Symptoms. — The premonitory symptoms of this com- 

 plaint are loss of appetite, with depression and an 

 appearance of anxiety ; rapidity of breathing, and 

 consequent increased motion of the flanks, accompanied 

 by a hard, dry, short cough. The pulse at first is full 

 and oppressed, thereafter quick and small, and difficult 

 to be felt. The mucous membrane Iming the eyelids 

 is considerably congested, and sometimes approaching

 and the horns, ears, and legs are generally cold. 



Cause. — This complaint is caused by sudden 

 changes of temperature, or by removing the animals 

 from close, sheltered situations, to exposed, high, and 

 cold localities. Cattle feeding in low and damp 

 situations, exposed to dense fogs and moist atmos- 

 pheric changes are liable to be affected with inflamma- 

 tion of the lungs. Suddenly checking the perspiration 

 by drinking a large quantity of cold water, when the 

 animal is subjected to a high temperature, is another 

 frequent cause. From this it will be manifest that 

 sheltered sheds will be most beneficial in the feeding 

 of cattle, either to retire into when exposed to the 

 meridian of a summer sun, or during rains. It will be 

 seen that in either case cattle will invariably avail
