6. 93. Thickening- of the Surface of the Tibia with 

 Absorption of the Interior, probably from Chronic 



Suppurative OsteO-myelitiS. — Lower end of a right tibia 

 — macerated, shoAving the above. 



There has been a considerable crust of new periosteal bone 

 on the surface, which has been, however, partly broken oflf. 

 The original surface of the bone is porous, and at places has 

 been opened into small holes. G. C. 1 1 47.

d. Where the changes in the bone tissue have resulted in an abscess. 



6. 94. Abscess in the Lower End of the Radius. — Lower end 

 of a left radius — macerated, showing the above. 



Above the articular surface there is considerable enlarge- 

 ment and hollowing out of the interior, probably due to 

 chronic suppuration. Three cloacal apertures communicate 

 with the inside, and through them pieces of rarefied and 

 apparently necrotic bone can be seen. The surface has the 

 irregular character of newly-formed bone wdien due to the 

 irritation of suppurative organisms, B. C. i. 5. M. 14. 



6. 95. Abscess in the Lower End of the Femur.— Left femur 



— macerated, to show the above. 



The lower half of the bone is greatly enlarged by new and 

 irregular formation on the surface.. The interior is hollowed 

 out, and formerly contained fragments of necrosed bone. This 

 has evidently been a case of suppuration within the lower end 

 of the bone, causing osseous development on the outside.

6. 96. Abcess in the Lower End of the Tibia.— Section of 



a left tibia with fibula, showing the above.
