The character and extent of the lesions, with the repara- 

 tive efforts in a surviving case, are well shown in Figs. 83 and 

 84, in which it is seen that the peritoneum, prepubian tendon 

 and abdominal tunic have all parted just anterior to the pubis 

 and passed forward about half way to the sternum, dragging 

 with them, for a part of the way, the teats. Posterior to these 

 and occupying the area previously filled by them, is an extensive 

 expansion of dense connective tissues, C, which has assumed the 

 functions of the ruptured parts. 



In Fig. 84 it is shown that the subperitoneal fat, A, does not 

 invade the ruptured area, E, but seems to depend for its forma- 

 tion upon the presence of the peritoneum. 



The prognosis of complete rupture of the prepubian tendon 

 is very grave, since most mares, along with their foals, perish 

 before the conclusion of the pregnancy during which the rupture 

 occurs.

 accident occurred, is safely passed, the animal may thereafter
