706 GENEBAL THERAPEUTIC MEASURES 



invigorates the failing digestive functions, relieves the nerv- 

 ous irritability by cooling the blood going to the great nerve 

 centres in the medulla, and strengthens and stimulates the 

 entire nervous organization. Cold applications -and drinks 

 stimulate the circulation reflexly, increase blood tension, and, 

 therefore, the secretion of urine in fever, which is very im- 

 portant for the elimination of toxins. Locally, heat and 

 cold are often used interchangeably in medicine. In human 

 practice it is a rule to be guided in the choice of one or the 

 other by the desire of and effect upon the patient, and this 

 should apply, as far as possible, in veterinary practice. 

 Cold is employed, locally, in congestions of superficial parts, 

 and tends to abort inflammation and relieve pain. 



lu meningitis, rubber ice bags or continual irrigation of 

 the head and spine are used. Laryngitis may be success- 

 fully treated by ice poultices (cracked ice and sawdust iu 

 linen bags) or by thin rubber ice bags surrounding the 

 throat. In the same way are treated sprained tendons, 

 capped hocks, broken knees, recent curbs, and lymphangitis. 

 In fact, most superficial inflammatory surgical affections are 

 benefited by cold applications. Ice and ice water are useful 

 in checking venous or capillary haemorrhage, although hot 

 water is often more serviceable. Cold water enemata are 

 valuable in atonic constipation, diarrhoea, and to reduce 

 temperature in fever. Iu the uterus, ice in small lumps 

 will arrest metrorrhagia, and, in the rectum, aid in reducing 

 prolapse. Ice bags, placed along the spine over the sym- 

 pathetic ganglia, will cause dilatation of arterioles in regions 

 corresponding to the point of application. 



MODES OF EMPLOYING COLD WATER.* 



Ablution is the simplest method of applying water to the 

 surface of the body. It is merely bathing. Water at the 

 temperature of 50° to 60° F. is applied by a rough, coarse
