528 Diseases of Joints. 



The cause of the absorption of the lamince is still obscure, 

 A possible clue may be found in the pressure which must have 

 been present at one time upon the intervertebral nerves. The 

 portion examined by Dr. "Woodhead was found to show no sign 

 of tubercular disease. G. C. 3105. 



Presented btj A. G. Millek, F.R.C.S.E., 1889. 



7. 240. Tuberculosis, with Atrophy of Ribs and Spines, 

 and Paraplegfia. — Left half of the previous specimen — in 

 spirit, illustrating the above. 



Atrophy of the vertebral ends of the ninth, tenth, and 

 eleventh ribs is well shown. The pleura is greatly thickened and 

 adherent, and the remains of the cavity similar to that on the 

 other side is seen. G. C. 3106. 



Presented by A. G. Miller, F.R.C.S.E., 1889. 



7. 241. Tubercular Disease, with Destruction of Bodies.— 



Lower cervical, dorsal, and lumbar portion of the spine of a 

 child, with ribs attached — partly macerated, illustrating the 

 above. 



There has been extensive destruction of the bodies of the 

 last two dorsal and first lumbar vertebrae. The front of the 

 vertebrae that remain from the fourth dorsal to the second 

 lumbar inclusive have evidently been bared of periosteum and 

 ligament, and their surfaces are rarefied and eroded. The spine 

 is acutely bent where the vertebrae have been destroyed, so that 

 the body of the eleventh dorsal touches that of the first lumbar.

7. 242. Tubercular Disease, with Destruction of the 

 Bodies. — Lumbar vertebrae of a child — in spirit, illustrating 

 the above. 



"From a child affected with lumbar abscess, which projected, and 

 was evacuated at the groin."
