CONGESTION OF THE SKIN. 



Simple redness, heat, and tenderness with no dark colour or 

 eruption. This may coexist with all the different forms of 

 inflammatory eruption according to the degree of irritation at 

 different points. 



It occurs : From chafitig, in the axilla, between the thighs, 

 in the heels or under the harness in hot weather ; from chills 

 after being wet, in the heels of horses and on the teats of cows 

 exposed to wet in winter; from hardened fnud in the space 

 between the hoofs in cattle, sheep, and pigs ; and from the

 laxatives, diuretics, or tonics must be used according to the 

 indications. It is all-important to avoid further irritation.

 very serviceable. So too, must exposure of affected heels to 

 damp or mud, and the wetting of teats in milking, be carefully 

 avoided. 



CONGESTION WITH SMALL CONICAL PIMPLES. PAPULES. 



In this case there is an eruption of finely-pointed pimples 

 without any watery exudation or blister. It is usually itchy and 

 even painful, and by reason of rubbing may go on to exudation 

 with great thickening of the skin, bleeding, scabs, and open 

 sores. Horses, especially, suffer in spring and autumn at the 

 time of shedding the coat, the eruption often confining itself to 

 the neck, shoulders, and limbs. On turning back the hair on
