the cavity of the knee-joint. (5) The subcutaneous mfra- 

 patellar bursa, placed directly beneath the skin anterior to the 

 proximal part of the ligamentum patella. (6) The deep infra- 

 patellar bursa, which is placed between the ligamentum 

 patellae and the anterior surface of the proximal part of the 

 tibia. The suprapatellar bursa and the deep infrapatellar 

 bursae are practically always present, but one or more of the 

 subcutaneous and subfascial bursae may be absent. Not un- 

 commonly a subfascial and an adjacent subcutaneous bursa 

 may communicate through an aperture in the deep fascia. 

 The subcutaneous bursae are often destroyed during the 

 reflection of the skin, but the deeper bursae can usually be 

 found, if looked for carefully, in the situations mentioned 

 above.

Ligament Inguinale (O.T. Pouparfs Ligament) Liga- 

 mentum Lacunare (O.T. Gimbernat's Ligament). Although, 

 properly speaking, both of these ligaments belong more to 

 the abdominal wall than the thigh, it is essential that the 

 dissector should obtain some knowledge of their connections 

 before he proceeds further with the dissection. The inguinal 

 ligament is merely the thickened lower border of the apo- 

 neurosis of the external oblique muscle of the abdominal wall 

 folded backwards upon itself. It thus presents a rounded 

 surface towards the thigh, and a grooved surface towards the
