the head and neck ; while the subclavian 

 divides into a brachial artery for the wing and 



a large pectoral artery 

 chiefly concerned in 

 carrying blood to the 

 large pectoral muscular 

 mass. 



From the neighbour- 

 hood of the right bron- 

 chus, the aorta passes 

 backwards ventral to 

 the vertebral column, 

 supplying paired inter- 

 costal and lumbar 

 arteries corresponding 

 to the intervals be- 

 tween the vertebrae. 

 The following arteries 

 are also furnished to 

 the organs within the 

 abdomen and pelvis and 

 to the legs. The single 

 coeliac artery supplies 

 the liver, spleen, glandular stomach, gizzard, 

 and a part of the intestine. The cranial 

 mesenteric artery, also single, furnishes blood 

 to most of the intestine. The paired renal
