But I had still other precautions to take in regard to sleepwalking. To me it has always been incomprehensible how so many men can go to bed, and lie down at their ease there, without reflecting that perhaps, in the first sleep, they may get up again as Somnambulists, and crawl over the tops of roofs and the like; awakening in some spot where they may fall in a moment and break their necks. While at home, there is little risk in my sleep: because, my right toe being fastened every night with three ells of tape (I call it in jest our marriage-tie) to my wife's left hand, I feel a certainty that, in case I should start up from this bed-arrest, I must with the tether infallibly awaken her, and so by my Berga, as by my living bridle, be again led back to bed. But here in the Inn, I had nothing for it but to knot myself once or twice to the bed-foot, that I might not wander; though in this way, an irruption of villains would have brought double peril with it.--Alas! so dangerous is sleep at all times, that every man, who is not lying on his back a corpse, must be on his guard lest with the general system some limb or other also fall asleep; in which case the sleeping limb (there are not wanting examples of it in Medical History) may next morning be lying ripe for amputation. For this reason, I have myself frequently awakened, that no part of me fall asleep. [Note 19: It is easier, they say, to climb a hill when you ascend back foremost. This, perhaps, might admit of application to political eminences; if you still turned towards them that part of the body on which you sit, and kept your face directed down to the people; all the while, however, removing and mounting.]
