252 THE PEA.CTICAL HOUSE KEEPER. 



This condition is usually brought about by derangement of 

 the stomach, or it may be due to exposure to a hot sun, cold 

 wind, standing in draughts when over-heated, or from the 

 horse drinking cold water when hot. 



The treatment will depend upon the cause. If surfeit 

 arises from indigestion, a mild dose of physic with sloppy diet, 

 with an ounce or two of bicarbonate of soda once or twice a 

 day in it, will effect a cure. If the eruption becomes chronic, 

 tonic medicines should be given. The body should be well 

 clothed. 



A constitutional form of surfeit is sometimes seen, and is

 burst and crust over ; and at the same time there is great 

 itching, causing the horse to rub and bite himself. 



Great attention should be paid to the diet, which should be 

 more or less laxative, and nitrate of potass should be frequently 

 given. Liquor arsenicalis is useful mixed with the food about

Active treatment is necessary for the destruction of the 

 parasite. Paraffin oil, applied once a day, and allowed to dry 

 on the skin, is very efficacious, as is also a mixture of sulphur 

 and common oil, well rubbed into the skin ; or oil of tar 

 and sulphur, of each two ounces to a pint of common 

 oil. McDougall's sheep-dip, also Jeyes' fluid, may be 

 used advantageously. The skin should be washed with 

 soap and water before the dressing is applied, and it should be 

 washed again in a day or two after the dressing. Clothing and
