In calves ■which are very large and dead, and where we

 especially in a juvenile pelvis, it is better to remove one or both 

 fore legs subcutaneously than to draw the head forcibly into 

 the pelvic canal. 



The head descended between the fore legs. 



The depression may be limited, so that the ears lie op- 

 posite the anterior border of the pubis, but the upper border

 tion. In such a case it is advisable to repel the calf and ex-

 can be readily reached. 



The prognosis is favorable when the calf is alive and the
