Other delicate parts of the skin (vulva, etc.), and pigs and dogs 

 on any part of the body. 



Causes. — It is often chargeable on some disorder of digestion 

 as the result of unwholesome food or a sudden change of food, 

 as from dry to green, or from one kind of pasturage to another. 

 In young animals (foals, calves, lambs, kids, pigs), it appears to 

 be an occasional result of heated or otherwise unwholesome 

 milk. Vetches affected with honey-dew have produced it in 

 white horses or in white spots of those of other colours ; and 

 buckwheat has affected white sheep, pigs, goats, etc., in the 

 same way. It may, liowever, arise from habitual exposure to 

 cold and wet, local irritation, as from rubbing, etc., or from 

 disorder of other internal organs. 



Treatment consists in softening the crusts with oil, washing 

 them off with soapsuds, and applying soothing or gently astrm- 

 gent agents to the part (spermaceti and olive-oil, benzoated 

 oxide of zinc ointment, lime-water, sugar of lead lotions, etc.) 

 When it attacks the root of the mane cut off the hair, and if the 

 pain is excessive foment or poultice until the eruption comes 

 to a head, when some of the above agents may be applied. 

 When the pustules have burst and show little tendency to 

 healing, this may often be hastened by touching the sores with 

 a pointed stick of lunar caustic, or a weak solution of this 

 agent (2 grs. to i oz. water) may be lightly painted over tlie 

 part. The internal treatment consists in the administration of 

 laxatives followed by bitters (gentian, quassia, boneset, cas- 

 carilla, willow bark, etc), and diuretics. In obstinate or long- 

 staiiding cases the same treatment may be followed as in 

 chronic eczema. 



IKFLAMMATION OF THE HEELS IN HORSES. GREASE. 



The skin in the region of the heel is so vascular and so 

 abundantly provided with oil-glands, and is so frequently 

 exposed to irritants, wet, cold, mud, filth, etc., that a special
