TYPHOID PNEUMONIA. 235 



^own — if tlie debility disappears — and, finally, if the cougli be- 

 comes more loose, or the animal coughs freely and without 

 dread, we may hope for the best, and prognosticate accordingly ; 

 but if the pulse continue high, the breathing quick, the cough, 

 low and suppressed — if symptoms of abdominal disease are 

 present, and particularly if there should be discharged from the 

 nose sanious yeasty-looking matter of a most offensive nature — 

 if the limbs remain cold in spite of everything done to bring 

 warmth within them, then our prognosis will be unfavourable ; 

 for it is more than probable that death will speedily ensue. 



Appeaeances aeteb Death. — The state of the animal 

 after death will, in a great measure, depend upon the intensity 

 and duration of the disease. In the most severe forms of the 

 malady, nearly the whole of the organism will be found more 

 or less gangrenous. The appearances are, disorganisation of 

 the lungs, with large deposits of lymph upon the pleura cos- 

 talis ; efiusion of water within the chest, in which masses of 

 lymph, and portions of the lungs and of the pleura, will be 

 found floating about. The pleura will also be gangrenous ; it 

 will slough away from the ribs like as much wet paper, leaving 

 exposed a raw surface of a dull, dirty red colour. The mucous 

 and serous structures of the abdomen and also the muscular 

 tissues will be found more or less gangrenous. The great ner- 

 vous centres will be softened, attended with an efi'usion of serum 

 within the cavities of the brain, while the nervous substance 

 itself will be of a dirty white colour. The structure of the 

 heart will also be found to have lost its natural firmness, and 

 its cavities to contain blood in a semi-fluid state and of a black 

 green colour ; in fact, scarcely a single structure can be found 

 in a normal state — all appears to be afiected with gangrene 

 and disorganisation.
