10 General Pathology. 



There is considerable hollowing out on the front of the 

 vertebrae, and, as is usual in such cases, the bones have suffered 

 more than the intervertebral discs, which stand out still com- 

 paratively unchanged. The substance of the bones seems quite 

 normal beyond the absorbed portion. G. C. 3103. 



1. 30. Absorption of Vertebrae from Pressure in Lateral 



Curvature. — Lower four cervical and upper nine dorsal 



vertebree, from a case of lateral curvature — macerated. 



In the concavity of the arch formed by the seventh, eighth, 



and ninth vertebrae on the left side, the bodies have been 



compressed, and are in consequence much less in depth there 



than on the other side, where there is a convexity. This is 



due to the greater compression which always exists upon the 



concavity of an arch, as when a piece of wood is bent upon 



itself. G. C. 1637.

1. 31. From Invasion by Malignant Growth.— Part of the 



left half of the lower jaw of an old person, in which epithelioma 

 of the lip had invaded the bone. 



Just behind the mental foramen the alveolar border of the 

 bone has been invaded and its substance opened out and 

 absorbed. G. C. 2888. 



Presented by Professor Annandale, 1889. 



INFLAMMATION. 



1. 32. Increased Vascularity of an Inflamed Part.— Cast 



in gelatine and glycerine of a left hand, showing a condition 

 of onychia — probably septic and tubercular — in a child aged 

 9 or 10 years. 



Several months before the cast was taken the nail had been bruised . 

 in a gate, and the finger had remained inflamed.
