branches. The median branch (d) is the longest and strongest, 

 and takes its lower attachment in the middle of the fibro-carti- 

 laginous lip found on the upper border of the posterior face of 

 the second phalanx. The two lateral branches (d') approach each 

 other as they descend, and terminate on the sides of the rough- 

 ened triangle on the posterior face of the first phalanx. 



6. The deep inferior sesamoid ligament (Fig. 13, e) is quite short, 

 and consists of a number of distinct, thin fibrous bands lying 

 directly against the bone and entirely covered by the median 

 and lateral inferior sesamoid ligaments. These fibrous bands 

 cross one another in passing from the sesamoids to the first 

 phalanx. 



II. The coronary joint is the simplest of the three articula- 

 tions of the foot. The long pastern furnishes two condyles and 

 the short pastern two glenoid cavities. Besides a capsular liga- 

 ment there are — 



1. Two lateral coronary ligaments {k) and, 



2. 8ix posterior coronary ligaments, — namely, two superior cor- 

 onary ligaments (h), two median coronary ligaments {h'), and two 

 inferior coronary ligaments (g). 



III. The pedal articulation (" coffin" joint) is an imperfect 

 hinge-joint, and is formed by the condyles at the lower end of 

 the short pastern and the two glenoid cavities in the united upper 

 surfaces of the pedal and navicular bones. Besides the capsular 

 ligament (Figs. 12 and 13, 1), which binds all three bones together, 

 there are the following accessory ligaments : 



1. Two strong lateral ligaments, an external and an internal 

 (Fig. 11, i), whose posterior borders are lost in the lateral carti- 

 lages which cover them. 



2. Two lateral suspensory ligaments of the navicular bone {k). 

 They begin on the posterior border and ends of the navicular 

 bone, and terminate on the lower part of the anterior surface of 

 the OS suffraginis, where they are lost in the lateral ligaments of 

 the coronary articulation. 



3. The lateral ligaments of the lateral cartilages, navicular bone,
