The hand now glides down along the shin, holding it firmly, flexes the fetlock, and draws ifc into the pelvic canal, holding the fet- lock, coronet and claws in the hand (fig. 42), The greatest difiiculty consists in the fact that the calf's buttocks enter the pelvic inlet with each pain, thus interfering with the retraction of the leg. In order to overcome this and to render reposition possible, the following treatment has been recommended : 1. Keposition should be performed in the standing cow with her hindquarters raised. 2.
