other two at its proximal end, and anterior 

 distally. 



At the distal end of the hone, the three meta- 

 tarsals separate from one another, and each 

 ends in a pulley-like surface for the corresponding 

 digit. 



b. The first metatarsal is incomplete, its distal end 



being alone present. It is a small irregular 

 nodule of bone, attached by ligament to the inner 

 and posterior surface of the tarso-metatarsus, a 

 short distance above its distal end. 



c. The digits. The four preaxial digits are present. 



In many domestic fowls, notably Dorkings, an 

 extra or supernumerary toe is present on the 

 inner side of the foot. The true fifth, or postaxial 

 digit, is always absent. 



i. The hallux, or great toe, is connected with the 

 first Baetatarsal, and directed backwards. It 

 consists of two phalanges, the last one bearing 

 a claw. 



ii. The second toe is directed forwards and slightly 

 inwards. It has three phalanges, the last one 

 clawed. 



iii. The third toe is the largest, and is directed for- 

 wards. It has four phalanges, the terminal 

 one clawed. 



iv. The fourth, ioe is directed forwards and out- 

 wards. It has five phalanges, and the distal 

 one is clawed.
