Symptom fi. — Sunstroke is manifested suddenly; the animal 

 stops, drops his head, begins to stagger, the breathing is marked 

 by great snoring, the pulse is very slow and irregular, cold 

 sweats break out in patches on the surface of the body, and the 

 animal often dies without recovering consciousness. 



In heat exhaustion the animal usually requires urging for some 

 time previous to the appearance of any other symptom. Gen- 

 erally perspiration is checked, he becomes weak in his gait, the 

 breathing grows hurried or panting, the eyes watery and blood- 

 shot, nostrils dilated and highly reddened to a dark i^urple color, 

 the pulse is raiDid and weak, the heart bounding, followed by 

 unconsciousness and death. If recovery takes place convalesence 

 extends over a long i)eriod of time, during which incoordination 

 of movement may be present. 



Treatment. — The treatment consists in the application of cold 

 in the form of ice, or cold water on the head, cold injections per 

 rectum, and the administration of stimulants, such as 1 ounce 

 carbonate of ammonia with 2 ounces alcohol; repeat in one hour 

 if necessary. Place the animal in a cool and shady place. 



Diseases of the Lymphatic System. 



Acute inflammation of the lymph gland usually occurs in con- 

 nection with some inflammatory process in the region from which 

 the lymph is gathered. 



The l\Tnph glands between the branches of the lower jaw 

 almost invariably become affected in strangles, nasal catarrh 

 (acute or chronic), diseased or ulcerated teeth. Similar results 

 obtain in other parts of the body. 



Symptoms. — The glands swell and become painful to the touch, 

 the connective tissue surrounding them becomes involved, sup- 

 puration usually takes place, and one or more abcesses form. If 

 the inflammation is of a milder type, the swelling may disappear 

 and the gland will resume its normal condition without suppura- 

 tion. The temperature will be elevated. Sometimes the glands 

 will remain hard and considerably swollen for some length of 

 time. In man these swollen glands are known as kernels. 



In tropical countries Ijnnph glands are very liable to become 

 inflamed and diseased; suppuration rapidly follows, the gland 

 will open, discharge its accumulation of pus, and the open sore 

 so formed will be healed with the greatest difficulty.
