Cryptogram from Frankenstein; or, the modern prometheus, chapter 10

We rest; a dream has power to poison sleep. We rise; one wand'ring thought pollutes the day. We feel, conceive, or reason; laugh or weep, Embrace fond woe, or cast our cares away; It is the same: for, be it joy or sorrow, The path of its departure still is free. Man's yesterday may ne'er be like his morrow; Nought may endure but mutability!

The sentence you are solving goes here.

As I said this I suddenly beheld the figure of a man, at some distance, advancing towards me with superhuman speed. He bounded over the crevices in the ice, among which I had walked with caution; his stature, also, as he approached, seemed to exceed that of man. I was troubled; a mist came over my eyes, and I felt a faintness seize me, but I was quickly restored by the cold gale of the mountains. I perceived, as the shape came nearer (sight tremendous and abhorred!) that it was the wretch whom I had created. I trembled with rage and horror, resolving to wait his approach and then close with him in mortal combat. He approached; his countenance bespoke bitter anguish, combined with disdain and malignity, while its unearthly ugliness rendered it almost too horrible for human eyes. But I scarcely observed this; rage and hatred had at first deprived me of utterance, and I recovered only to overwhelm him with words expressive of furious detestation and contempt.
