High division of brachial artery (right). 



In this subject the radial artery comes off from the brachial 

 opposite the lower border of the subscapularis muscle. It runs 

 parallel to and in close contact with the brachial artery under the 

 deep fascia. It gives off no recurrent branch at the elbow, but a 

 recurrent artery arises from the brachial just above the insertion of 

 the biceps muscle. This high radial was not found in the left arm of 

 the subject.

Occurrence of a duodenal fossa. 



At the duodeno-jejunal junction or the fourth part of the 

 duodenum, a diverticulum of the intestine occurred. It protruded 

 backwards, upwards and outwards from the back of the intestine, 

 lying in a small fossa. When not distended, its size was that of a 

 small walnut. The diverticulum lay in a fossa, which had definite 

 boundaries on all sides. Above it was the middle colic artery ; on 

 the left, a branch from the middle colic artery passed down to 

 anastomose with the colica sinistra ; on the right side lay the superior 

 mesenteric artery and vein. The left renal vein was in relation with 

 the diverticulum behind, lying between it and the vertebral column. 

 In front it had a covering of peritoneum. The diverticulum lay 

 entirely behind the intestine, which, in the natural position, concealed 

 it from view. 



On distension, the characters of the diverticulum were more evi- 

 dent. In shape it appeared globular, and measured about two inches 

 in its long diameter and one inch in its transverse diameter.
