Following each attempt he had a violent chill and intense evening fever.

On the thirty-third day Terrilon removed the pencil by operation.

Symptoms of perivesical abscess were present, and seventeen days after the operation, and fifty days after the introduction of the pencil, the patient died.

Caudmont mentions a man of twenty-six who introduced a pencil-case into his urethra, from whence it passed into his bladder.
It rested about four years in this organ before violent symptoms developed.

Perforation of the bladder took place, and the patient died.
Poulet mentions the case of a man of seventy-eight, in whose bladder a metallic sound was broken off.
