Congenital Malformations. 577 



The specimen shows the relation of parts in a case where 

 the tibia was congenitally absent. The lower end of the femur 

 is rounded, and had no articulation except with the patella. 

 The fibula is well formed and straight. The astragalus is 

 altered in shape, and articulates with the lower end of the 

 fibula. The foot is twisted inwards, and the heel is drawn up 

 as in talipes equino-varus. The muscles and tendons are fairly- 

 well developed. G. C. 3369.
