COLD AND HEAT 679 



Local Baths are good, especially in inflammatory condi- 

 tions of the feet in horses. Tubs may be employed for the 

 animals to stand in, the water being changed frequently or 

 being kept cool by ice. It is not advisable to allow animals 

 to stand in large bodies of water on account of the danger 

 they incur of " catching cold " from surface evaporation. 



h^rigation with cold water is done in inflammatory dis- 

 eases of the joints, tendons and feet. Running water may 

 be permitted to flow continuously through perforated rubber 

 tabes, connected with a tap, or used as siphons and closed 

 at their distal extremities. The holes may be made in the 

 tube with red-hot needles. The rubber tubes should be 

 wound nbout the limb or part and held in position by band- 

 ages. Leiter's expensive block tin tubes are easily bent and 

 rendered useless by the movements of our patients. 



Cold Drinks are both refreshing and antipyretic in action. 

 Cool water should be placed where the patient can take it 

 as he desires. In stomatitis, tetanus and angina, cool water 

 is distinctly grateful and comforting. In the latter two dis- 

 eases, it should be arranged so that the animal can reach it 

 without bending the neck. The mouth can be rinsed out 

 continually, removing decomposing food and mucus, the 

 thirst be slaked and heat and inflammation relieved. 



Cold Enemata are valuable antipyretic agencies. From 

 five to fifteen quarts of cold water may be thrown up through 

 a flexible rubber tube, six feet long, far into the bowel of 

 the horse. 



Evaporating Solutions. — Methylene bichloride or ether 

 spray may be applied for a short time by means of an 

 atomizer, to induce local anaesthesia of a part, through the 

 powerful refrigeration produced in their evaporation, and is 

 most satisfactorily employed in conjunction with cocaine 

 injections. One turn of a cotton or linen bandage, or a 

 single thickness of similar stuff, put about a part and wet 

 continuously with cold water, forms a good evaporating 

 medium in allaying superficial inflammation and pain. A 

 mixture of clay, and equal parts of water, vinegar and diluted
