monly the case, the upper part of the spinal column is displaced 

 in front of the lower. G. C. 1473.

 Thomson of St Andrews, 1833. 



3. 80. Fracture of the Spine in the Mid-Dorsal Region.— 



Fifth to ninth dorsal vertebrae — macerated and dried — showing 

 the above injury. 



The seventh vertebra has suffered most of all. Its body is 

 comminuted, its transverse processes broken off, and its laminae 

 fractured near the pedicles. The front of the eighth body 

 has been broken off; also the following transverse processes, 

 the right of the fifth vertebra, both of the sixth, and the left of 

 the eighth and ninth. The fracture has evidently been pro- 

 duced by bending forward the spine, with the usual tendency 

 to forward displacement of the upper fractured portion of the 

 column. G. C. 3309. 



3. 8 1 . Displacement forward of the ninth Dorsal Vertebra 

 and partial Fracture of the tenth, with Crushing- of 

 the Cord. — Section of the lower half of the ninth and of the 

 tenth, eleventh, and twelfth dorsal vertebrae. The muscles are 

 dissected off, and the preparation is mounted in spirit, to show 

 the above injury. 



The patient, a miner, set. 29, was doubled forwards by a mass of 

 earth falling upon his shoulders. He had complete loss of motion and 

 sensation in his lower limbs. He could not make water, but the bladder 

 emptied itself after a catheter had been inserted. A plaster jacket was 

 applied. On the third day he had septic cystitis, very fcetid urine, and 

 considerable pain across the abdomen. 



On the ninth day he died of collapse, with vomiting, belching, and 

 abdominal symptoms. 



At the post-mortem examination the bladder was found to have 

 sloughed into the peritoneum, and his death had been due to septic 

 peritonitis. 



The body of the ninth dorsal vertebra has been crushed
