At the very instant when he brought the loop over his head previous to slipping it beneath his arm-pits, and when the old gentleman before-mentioned (who had clung so tight to the railing of the bridge as to resist the force of the crowd, and retain his position) earnestly warned those about him that the man was about to lower himself down--at that very instant the murderer, looking behind him on the roof, threw his arms above his head, and uttered a yell of terror.

'The eyes again!' he cried in an unearthly screech.

Staggering as if struck by lightning, he lost his balance and tumbled over the parapet. The noose was on his neck. It ran up with his weight, tight as a bow-string, and swift as the arrow it speeds. He fell for five-and-thirty feet. There was a sudden jerk, a terrific convulsion of the limbs; and there he hung, with the open knife clenched in his stiffening hand.

The old chimney quivered with the shock, but stood it bravely. The murderer swung lifeless against the wall; and the boy, thrusting aside the dangling body which obscured his view, called to the people to come and take him out, for God's sake.

A dog, which had lain concealed till now, ran backwards and forwards on the parapet with a dismal howl, and collecting himself for a spring, jumped for the dead man's shoulders. Missing his aim, he fell into the ditch, turning completely over as he went; and striking his head against a stone, dashed out his brains.
