Arthur Mervyn by Charles Brockden Brown

This scene lasted I know not how long. Insensibly the passions and reasonings of Welbeck assumed a new form. A grief, mingled with perplexity, overspread his countenance. He ceased to contend or to speak. His regards were withdrawn from me, on whom they had hitherto been fixed; and, wandering or vacant, testified a conflict of mind terrible beyond any that my young imagination had ever conceived.

For a time he appeared to be unconscious of my presence. He moved to and fro with unequal steps, and with gesticulations that possessed a horrible but indistinct significance. Occasionally he struggled for breath, and his efforts were directed to remove some choking impediment.
