 its posterior extremity gives origin to two slips or cords, one superior, tin- 

 other inferior. The first, the strongest and longest, terminates in tho fossa 

 near the posterior extremity of the intercondyloid notch. Tho second, thin 

 and flat, is inserted on the posterior outline of tho external tibial facet.

The external border of this meniscus is separated from the external lateral 

 ligament by the tendon of the popliteus muscle, and acts, with regard to this 

 tendon, as a pulley. 



Node of union. The bands which bind this complicated articulation aro 

 very numerous. They will 1x3 successively described as : 1, Those whicli 

 attach the patella to the tibia ; 2, Those which unite the femur with the tibia. 



A. Ligaments attaching the patella to the tibia. The patella is bound to 

 the tibia by three funicular ligaments, designated by the generic epithet of 

 " patellar." They are situated in front of the articulation, and are charged
