On August 23d I removed the stone without difficulty by the lateral operation through the perineum.

The lobe of the prostate was enlarged, which seemed to favor the extent of the incision beyond what would otherwise have been safe.

The perineum was deep and the tuberosities of the ischii unnaturally approximated.

The calculus of the mixed ammoniaco-magnesian variety was egg-shaped, and weighed 19 drams.

The arrow-point was completely covered and imbedded near the center of the stone.
