I have, in one instance, seen the cord almostcompletely separated at the point of fracture, although the displace-ment of the fragments was inconsiderable. Accompanying the paralysis of the bladder, there has been generallyobserved an alkaline state of the urine, and subacute inflammation ofthe coats of the bladder. Priapism is present in a certain proportionof cases. Those who die immediately seem to be asphyxiated; while thosewho die later seem to wear out from general irritation, this conditionbeing frequently accompanied with an obstinate diarrhoea and vomit-ing. A few become comatose before death. It will be seen, moreover, that a certain proportion finally recover;but scarcely ever are all the functions of the limbs and of the bodycompletely restored. We shall render this part of our description of these accidents moreintelligible if we regard them as they occur in the various portions of. OMique fracture of the bodyof a vertebra.

Fracture of the Bodies of the Lumbar Vertebrae. The spinal cord terminates, in the adult, at the lower border of thefirst lumbar vertebra, but in the child at birth it extends as low asthe third lumbar vertebra. The remainder of the vertebral canal isoccupied by the leash of terminal nerves, called collectively the caudaequina. The nerves which emerge from the intervertebral foramina belowthe fourth and fifth lumbar vertebra?, unite with the sacral nerves toform a plexus which supplies the sphincter and levator ani, the peri-neal muscles, the detrusor and accelerator uringe, the urethra, theglans penis, and a great proportion of the lower extremities. It willbe apparent, therefore, that a fracture, with displace
