DISEASES FOLLOWING PAETtTEITION. 227 



Iced water or bags of ice to the head (tied around the horns and 

 covering the forehead and upper part of the neck) are of the very 

 greatest value in cases in which the heat of the horns, ears, and head, 

 the redness of the eyes, and fixed dilatation of the pupils are marked 

 features. Like bleeding, it may be uncalled for in those cases in 

 which the heat and general congestion of the head are absent. 



In these congestive cases, too, benefit is often derived from large 

 and frequent doses (20 drops every four hours) of tincture of aconite. 

 It acts not alone as a sedative to the heart and circulation, but also by 

 favoring a free circulation in the skin. In what may be called the 

 noncongestive cases it is of little avail. 



Harms claims excellent results from large doses of tartar emetic — 1 

 ounce for the first dose, 3 drams more after four hours, and 2 drams 

 after four hours. If absorbed it will act after the manner of aconite 

 as a sedative by causing a free circulation in the skin. 



This increased circulation in the skin serves to draw away blood 

 from the internal organs, and thus to relieve the brain, and to secure 

 the same result a variety of resorts are had with varying success in 

 different eases. ,The application of hot (almost scalding) water to the 

 back and loins, or to the limbs, acts in this way. So do mustard plas- 

 ters, frictions with oil of turpentine, the prolonged movement over the 

 part of a hot smoothing iron with a thin cloth between it and the skin, 

 or finally the application of strong liquor ammonia, covered up for 

 fifteen minutes with a close rug. 



In cases with a high body temperature an excellent plan is to wrap 

 the whole body in a blanket slightly wrung out of cold water, and cover 

 this closely at all points with dry blankets to exclude the air and pre- 

 vent evaporation and cooling. In fifteen or twenty minutes a reaction 

 will have taken place, the whole body will have been cooled somewhat 

 by the blood returning from the skin since the blanket was applied, and 

 the free perspiration will now serve to relieve both by cooling and by 

 carrying off waste matters from the blood. This may be repeated sev- 

 eral times a day if the temperature rises again. In cold weather the 

 skin should be rubbed dry on each occasion. 



A similar method of drawing off the blood from the brain is by fre- 

 quent rubbing of the udder and drawing off the milk. 



In case of extreme prostration and weak pulse one-half ounce car- 

 bonate of ammonia may be given, and repeated at the end of an hour 

 or two if needed. It may be given as a roller-formed bolus made 

 up with a very little flour to give it consistency, or if the cow can not 

 swallow, it may be dissolved in water and poured through a probang 

 (PL III, fig. 2), or tube, introduced into the stomach. 



Bloating of the left side (paunch) is a common and dangerous com- 

 plication of the disease, as it at once aggravates the pressure on the 

 brain, partly by expression of blood from the abdominal organs and 

 partly by nervous action through the vagus and sympathetic nerves.
