drags his toe on the ground in attempting to walk. 

 The horse also goes down-hill with great difficulty. 

 In some cases, there is considerable heat and swell- 

 ing, and great pain when the shoulder is pinched. 

 If the leg is lifted high up and drawn out forcibly 

 forward, it causes great pain. This mark distin. 

 guishes the strain of the shoulder from any disease 

 or lameness of the foot, that it causes great pain to 

 extend the limb forward, and y in standing, the horse 

 places the leg before him not stretched out straight, but 

 bent and resting on the toe. After this condition of 

 things has continued some time, a sinking in or de- 

 pression is shown at the crest or top of the shoulder- 

 blade, from inflammatory action and wasting of sub- 

 stance, to which the term SWENEY has been given. 



Strain of the haunch, in which the animal halts a 

 little, spares the affected limb as much as possible, 

 and can neither trot or gallop When the strain is 

 but slight, the animal scarcely limps in walking, and 

 seems only pained when urged at a faster gait ; when 

 it is severe, even standing is painful, the animal 

 limps in walking, and drags his leg ; and in trotting, 

 his buttocks describe a sort of swinging movement. 

 It is often very difficult to detect it, but its presence 

 may be inferred when a careful examination can dis- 

 cover no injury or lesion in any other part of the 

 limb, and especially if the horse will not permit his 

 haunch to be examined. It differs from spavin in 

 that the lameness increases rather than diminishes 

 by walking.
