feverish eye, pale and slimy nostrils and inside of mouth, — or 

 generally the appearance that tells a person accustomed to stock 

 that an animal is not alto^^jether right. 



In dairy cows, again, without or along with any of the above 

 symptoms' in a more apparent degree, may also be observed a 

 decided and unaccountable deficiency in the yield of milk, tender- 

 ness of the teats, a refusal of food, or any change in their 

 customary habits or behaviour. 



In this stage, generally speaking, beyond the symptoms of fever, 

 no decided post mortem appearances are discernible ; but in some 

 few instances there may be found congestion and inflammation 

 of portions (generally the points) of the lungs, or of either of them, 

 and inflammation of the pleurae, with eff'usion of lymph on the 

 inside of the i-ibs and diaphragm. 



Second Stage. 



Tlie symptoms here in bush cattle, — in addition to those of the 

 first stage in an aggravated form, — may be all or any of the fol- 

 'lowing, namely, a stiifness in the fore-parts, a decided disinclina- 

 tion to move, a drawn-up and cramped appearance when standing, 

 especially noticeable to the practised eye at a distance, a sudden 

 and almost instantaneous stopping on being allowed to do so in 

 driving, a hard, sharp, and frequent cough when moved out of 

 a slow walk, and sometimes even when standing, with now and 

 then a discharge of frothy phlegm from the mouth, a heaving of 

 the sides, and decided symptoms of atfcction of the lungs, the 

 nostrils inflamed and filled with slime, and the muzzle covered 

 with drops of clear moisture, the eye protruded, feverish, and 

 watery, a rapid falling off in condition, or a disinclination in the 

 animal to lie down, and when it does it rests on the afl'ected side. 



In milch cows the more noticeable symptoms of the second 

 stage of the disease, in addition to those given, are sometimes a 

 sudden purging, a falling ofl"in the quantity of and a yellowish tinge 

 in the milk, want of appetite, especially for green food, difficulty 

 in swallowing, apparent thirst, grunting while turning in the stall, 

 or tenderness under pressure along the back and loins. 



A post mortem examination of an animal in the second stage of the 

 disease will in most cases show a small quantity of fluid of a bloody 

 tinge in the cavity of the chest, effusions of lymph on the insides 

 of the ribs, pleura?, and the diaphragm ; great inflammation of the 

 pleurfe, and sometimes attachment of the lung to the ribs. But 

 the chief and unmistakeable symptom of this stage of pleuro- 

 pneumonia is to be found in the lungs. At this stage of the 

 disease a portion of each of the lungs, or what is more frequently 

 the case, from a third to three-fourths of one lung, — generally the 

 right — is hepatized, or (what is commonly called) "marbled," 

 while the rest of the lung is only partially hepatized or congested,
