Pelvis. 



ANATOMY.— The pelvis (Figs. 115, 118, and 119), in the hind 

 quarters, corresponds to the two shoulder blades of the forehand. 

 The two halves (one on each side) of the pelvis are united together 

 at their lower- and posterior ends. Their upper ends (posterior

iliac spines) rest on the sides of the backbone, to which they are 

 strongly attached by ligaments, and form the highest point of 

 the croup. The most forward portion of the pelvis at each side, 

 is the " point of the hip " (anterior iliac spine) ; and the rearmost 

 portion "the point of the buttock" (tuberosity of the ischium). 

 The hip joint, on each side, is formed by the head of the thigh 

 bone (Figs. 115 and U6) and a cavity in the pelvis (" Hip ioint," 

 Fig. 118).
