cyst, a considerable quantity of which is still seen adhering to the bound- 

 aries of the cavity, particularly to the outside of the dura matral covering 

 of the spinal marrow. This matter had pressed on the spinal marrow 

 so as to produce paralysis of the lower extremities. A very excellent pre- 

 paration, as illustrative of the effects of this disease (1804)."

— Parapleg"ia. — Right half of the lower dorsal and upper 

 lumbar portions of the spine — in spirit, illustrating the above. 



The patient had suffered from spinal disease, with paraplegia, for 

 some years, and died of phthisis in the Hospital for Incurables. At 

 the posi - mortem examination a large abscess was found surrounding 

 the bodies of the affected vertebrae. This abscess contained, besides 

 curdy pus, several loose fragments of hard necrosed bone, which had been 

 driven back, by the pressure of the adjacent vertebrte, upon the spinal 

 canal. 



These fragments, found at the post-mortem examination, 

 are shown in situ, having been embedded in dark paraffin 

 before the section was made, in order that their relative 

 position might be maintained. 



It may be noted that the curvature, which corresponds to 

 what existed at the time of death, is comparatively^ slight. 

 This is important as showing that a minor degree of curvature 

 may co-exist with involvement of the spinal cord.

7. 239. Tuberculosis, with Destruction of Bodies — Atrophy 

 of Ribs and Spines, and Paraplegria.— Eight half of a 



spine representing the lower seven dorsal vertebrae (sixth to 

 twelfth inclusive), with portions of the lower seven ribs attached. 

 Soft parts partially dissected — in spirit, illustrating the above. 



The patient, a young man aged 20, about two years before ad- 

 mission to the Royal Infirmary, Edinburgh, first noticed a pain in the 

 lower dorsal region of his spine, when he stooped or straightened his 

 back. The pain was dull and aching, and extended along the ribs on 

 the left side, which corresponded to the painful part of the spine. It 

 gradually increased, and in about six months had become constant,
