adhering to it; and the third side adheres to the bone. Where 

 it subtends the notch of the acetabulum, the cotyloid ligament 

 is re-enforced by additional ligamentous fibres, placed beneath 

 it, and going from the upper to the lower end of the notch. 

 These fibres consist of two planes, one internal and the other 

 external, partly crossing each other, and adhering closely to 

 the cotyloid ligament. 



The Inter-Articular, or Round Ligament, (Lig. Teres,) is a 

 true ligamentous band, which is attached at the one end to the 

 pit on the head of the os femoris, and aftevwards by a slight 

 dissection, is easily separated into two fasciculi. Of these, the 

 lower one may be traced to the inferior end of the cotyloid 

 notch, where, winding around the prominence of bone, it begins 

 to adhere to the ischium, and continues to do so from that 

 point along the anterior face of the ischium, just below the 

 acetabulum, to a point between the latter and the upper ante- 

 rior part of the tuber. The other portion is directed towards 

 the superior end of the notch, and is attached there by two ex- 

 tremities, one near the margin of the acetabulum, and the other 

 three or four lines from it within.* The fibres of the round 

 ligament are somewhat intermixed also with those of the coty- 

 loid ligament subtending the notch. 



The Capsular Ligament (Capsula Fibrosa) is the strongest in 

 the body, and represents a conoidal sac, open at both extremi- 

 ties, by which it adheres to the bones. It is fixed by its base 

 to the circumference of the acetabulum, beyond the cotyloid 

 ligament, and to this ligament itself, where the latter subtends 

 the notch. It embraces that part of the head of the os femoris 

 which projects above the margin of the acelabulum, and de- 

 scends along the neck to its root. It is longer in front; is fixed 

 there to the oblique line which runs between the two trochan- 

 ters, and, behind, into the root of the neck, a little in advance 

 of the posterior oblique ridge, and in such a manner as to leave 

 a small part of the neck of the os femoris bare below it. Above, 

 it is fixed to the neck, just below the rough fossa in the tro- 

 chanter major; and on the under surface of the neck it adheres,
