PATHOLOGICAL ANATOMY. 



Post mortem examination reveals a contracted uterus and 

 the symptoms of a normal process of involution. The large 

 intestines are usually filled with dry faeces; no inflammation 

 is present. Those cases in which imfl unmation of the small 

 intestines is observed in all probability depend on puerperal 

 infection (see further clown). 



The omasum contains a great deal of dry food. The liver 

 is always of a lighter color, but this is also met with in cows 

 slaughtered for other reasons — for instance, in cases of fatal 

 hemorrhage due to rupture of the uterus. The kidneys are 

 mostly normal ; occasionally parenchymatous inflammation is 

 noticed. The large bronchi sometimes contain some feed ; 

 some animals show a foreign body pneumonia. The deep 

 muscles of the thigh are occasionally necrotic (Guillebeau and 

 Hess). 



The changes in the brain are variable. Harms (also 

 Borinann) found small round air bubbles in the veins of the 

 pia mater. 



In some' autopsies large quantities of transparent serum 

 were found under the dura mater and in the ventricles. 

 (Harms, van Dulm). 



Van Dulm and Hannel observed decided injection of the 

 cerebral vessel, with extravasation, in consequence of which 

 the cerebral substance exhibited a hemorrhagic infiltration. 



Most autopsies are conducted on slaughtered cows. Thus 

 the bleeding gives a more favorable anatomo-pathological 

 picture, than if the animal had died. This must be given 

 due consideration when the meat is to be consumed. There 

 are also cases of acute puerperal septicaemia in which the 

 uterus shows but few microscopic changes. The latter are 



often very dangerous, as (lie following case shows:
