcely any thing, and has hardly one evacuation in a week. His mental and bodily powers are destroyed: he is impotent.”
The influence upon the mental faculties of Haschisch, or East Indian hemp, when taken in large doses, is no less extraordinary than that of opium.
That accomplished traveller, Bayard Taylor, when in Damascus, “prompted,” as he says, “by that insatiable curiosity which led him to prefer the acquisition of all lawful knowledge through the channel of his own experience,” was induced to make a trial of this drug. Not knowing the strength of the preparation he employed, he found himself, shortly after taking the second dose, more thoroughly and completely under the influence of the drug than was either pleasant or safe.
Speaking of the effects of the stronger dose, he says, “The same fine nervous thrill of which I have spoken suddenly shot through me. But this time it was accompanied with a burning sensation at the pit of the stomach; and, instead of growing upon me with the gradual pace of healthy slumber, and resolving me, as before, into air, it came with the intensity of a pang, and shot throbbing along the nerves to the extremities of my body. The sense of limitation—the confinement of our senses within the bounds of our own flesh and blood—instantly fell away. The walls of my frame were burst outward, and tumbled into ruin; and, without thinking what form I wore,—losing sight even of all idea of form,—I felt that I existed throughout a vast extent of space. The blood pulsed from my heart, sped through uncounted leagues before it reached my extremities; the air drawn into my lungs expanded into seas of limpid ether; and the arch of my skull was broader than the vault of heaven. Within the concave that held my brain were the fathomless deeps of blue; clouds floated there, and the winds of heaven rolled them together; and there shone the orb of the sun. It was—though I thought not of that at the time—like a revelation of the mystery of Omnipresence.”
EFFECTS OF FEAR.
It is a common practice, in many parts of India, to oblige persons suspected of crimes to chew dry rice in presence of the officers of the law. Curious as it may appear, such is the intense influence of fear on the salivary glands, that, if they are actually guilty, there is no secretion of saliva in the mouth, and chewing is impossible. Such culprits generally confess without any further efforts. On the contrary, a consciousness of innocence allows of a proper flow of fluid for softening the rice.
Many of our readers are familiar with the case of the thief to whom, in common with other suspected persons, a stick of a certain length was given, with the assurance that the stick of the thief would grow by supernatural power. The culprit, imagining that his stick had actually increased in length, broke a piece off, and was thus detected. A similar anecdote is told of a farmer who detected depredations on his corn-bin by calling his men together and making them mix up a quantity of feathers in a sieve, assuring them, at the same time, that the feathers would infallibly stick to the hair of the thief. After a short time, one of the men raised his hand repeatedly to his head, and thus betrayed himself.
A Parisian physician, during his visits made in a hired fly, had received a bottle of real Jamaica rum as a sample, but found, after returning home, that he had left it in the carriage. He went to the office, and informed the manager that he had left a virulent poison in one of the carriages, and desired him to prevent any of the coachmen from drinking it. Hardly had he got back when he was summoned in great haste to three of these worthies, who were suffering from the most horrible colic; and great was his difficulty in persuading them that they had only stolen some most excellent rum.
One of the most singular examples on record of the effect of fear acting through the imagination is given by Breschet, a French author of the sixteenth century, who informs us that the physicians at Montpellier, which was then a great school of medicine, had every year two criminals, the one living, the other dead, delivered to them for dissection. On one occasion they determined to try what effect the mere expectation of death would produce upon a subject in perfect health; and in order to carry out the experiment they told the gentleman (for such was his rank) who was placed at their discretion, that, as the easiest mode of taking away his life, they would employ the means which Seneca had chosen for himself, and would therefore open his veins in warm water. Accordingly they covered his face, pinched his feet, without lancing them, and set them in a footbath, and then spoke to each other as if they saw that the blood was flowing freely, and life departing with it. The man remained motionless; and when, after a while, they uncovered his face, they found him dead.
