third and fourth metatarsal bones, after covering the tendon of the 

 peroneus longus muscle. The short or deep-seated plantar liga 

 ment lies close to the bones, being separated from the superficial part 

 by some cellular tissue. Its breadth is considerable, its length scarcely 

 an inch. One extremity is attached to the calcaneum in front of the 

 long ligament, the other, somewhat expanded, to the under surface of 

 the cuboid bone, internal to the tuberosity. 



The dorsal or superior ligament is a flat band of fibres which 

 connects the anterior and upper surface of the calcaneum with the 

 adjacent part of the cuboid bone. 



The internal or interosseous ligament is placed deeply in the 

 hollow between the astragalus and os calcis, and is closely connected 

 with the external calcaneo-scaphoid ligament. 



A separate synovial membrane lines this joint.

 and culoid lones are connected by a dorsal liijameni, composed of short

 3, lower posterior tibio-jjcroneal ligament ; 4, middle part of the external lateral ligament 

 of the ankle-joint, passing to the calcaneum ; 5, anterior part of the external lateral 

 ligament of the ankle-joint, passing to the astragalus ; below the last ligament the 

 external calcaneo-talar ligament has not been represented in this figure ; 6, posterior part 

 of the external lateral ligament of the ankle-joint, passing to the astragalus ; 7, is placed 

 above the interosseous calcaneo-talar ligament ; 8, dorsal calcaneo-scaphoid ; 9, dorsal 

 calcaneo-cuboid ; 10, part of the long plantar or calcaneo-cuboid ; 11, superior talo-sca- 

 phoid ; 12 and 13, second and third scapho-cuneiform, and between them one of the 

 intercuneiform ligaments ; 14, superior scapho-cuboid ; 15, placed on the external 

 cuneiform bone, points to the cuneo-metatarsal ligaments from that bone to the second, 

 third, and fourth metatarsal bones ; 16, cuneo-metatai-sal ligament, from the first cunei- 

 form to the second metatarsal bone ; between 12 and 16, are seen the cuneo-metatarsal 

 ligaments which converge from the three cuneiform bones on the second metatarsal ; 17, 

 cubo-metatarsal ligament passing to the fourth metatarsal bone ; 18, that to the fifth,
