walker; and know how the thing is. In this sort of disturbed, unsound sleep, the eyes are not closed, and are attracted by the light. I used to get up and go towards the window, and make violent efforts to throw it open. The air in some measure revived me, or I might have tried to fling myself out. I saw objects indistinctly, the houses, for instance, facing me on the opposite side of the street; but still it was some time before I could recognise them or recollect where I was: that is, I was still asleep, and the dimness of my senses (as far as it prevailed) was occasioned by the greater numbness of my memory. This phenomenon is not astonishing, unless we chuse in all such cases to put the cart before the horse. For in fact, it is the mind that sleeps, and the senses (so to speak) only follow the example. The mind dozes, and the eye-lids close in consequence: we do not go to sleep, because we shut our eyes. I can, however, speak to the fact of the eyes being open, when their sense is shut; or rather, when we are unable to draw just inferences from it. It is generally in the night-time indeed, or in a strange place, that the circumstance happens; but as soon as the light dawns on the recollection, the obscurity and perplexity of the senses clear up. The external impression is made before, much

in the same manner as it is after we are awake; but it does not lead to the usual train of associations connected with that impression; e. g. the name of the street or town where we are, who lives at the opposite house, how we came to sleep in the room where we are, &c.; all which are ideas belonging to our waking experience, and are at this time cut off or greatly disturbed by sleep. It is just the same as when persons recover from a swoon, and fix their eyes unconsciously on those about them, for a considerable time before they recollect where they are. Would any one but a German physiologist think it necessary to assure us that at this time they see, but with their eyes open, or pretend that though they have lost all memory or understanding during their fainting fit, their minds act then more vigorously and freely than ever, because they are not distracted by outward impressions? The appeal is made to the outward sense, in the instances we have seen; but the mind is deaf to it, because its functions are for the time gone. It is ridiculous to pretend with this author, that in sleep some of the organs of the mind rest, while others are active: it might as well be pretended that in sleep one eye watches while the other is shut. The stupor is general: the faculty of thought

itself is impaired; and whatever ideas we have, instead of being confined to any particular faculty or the impressions of any one sense, and invigorated thereby, float at random from object to object, from one class of impressions to another, without coherence or control. The conscious or connecting link between our ideas, which forms them into separate groups or compares different parts and views of a subject together, seems to be that which is principally wanting in sleep; so that any idea that presents itself in this anarchy of the mind is lord of the ascendant for the moment, and is driven out by the next straggling notion that comes across it. The bundles of thought are, as it were, untied, loosened from a common centre, and drift along the stream of fancy as it happens. Hence the confusion (not the concentration of the faculties) that continually takes place in this state of half-perception. The mind takes in but one thing at a time, but one part of a subject, and therefore cannot correct its sudden and heterogeneous transitions from one momentary impression to another by a larger grasp of understanding. Thus we confound one person with another, merely from some accidental coincidence, the name or the place where we have seen them, or their having been concerned with

us in some particular transaction the evening before. They lose and regain their proper identity perhaps half a dozen times in this rambling way; nor are we able (though we are somewhat incredulous and surprised at these compound creations) to detect the error, from not being prepared to trace the same connected subject of thought to a number of varying and successive ramifications, or to form the idea of a whole. We think that Mr. Such-a-one did so and so: then, from a second face coming across us, like the sliders of a magic lantern, it was not he, but another; then some one calls him by his right name, and he is himself again. We are little shocked at these gross contradictions; for if the mind was capable of perceiving them in all their absurdity, it would not be liable to fall into them. It runs into them for the same reason that it is hardly conscious of them when made.

"That which was now a horse, a bear, a cloud, Even with a thought the rack dislimns,

And makes it indistinct as water is in water."

The difference, so far then, between sleeping and waking seems to be, that in the latter we have a greater range of conscious recollections, a larger discourse of reason, and associate ideas

wave.

in longer trains and more as they are connected one with another in the order of nature; whereas in the former, any two impressions, that meet or are alike, join company, and then are parted again, without notice, like the froth from the So in madness, there is, I should apprehend, the same tyranny of the imagination over the judgment; that is, the mind has slipped its cable, and single images meet, and jostle, and unite suddenly together, without any power to arrange or compare them with others, with which they are connected in the world of reality. There is a continual phantasmagoria: whatever shapes and colours come together are by the heat and violence of the brain referred to external nature, without regard to the order of time, place, or circumstance. From the same want of continuity, we often forget our dreams so speedily: if we cannot catch them as they are passing out at the door, we never set eyes on them again. There is no clue or thread of imagination to trace them by. In a morning sometimes we have had a dream that we try in vain to recollect; it is gone, like the rainbow from the cloud. At other times (so evanescent is their texture) we forget that we have dreamt at all; and at these times the mind seems to have been a mere blank, and sleep presents only
