PLATE XXIII. 



Venous Yessels. 

 This figure shows the superficial disposition of the venous ves- 

 sels at the posterior face of the two first phalanges and the venous 

 solar plexus at the inferior face of the third. 



A A' Central discharge of the veins of the sohir plexus. 



B B Venous peripheric canal or circumflex vein. 



C C Veins of discharge of the venous solar plexus in the superficial coronary- 

 plexus. 

 D Posterior face of the superficial coronary venous plexus. On the in- 

 ternal limit of this plexus we see at D the large posterior communi- 

 ca)2t vein which serves as a confluent to the canals emerging from 

 the cartilaginous bulbs and to the posterior part of the solar plexus 

 which discharges itself in it by several different veins. 

 J Continuation of the posterior communicant vein in which the veins of 

 the superficial coronary plexus discharge themselves. It goes and 

 unites at X to the anterior communicant vein to form the dio-ital 

 vein Q Q'. 



N. B. The marks of the lines J, Q Q, and X are prolonged by error in 

 the figure beyond the parts they should indicate. 



R Sheath of the flexor tendons in which transverse divisions ramify them- 

 selves. 

 T T Perforans tendon. 



V Strengthening sheath of the perforans tendon.
