Part 32

The sleep of animals is usually light, especially that of birds, and they are easily startled when at roost. The cackling of the geese on their awaking, you know, saved the Roman capitol. Yet sleep is altogether very nearly balanced with waking. Some animals sleep often, like the cats, but they are long awake, and prowling in the night. The python and the boa are also long awake, and then sleep for many days during the process of digestion. Indeed, all the feræ fall into sound sleep after feeding; while the ruminants scarcely sleep at all; nor do they crouch like the feræ, with the head between the legs: but then their whole life is one scene of quiet; rumination is a mindless reverie. The West Indian slaves and the Hottentots, or woolly bipeds, resemble the brute animal in this, that they fall asleep as soon as their labour is concluded.

That activity of mind in excess may induce even mania, I may offer two impressive, although negative, proofs, from the records of Dr. Rush.—“In despotic countries, and where the public passions are torpid, and where life and property are secured only by the extinction of domestic affections, madness is a rare disease. Dr. Scott informed me that he heard of but one single instance of madness in China.”

“After much inquiry, I have not been able to find a single instance of fatuity among the Indians, and but few instances of melancholy and madness.”

I may add, that Baron Humboldt assures us of this immunity among the wild Indians of South America.

IDA. And may not this melancholy effect be averted by caution and rule? We have a saying in Herefordshire, that “Six hours are enough for a man, seven for a woman, and eight for a fool.”

EV. There cannot be a fixed rule on that point, except the prevailing law of nature,—the feeling of necessity; but this may often lead astray.

It is calculated that one half of a child’s life is passed in sleep, and one quarter to one sixth of the adult existence; but for old age there is no essential period or limit. Old Parr slept almost constantly about the close of his life; while Dr. Gooch records the case of one whose period of sleep was only one quarter of an hour in the twenty-four. It is well to inure an infant to a gradual diminution of its time of sleep, so that at ten years old its period should be about eight hours.

The strength or energy of brain will, when aided by custom, modify the faculty of controlling the disposition to slumber. Frederick the Great, and our own Hunter, slept only five hours in the twenty-four; while Napoleon seemed to exert a despotic power over sleep and waking, even amid the roaring of artillery. Sir J. Sinclair slept eight hours, and Jeremy Taylor three. As a general precept, however, for the regulation of sleep in energetic constitutions, I might propose the wise distribution which Alfred made of his own time into three equal periods,—one being passed in sleep, diet, and exercise, one in despatch of business, and one in study and devotion. Careful habit will often produce sleep at regular and stated periods, as it will render the sleeper insensible or undisturbed by loud noises; the gunner will fall asleep on the carriage amid the incessant discharge of the cannon; and, if I remember right, the slumbers of the bell-ringer of Notre Dame were not broken by the striking of the quarters and the hour close to his ear.

IDA. And at what seasons should we wake and sleep? It seems to me, that the Creator himself has written his precepts in the diurnal changes of this world, that are still so healthfully observed by the peasant, but so strangely perverted by the capricious laws of fashion, and even by the romantic

“sons of night, And maids that love the moon;”

always excepting Astrophel and Castaly. It moves my wonder that they who have looked upon the beauty of a sunrise from the mountain, or the main, can be caught sleeping, when such a flood of glory, beyond all the glare of peace-rejoicings and birth-lights, bursts upon the world.

EV. The wisest have thought with you, Ida, although there was one idle poet, even Thomson, who confessed he had “noe motive for rising early.” It was the custom of Jewel and Burnet to rise at four; and Buffon, we are told, rewarded his valet with a crown, if he succeeded in getting him up before six.

It is to slight the creation, not to enjoy the beauties of daylight; and it is the natural time for sleep, when the dews of night are on the earth. The proof of this:—There were two French colonels who were marching their troops, one by day, the other by night; and the loss in men and horses was very far greater among the night marchers.

CAST. I believe it was Panza, who “never desired a second sleep, because the first lasted from night till morning,”—that immortal Sancho Panza, whose quaint rhapsody we must all echo so gratefully,—“Blessed is he that first invented sleep.” The eulogies of this blissful state, and the wailings of a sleepless spirit, have ever been a favourite theme of the poet, and our own ancient dramatists,—as Beaumont and Fletcher, in the play of “Valentinian,” and Shakspere, from the lips of Henry IV. in his beautiful invocation, and Young, and many others.

