DISEASES OP THE SKIN. 



I. SIMPLE ECZEMA. 



-II. CHRONIC ECZEMA, OR PSORIASIS. III. ERYSIPELAS. 



I. Simple Eczema. 

 This is ji skill disease in which crops of vesicles come up, burst, run 

 a little watery matter, dry up and heal, but while these are healing an- 

 other crop breaks out in another place. It is attended with intense itch- 

 ing, which worries the animal exceedingly. 



What to do. — Give a purgative, No. 8, repeating it after a week ; also, 

 a change of food and good care. Let the cattle have salt at least twice 

 a. week. Bathe the affected parts frequently with lotion No. 47. 

 n. Chronic Eczema, or Psoriasis. 

 When simple eczema is neglected the disease becomes chronic. The 

 skin thickens, gets hard, dry and sore, and cracks into fissures or fur- 

 rows ; the discharge continues and be- 

 comes greasy, offensive and ichorous ; 

 and the hair gets thin and stands 

 straight out, or perhaps turns the 

 wrong way, giving the parts the ap-. 

 pearance of rat tails, by which name 

 the disease is often known. It is very 

 troublesome, frequently causing lame- 

 ness, and always proving hard to cure. 

 What to do. — Apply hot linseed 

 meal poultices to the affected parts till 

 all inflammation and soreness are 

 gone ; then embrocate freely with lo- 

 tion No. 9, using a cotton bandage 

 wet in the lotion and applying it loosely. If there are any points of 

 proud flesh, burn them down daily with lunar caustic. When all sore- 

 ness is gone and the disease appears to be under entire control, apply 

 either of the ointments Nos. 52 and 58. 



CHRONIC ECZEMA, OR 'UlAT TAILS," 



III. Erysipelas 



This is a diffuse inflammation of the whole th 

 sometimes extending to the subcellular tissue, ai 



(kness of the true skin, 

 il causmg much pam and 



irritative fever.
