234 TYPHOID PIfEUMONIA. 



mucous membranes of the organism generally. It also occa- 

 sionally associates itself with a form of disease closely resembling 

 Strangles. This, perhaps, is to be regarded as its most dan- 

 gerous association, inasmuch as the latter may entirely mask 

 the insidious operations of the former. 



When the disease has passed into its more malignant states, 

 the blood speedily becomes loaded with poisonous materials, 

 which the system will imbibe more or less ; and those struc- 

 tures requiring the most blood to properly and efficiently 

 continue their healthy function, (and which in themselves are 

 the most vascular,) will, as a matter of course, speedily become 

 participators in the morbid change. Thus we frequently find, 

 in this disease, that the patient will exhibit symptoms of abdo- 

 minal disease of a very low or sub-acute character ; the animal 

 will occasionally regard his side anxiously ; sometimes he will 

 paw the ground and lie down, and when down he is seldom or 

 ever violent. As the disease becomes more confirmed, the 

 animal is afi'ected with purging, and the fseces are mixed with 

 black semi-fluid blood, from which is emitted a most intolerable 

 stench. 



Pathogis^omois'IC Symptoms. — Tlie excessive general delility 

 of the 'patient ; the faint, suffocative cough ; the tremulous state 

 of the slcin, and siib-textures covering the chest ; the rales within 

 the windjpipe and hronchial tubes ; and, ahove all, the presence 

 of a peculiar cadaverous ejffluvium from the hody of the patient, 



Peogistosis. — We must be guided in our prognosis by the 

 nature of the attack, by the character of the pulse and the 

 respirations, by the appetite, and the debility. If the attack be 

 mild — if the pulse becomes reduced in the number of its 

 beats, accompanied with a corresponding decrease of the respi- 

 ratory acts — if the appetite is restored, and the animal lies
