PLATE XI. 



Arterial Vessels. 



The figure shows the deep disposition of the digital ar- 

 tery at the posterior face of the first two phalanges, and in the 

 interior of the third seen from its inferior face. 



A, A'. Digital artery. 



C. Perpendicular artery at its point of origin. 



H. One of the branches running posteriorly, destined to the per- 

 forkns tendon, in which it ramifies itself. 



J. Deep-seated branch. 



K. Point of origin of the artery of the plantar pad. 



M. Deep transverse branch, completing behind the front superficial 

 coronary circle. 



S. Plantar artery or posterior terminal branch, in the plantar fissure, 

 and in the semi-lunar sinus, where it forms with its analogue the 

 semi-lunar anastomosis. 



V, V. Radiated divisions of the digital artery emanating from the con- 

 vexity of the semi-lunar anastomosis, and following the direction 

 of the descending canals of the third phalanx to go and con- 

 tribute to the formation of the circumflex artery at the exterior 

 circumference of the notched border of the bone.
