Ungueal preplaktar. — Passes through the notch of 

 the lateral extremity of the os pedis, goes to the 

 preplantar fissure, runs forwards, and ends by divisions 

 dipping into the os pedis. / ^ ^<n4^v.vw^ u^ U""^ 



Ungueal plantar. — Lodged in the plantar fissure, 

 then in the plantar canal, and into the semi-lunar 

 sinus of the os pedis, it anastomoses wtt^h that of the 

 opposite side, forming tlie semi-lunar arch. Collateral 

 branches ascend to form the anterior laminal of 

 Spooner, and descend to form the inferior commu- 

 nicating arteries. 



Veins. — Digital veins, wliicli form in tb.e foot a rich
