I was struck dumb with these Reflections, as one astonish'd, and had not a Word to say, no not to answer to my self, but rise up pensive and sad, walk'd back to my Retreat, and went up over my Wall, as if I had been going to Bed, but my Thoughts were sadly disturb'd, and I had no Inclination to Sleep; so I sat down in my Chair, and lighted my Lamp, for it began to be dark: Now as the Apprehension of the Return of my Distemper terrify'd me very much, it occurr'd to my Thought, that the Brasilians take no Physick but their Tobacco, for almost all Distempers; and I had a Piece of a Roll of Tobacco in one of the Chests, which was quite cur'd, and some also that was green and not quite cur'd.
我的反省,在我生病的第二天和第三天,把我压得透不过气来。由于发热,也由于良心的谴责,从嘴里逼出了几句类似祈祷的话。然而,这种祈祷,有口无心,既无良好的愿望,也不抱任何希望,只是恐惧和痛苦的呼喊而已。这时,我思想极度混乱,深感自己罪孽深重,而一想到自己将在如此悲惨的境况下死去,更是恐怖万分。我心灵惶恐不安,不知道自己嘴里说了些什么话,只是不断地呼喊着这样的话:&上帝啊,我多可怜啊!我生病了,没有人照顾我,我是必死无疑了!我该怎么办啊?&于是,我眼泪夺眶而出,半天说不出话来。
