vessels. It may be noted that the position of the tendinous 

 attachments about the great trochanter shows little or no 

 tendency to ossification, and, while the new masses of bone 

 seem to have run into the substance of some of the muscles, 

 other muscles in the neighbourhood — for instance, the iliacus — 

 seem to have escaped entirely. The whole bone is very heavy.

6. 374. Ossification in Adductor Magnus Muscle ("Myositis 



Ossificans"). — Plaster cast of a left femur in the Barclay 

 Collection, illustrating the above. 



Attached to the femur there is a large mass, corresponding 

 to the position of the adductor magnus muscle. The new bone 

 Avas cancellous in texture. G. C. 3292. 



6. 375. Ossification in Vastus Internus Muscle ("Myositis 



Ossificans"). — Right femur, lower end injured — macerated, 

 illustrating the above. 



About the middle of the inner and anterior surface of the 

 shaft there is a projecting piece of bone, which has apparently 

 been an ossification in the vastus internus muscle.

6.376. Ossification in Crureus Muscle ("Myositis 



Ossificans "). — Left femur, lower end missing — macerated, 

 illustrating the above. 



A piece of bone projects from the anterior and outer 

 surface of the bone, about the middle, and has apparently been 

 an ossification in the crureus muscle. G. C. 1869.
