PLATE X. 



This figure represents the posterior face of the digital region, 

 flexed backward in a manner to show in its full extent the inferior 

 or plantar face of the foot. 



The skin has been lifted from aoove the third phalanx, and the 

 enveloping sheaths of the tendons are dissected. The velvety tis- 

 sue is preserved. 



A Median part of the pyramidal body (fleshy frog) of plantar cusliion, or 



sensitive tissue of the sole. 

 B Branches of the pyramidal body. 

 C Cartilaginous bulb. 



E Angle of inflection of the branches of the pyramidal body. 

 F Point or apex of the fleshy frog. 



J Interval of separation of the two branches of the perforatus. 

 L Lateral lacunsB of the pyramidal body. 

 M Median lacunae of the pyramidal body. 

 Q Q Fibrous sheath of union of the two branches of the perforatus. 



R Branches of the perforatus directing themselves towards their point of 



insertion at the second phalanx. 

 T Tendon of the perforatus. 

 T' Tendon of the perforans at its passage between the branches of the 



perforatus. 

 V Strengthening sheath of the plantar aponeurosis. 

 X Lateral bands of the strengthening sheath of the plantar aponeurosis, 



which cross the direction of the branches of the perforatus to go and 



attach themselves on the lateral parts of the first phalanx.
