 to his kennel, and the limbs should not be strained by 

 allowing him to jump up and down on a bench, a low bed 

 being provided. In five or six weeks the thigh or hind leg 

 is united, and the fore leg in three weeks or a month.

 the knee and toes commonly, in the hip very often, in the stifle 

 occasionall}^, and in the hock very seldom, excejjt in connexion 

 with fracture. In all cases, they are detected by the deformity

 restoration by gentle handling, and is not accompanied by the 

 crepitus which marks the fracture. To reduce a dislocation, 

 two persons must lay firm hold of the two parts of the limb 

 on each side of the injured joint, and then extending them

 be felt to slip into the socket. It is only, however, in the knee, 

 that any inexperienced operator is likely to succeed, for in the 

 hip, which is the most common seat of dislocation, great tact 

 and knowledge of the anatomy of the part are required to 

 efiect a cure. Plere the head of the bone may be removed 

 from the socket in three different directions, namely, either 

 forwards, upwards, or backwards, and the pull must be in the 

 direction of the socket, or it will do harm rather than good.
