SUNSTROKE AXD HKATSTKOKE. 



These are cerebral troubles: Sunstroke is ])iocluce(l 1)V the rays of 

 the sun fallin^^ directly upon the cranium. Heatstroke is caused l)y 

 the overheating; of the whole body or by excessive exertion. 



Symptoms. — vSunstroke is manifested suddenly; the animal stops, 

 drops his head, begins to stagger, the breathing is marked by great 

 snoring, the pidse is very slow and irregular, cold sweats break out in 

 })atches on the surface of the body, and the animal often dies without 

 recoveiing consciousness. 



In heatstroke the animal usually retpiires urging for some time pre- 

 vious to the appearance of any other symptom, (rcncnally ])ers])i- 

 ration is checked; he becomes weak in his gait; th(^ breatliing grows 

 hurried or panting; the eyes watery and bloodshot ; nostiils dilated 

 and highly reddened to a dark purple color; the judse is lapid and 

 weak; the heart bounding, frequently followed by unconsciousness 

 and death. Temperature reaches 107° to 112° F. If recovery takes 

 ])lace convalesence extends over a long period of time, (hiring which 

 locomotion shows lack of full control. 



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 2 ounces ai'omatic sj)irits 

 of ammonia or 4 ounces of alcohol in 8 ounces of water; r(^])eat in one 

 hour if necessary. Place the animal in a cool and sluuly ])lace, and 

 bathe the whole body with cold water until the tem])eriiture is lowered. 



Diseases of the Lymphatic System. 



Acute inflammation of the lymph gland usually occurs m connection 

 with some inflammatory process in the region from which th(^ lymph 

 is gathered. 



The lymph glands between the branches of the lower jaw almost 

 invariably become affected in strangles, nasal catajih (acute or 

 chronic), diseased or ulcerated teeth. Infected wounds of any ])art 

 of the body may cause inflammation of the neighboiiug lympliatlcs. 



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

 connective tissue surrounding them becomes involveil, suppuration 

 (formation of pus) usually takes place, and one or moie abscesses 

 form. If the inflammation is of a milder type the swelling may dis- 

 appear and the gland will assume its normal condition without sup- 

 puration. 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. 



Treatment. — Komentations with hot water will relieve the soreness, 

 unless an ab-scess is forming. If such is known to bo the case a poul- 

 tice of bran or flaxseed meal should be applied, and as soon as fluctua-
