_Different Senses fall Asleep successively._--The different senses become inactive and fall asleep, not all at once, but successively. First, sight goes. The eye-lids droop, and close. Taste and smell probably next. Touch, and hearing, are among the last to give way. Hence, noises so easily disturb us, when falling asleep. Hence, too, we are most easily awaked by some one repeating our name, or by some one touching us. These senses are also the first to waken. One sense may be asleep and another awake. You may still hear what one is saying that sits near you, when already the eye is asleep. So in death, one _hears_ when no longer able to see or to speak. 2. _Loss of personal Control._--Accompanying this loss of self-consciousness is the loss of _personal control_, _i. e._, the control of the will over the bodily organization. This follows from the inactivity of the senses and of the nervous system, for it is only through that, and not by direct agency of the will, that we, at any time, exert voluntary power over the body. When that system becomes exhausted, and its force is spent, so that it can no longer furnish the motive power, nor execute the commands of the higher intelligence the will no longer maintains its empire over the physical organization, its little realm of matter, its control is suspended, its sceptre falls, and it realizes for the time the story of the enchanted palace on which a magic spell had fallen, suddenly arresting the busy tide of life, and sealing up, on the instant, the senses of king, courtiers, and attendants, in the unbroken sleep of ages. _Indications of approaching Sleep._--One of the first indications, accordingly, of the approach of sleep, is the relaxing of the muscles, the drooping of the eye-lid, the dropping of the head and of the arm, the sinking down of the body from an erect to a supine position. If in church, the head seeks the friendly support of the pew in front, fortunate if it can secure itself there from the still further demands of gravitation. _Analogous Cases._--In respect to the point now under consideration, the loss of control over the physical frame, the phenomena of sleep closely resemble those of intoxication, and of fainting; and for the same reason, in either case, _i. e._, the inactivity of the nervous system, which is the medium of voluntary power over the body. That inactivity of the nervous system is produced in the one case by natural, in the other by unnatural causes, but the direct effect is the same as regards the loss of voluntary power. The same effects are also produced in certain diseases, and eventually by death.
