THE FARMER S VETERINARIAN 



the pastern joint between the small cannon or large 

 pastern bones, and the coffin joint between the 

 coronary and coffin bones. The horse walks upon 

 what corresponds to the nail of the middle finger 

 and middle toe of man. 



In pigs four digits touch the ground, the first 

 being absent and the third and fourth larger and in 

 front of the second and fifth. In ruminants the 

 third and fourth digits reach the ground, while the 

 second and fifth do not. In dogs the first digit 

 appears on the side of the leg, not in contact with 

 the ground. 



ONE OF THE PARASITES OF THE HOG 



The thorn-headed worm attached to the anterior part 

 of the small intestine often causes death. Not more than 

 five or six are usually found in a single animal. 



In fowls the wing, which corresponds to the fore 

 leg of mammals, shows a well-developed humerus, 

 radius and ulna, while only one carpal and one 

 metacarpal bone remain, along which the wing 

 feathers are attached. In the leg the femur and 

 tibia are strong bones, but the fibula is a mere 

 splint. The tarsal bones are absent, while the 

 shank consists of a metatarsal bone (really three 

 bones fused together), to which the four toes are 

 articulated.
