the right and the latter to the left lung. Each branch penetrates 

 the lung near the bronchus. These arteries divide, or branch, 

 similarly to the bronchi. Following the branchings of the bronchi, 

 they finally terminate into the lung capillaries, forming networks 

 on the bronchi and the air-tube terminals. 



The cord-like remnant of the ductus botalli, or embryonal connec- 

 tion between the lung arterial trunk and the anterior aorta, has 

 been observed but is rare in grown birds. 



The arteries, the veins, and the lymphatic vessels of birds anas- 

 tomose far more frequently than those of mammals.
