6, 305. Syphilitic Enlargfement of the Femur.— Section of 



a femur — macerated, illustrating the above. 



The surface is irregular and the interior greatly condensed 

 or sclerosed. F. P. C. 408.

6. 306. Syphilitic Enlargrement of the Femur.— Right femur, 



lower end in section — macerated, illustrating the above. 



There are two enlargements of the bone, one on the upper 

 half, the other on the lower half of the shaft, but they are dis- 

 connected at the middle. The lower is the larger. Although 

 its surface is rough, the bone forming it is much condensed.

6. .307. Syphilitic Enlarg-ement of the Femur.— Left femur, 



from the same subject as the last — macerated, illustrating the 

 above. 



The bone is increased in weight and is thickened, espe- 

 cially towards its lower end. The thickening extends all round 

 the bone at the junction of the lower and middle thirds. 

 Above the first thickening, and separated from it by a small 

 area of almost unchanged bony surface, there is another, a little 

 below the small trochanter. The surface of the upper thick- 

 ening is porous, but that of the lower one is smooth. The 

 apertures for blood-vessels are greatly enlarged above the lower 

 articular surface. B. C. i. 5. M. 54. 



6. 308. Syphilitic Enlargement of the Femur.— Right femur 



— macerated, illustrating the above. 



The bone is condensed and heavy, and the surface irregu- 

 larly thickened. A small bony spicule projects upwards from 

 the linea aspera, where it branches to pass to the inner condyle.
