Read it through once

While thus perplexed,—and cogitating, among other hypotheses, whether the letter might not have been one of those decorations which the white men used to contrive, in order to take the eyes of Indians,—I happened to place it on my breast. It seemed to me,—the reader may smile, but must not doubt my word,—it seemed to me, then, that I experienced a sensation not altogether physical, yet almost so, of burning heat; and as if the letter were not of red cloth, but red-hot iron. I shuddered, and involuntarily let it fall upon the floor.
