day in his feed, and gradually bring him back to his natural feed 

 and work again. 



INFLAMMATION OF THE LUNGS (PNEUMONIA). 



This disease is inflammation of the lung substance itself and 

 is quite a common disease. The lungs in their natural state will 

 float on water. In the first stag^e of this disease the lungs are 

 filled with blood and serum, and they are of a dull reddish 

 color ; at this stage, if the animal dies, the lungs will still float on 

 water. As the disease runs on, if not cured, the lungs change to 

 a dark, grayish appearance ; if the animal dies and the lungs are 

 put in water they will sink. 



Causes — Are much the same as those of congestion of the 

 lungs and generally come on horses kept in a poorly ventilated 

 stable, which has a tendency to weaken the lungs ; sudden changes 

 in the weather, such as we have in the fall and spring, are liable 

 to bring the disease on. It is also sometimes caused by keeping 

 a horse in a warm stable and then turning him out to pasture to 

 lie on the cold ground ; or, if while he is out, a cold rain storm 

 comes on and he gets wet and is chilled through ; or, if a horse is 

 clipped and exposed to the cold ; standing in a draft while warm ; 

 inhaling smoke ; also by driving against a cold wind too soon 

 after he has had influenza, distemper, or any of those weakening 

 diseases. It also frequently follows congestion of the lungs. 



Symptoms. — Are much the same as congestion of the lungs, 

 only plainer. There is, generally, very little trouble in telling the 

 disease. It commences first by the animal shivering, after the 

 shivering ceases heat takes place ; the ears and legs will first be 

 hot and then cold ; the mouth is sticky and the breathing aff'ected, 

 but not so much as in a pure case of congestion of the lungs ; the 

 pulse is quick, ranging from fifty to seventy-five beats to the 

 minute, which is stronger than in a case of congestion ; the horse 

 does not care to eat ; stands up all the time, with head hanging 

 down and ears lopped over, and in hot weather perspires freely 

 around the chest ; the eyes have a glossy appearance and, around 

 the inside of the evelids, are very red. As the disease passes on 

 the horse breathes heavier and sometimes is noticed to sigh, as if 

 in distress ; the bowels become costive, ana the manure has a 

 glossy appearance; placing your ear to tne side of the chest you 

 will hear a grating sound similar to that prouuced by taking some 

 bair of *'our head, just above the ear. ancJ grating it between th«
