J.B., a retired draper, born in 1828, while a youth of seventeen, sustained a fracture of the leg, rupture of the urethra, and laceration of the perineum, by a fall down a well, landing astride an iron bar.

A permanent perineal fistula was established, but the patient was averse to any operative remedial measure.

In the year 1852 he became aware of the presence of a calculus, but not until 1872 did he ask for medical assistance.

He explained that he had introduced a chisel through his perineal fistula to the stone, and attempted to comminute it himself and thus remove it, and by so doing had removed about an ounce of the calculus.

The physician started home for his forceps, but during the interval, while walking about in great pain, the man was relieved by the stone bursting through the perineum, falling to the floor, and breaking in two.
