EETJPTIONS. 203 



Causes. — This affection commonly arises from gross feeding. 

 Beans are occasionally productive of it. I have also known it 

 to arise from the animal working a considerable time in wet 

 clay. Want of cleanliness is another cause. The skin in 

 these cases should be examined for Acari. 



Treatment. — Attention in the first place must be directed 

 to the diet, and to the cleanliness of the animal. Take away 

 the beans. 



If the disease proceeds from the patient working in clay, 

 the animal had better be removed from its influence ; but if 

 that cannot be done, the affected limbs should be protected. 



I have not been able to prescribe anything more efficacious 

 for this purpose than rubbing upon them (just before the 

 animal goes to labour) a quantity of Palm Oil, or a mixture of 

 Palm Oil and Tallow ; or, if the Palm Oil cannot be readily 

 procured, use the Tallow alone. Either of these substances 

 will for a certain time, if liberally applied, prevent the dele- 

 terious action of the clay upon the limbs. 



The best remedies for this affection in general are Arseni- 

 cum 3, Phosphoric Acid 2, and Sulphur. 



Unless beans are withheld from the animal affected, and the 

 extremities kept clean, medicine will seldom prove of much 

 avail, especially if the patient be predisposed to the disease.

A third condition under which Surfeit exhibits itself is that 

 of an eruption upon the skin, which may be either local or 

 general. 



Two varieties of this affection are occasionally manifested 

 which appear under somewhat different circumstances, run a 

 different course, and terminate in a different manner. Both 

 varieties, however, have this in common, — they usually exist
