metatarsal bone, which is deeply lodged between the 

 tarsal segments. The chief bond of union between 

 this bone and the tarsus is effected by a strong 

 inter osseous ligament 

 that passes between 

 it and the internal 

 cuneiform. In Fig. 59 

 the knife is placed in 

 the position required 

 to divide that liga- 

 ment. 



Fig. 60 shows the 

 position of the more 

 important structures 

 that are divided in 

 amputation of the 

 great toe together with 

 its metatarsal bone. 



The nerve sup- 

 ply of the lower 

 limb. In Fig. 61 is 

 shown the cutaneous 

 nerve - supply of the 

 inferior extremities on 

 both the anterior and 

 the posterior aspect. 



limbs are common, but 

 are more often due to 

 some lesion in the 

 inferior segment of the cord than to damage received 

 by any one individual nerve. Cases, however, are 

 recorded where a single trunk has been injured and a 

 limited form of paralysis has followed in consequence. 

 Paralysis of the anterior crural nerve 

 has been caused by injuries to the lower part of the 

 vertebral column implicating the cauda equina, by
