10. In rabbit 85 beside the thyreoid ima being present, the left sub- 
clavian takes its origin on the arch, and the superficial cervical 
of the right side passes out from the common stalk of the inter- 
costo-mammary artery. The subclavian of the left side forms a 
short corona. 
11. In rabbit 52 the innominate (brachio-cephalic) artery is the only 
vessel originating on the arch of the aorta, and subsequently sub- 
divides as shown giving rise to a long corona typed left subclavian, 
left and right carotid arteries, and right subclavian artery. This 
condition thus typifies that found normally in the horse.
