His struggles to subdue the passions that the dreadful recollections of a whole family's butchery awoke in his bosom, only served to add double distortion to his changes of countenance, which, a better index of the convulsion within than were his broken, incoherent, half-inarticulate words, assumed at last an appearance so wild, so hideous, so truly terrific, that Roland was seized with horror, deeming himself confronted with a raging maniac.

He raised his hand to remove that of Nathan, which still clutched his arm, and clutched it with painful force; but while in the act, the fingers relaxed of themselves, and Nathan dropped suddenly to the earth, as if struck down by a thunderbolt, his mouth foaming, his eyes distorted, his hands clenched, his body convulsed,--in short, exhibiting every proof of an epileptic fit, brought on by overpowering agitation of mind.
