 (3) between the calcaneus and the cuboid; (4) between the cuboid and the lateral 

 two metatarsals; (5) between the first cuneiform and the first metatarsal; (6) a 

 complicated and extensive one, which branches out between the navicular and 

 cuneiform bones; between the cuneiforms; between the third cuneiform and the 

 cuboid; between the second and third cuneiform and the second and third meta-

Dorsal artery. — The line of this is from the centre of the ankle-joint to the 

 upper part of the first interosseous space. 



On its mfMlial .side i.s the tenrlon of the extensor hallucis lonsus; on its lateral, the most medial 

 tendon of the e.xtensor digitorum lonfi;iis. It is crossed by the most medial tendon of tlie extensor 

 brevis. The origin of this muscle should be noted on the lateral and fore part of the calcaneus. 



Cutaneous nerves (fig. 1182). — Tlu; sites of these, numerous on the dorsum 

 of the foot, arc; as follows: — The superficial peroneal (musculo-cutaneous) nerve, 

 liaving perforated tlu; fascia in t\\c lower third of tiie leg, divides into two chief 

 branches, medial and lateral, which suj)ply all the toes save the lateral part of the 

 littl(!, and the adjacent sides of the first and second. The deep peroneal becomes 

 cutaneous in the first space, and is distributed to the contiguous sides of the above-
