Abnormal comes nervi mvdiani artery. 



An artery arises at the separation of the common interosseous 

 from the nlnar and passes down closely adherent to the radial side of 

 the median nerve to the annular ligament, under which it crosses in 

 front of the nerve. This vessel joins the superficial palmar arch at 

 the origin of the digital artery, supplying the opposing sides of the 

 index and middle fingers, and is continued on as the common trunk 

 of the radialis indicis and the princeps pollicis. This was observed 

 on both sides.

Obturator hernia. 



In this case the hernia occurred in an elderly subject, and con- 

 sisted of a cone of peritoneum, much thickened with fat and pelvic 

 fascia, measuring '2 cm. from the apex to the middle of the base 

 the base having a diameter of 1/5 cm. The sac, consisting of ob- 

 turator membrane, projected through an oval opening measuring 

 2*2 cm. in its long diameter and was directed downwards, forwards 

 and outwards along the groove at the upper and outer part of the 

 obturator foramen, being just over the upper border of the obturator 

 externus muscle, with the obturator nerve and artery below and 

 behind it. The base of the hernia was closed in, and the region 

 of it readily explorable through the vagina. 



On the other side there existed a femoral hernia.

 passes in front of the axillary vessels. It then divides, forming a
