for the most part covered with lymph. At some places the 

 compact tissue at the seat of fracture is smooth and bare.

3. 268. Uniting" badly-set Fracture of the Tibia and 



Fibula. — Portions of the shafts of the tibia and fibula, with 

 the muscles dissected off — in spirit, showing the above. 



The upper fragment of the tibia is uniting to the lower 

 fragment of the fibula, and the other fragments of each bone 

 are free. The medullary cavities, where exposed, have been 

 covered in, apparently as yet by soft material. The opposed 

 fragments of the tibia and fibula have, however, been united 

 by spongy bone, a slight crust of which is also seen on the 

 adjacent tibia. G. C. 1053.

3. 269. United Fracture of the Tibia and Fibula.— Lower 



half of a right tibia and fibula. The limb was injected, the 

 bone cleaned, and put into weak acid, then dried and placed in 

 turpentine. 



The fibula, near the lower end, has an indistinct fissure, and 

 shows considerable enlargement and bony growth on the surface, 

 as if this part had lain beneath an ulcer. The tibia has been 

 irregularly broken about four inches above the ankle-joint, and 

 the uniting medium is more vascular than the surrounding bone. 

 The internal malleolus appears to have been broken off, and to 

 have re-united. B. C. i. 1 M. 43. 



3. 270. United Oblique Fracture of the Shaft of the 

 Tibia. — Section of the lower half of a right tibia — macerated,, 

 showing the above.