EV. Sleeplessness is one of the severest penalties of our nature. In the darkness and silence of night the wakeful mind preys on itself; the pulse is rapid, it is a throb of anguish,—to the wearied thought there is no conclusion, and the parched tongue prays in vain for the morning light. In the curse of Kehama, I think the sleepless lid is one of the most cruel inflictions; and in the severe disorder which we term hemicrania, this curse is to a degree realized.

The sleeplessness of Caligula is related by Suetonius. In Bartholinus, we read of one who slept not for three months, and he became a melancholy hypochondriac. And Boërhave, from intense study, was constantly awake during six weeks.

IDA. We are happy in our quiet minds, are we not, dear Castaly? Yet, if we are ever summoned to the couch of one wearied by night watching, Evelyn will tell us how we may soothe the pillow of a sleepless mind, to which the secret of inducing slumber would be a priceless treasure.

EV. Study the causes of insomnia, or sleeplessness, Ida; as those which excite nervous irritability,—coffee, green tea, small doses of opium, the protracted use of antimony, &c.; and believe not in the virtues of vulgar remedies, often as dangerous as they are ridiculous. There is a batch of these which Burton has gleaned from various authors; as a sample,—nutmegs, mandrakes, wormwood; and from Cardan and Miraldus,—the anointing the soles of the feet with the fat of a dormouse, and the teeth with the ear-wax of a dog, swine’s galls, hares’ ears, &c.

I might offer to you many plain precepts for the alleviation of the light causes of sleeplessness; and while I dole them out to you in very dullness, you will fancy my gold-headed cane to my chin, and other essential symbols of an Esculapius of the olden time. Adopt, then, a free ventilation in summer, and airing in winter, of the chamber. This should never be a mere closet, always above the ground floor, neither very light nor dark, the window not being close to the bed, and, above all, not in the vicinity of stoves, ovens, and large kitchen fires. Do not allow the windows to be open throughout the night, to admit the cold dew or air; and, in winter, the basket-fire should be placed there for an hour before you enter your chamber. A slight acceleration of the circulation may be produced by gentle exercise before rest; and two or three wafer biscuits or spring water, to prevent the wakeful effects of both chilliness and hunger. A light woollen sock may be worn, which is unconsciously displaced when sleep comes on, and the night-cap should be little more than a net, except during the very cold months. The position of the body should be that which is the easiest, except the supine, which induces congestion and often “night mare;” and if there be much sensitiveness of the surface, the hydrostatic bed should be employed, but that not too long, as it will become heated by protracted pressure. Children should not be enveloped in clothes, nor crowded in bed; nor should infants be shaken, or tossed, or patted, as foolish nurses too often do.

There are many simple modes of inducing slumber: I allude not to poppy and henbane, nor to the pillow of hops, which, in the case of the third George, was the charm that sealed up the lids of the king; but to other modes, such as a tedious recital, (something like my own dull prosing,) the gentle motion of a swing, a cot or cradle, the ripple of a stream, and the dashing of a waterfall, the waving of a fan, the caw of rooks, the hum of bees, the murmur of an Æolian harp—

CAST. So gracefully wound up in that quaint morceau, the “Fairy Queen,” when Archimago sends the spirit to fetch a dream from Morpheus—

“Cynthia still doth steepe In silver dew his ever-drooping head, Whiles sad night over him her mantle black doth spred.

And more to lull him in his slumber soft, A trickling stream, from high rocke tumbling downe, And ever dringling rain upon the loft, Mix’d with a murmuring winde, much like the soune Of swarming bees, did cast him in a swoune.”

SUBLIMITY AND IMPERFECTION OF DREAMING.

“We are such stuff As dreams are made of, and our little life Is rounded by a sleep.” TEMPEST.

EV. In the transition to and from the repose of sleep, the mind is sinking into oblivion, and thought is fading, and the senses and sensation are overshadowed in their regress to insensibility: even instinct is well nigh a blank. This is the state of slumber. Then, I believe, and only then, are we ever wandering in the ideal labyrinth of DREAMS.

There is a curious calculation of Cabanis, that certain organs or senses of the body fall asleep at regular progressive periods; some, therefore, may be active while others are passive, and in this interesting state, I may hint to you, consists the essence of a dream. It seems that in dreamless sleep, the senses fall asleep altogether, as in the case of Plutarch’s friends, Thrasymenes and Cleon, and others who never dreamed.

ASTR. So there is some truth in the fanciful conceit of Cardanus, that “Sleep is the rest of the spirits,—waking their vehement motion, and dreaming their tremulous motion.”
