The cystitis had entirely disappeared, and he was able, with some effort, to pass his urine without the aid of a catheter.

Sensation in both extremities had slightly improved, and he was able to slightly move the toes of the right foot.

This being his condition, an operation was proposed as the only means of further and permanent improvement, and to this he eagerly consented, and, accordingly, on the 25th of August, the 9th dorsal vertebra was trephined.
"The cord was found to be compressed and greatly congested, but there was no evidence of laceration.

The laminae and spinous processes of the 8th and 9th dorsal vertebrae were cut away, thus relieving all pressure on the cord; the wound was drained and sutured, and a plaster-of-Paris jacket applied, a hole being cut out over the wound for the purpose of changing the dressing when necessary.

By September 1st union was perfect, and for the next month the patient remained in excellent condition, but without any sign of improvement as to sensation and motion.
