Treatment. — Clip the hair from the parts and use the zinc 

 lead and acid lotion. It is a mistake to nse powerful remedies at 

 first. Carbolic acid in its undiluted state should be applied 

 thoroughly to the parts, and the zinc and lead lotion used for a 

 few days, when the acid should be applied again as stated before. 

 It should never be used more than twice in its undiluted form. 

 Charcoal should be used to destroy the odor. Solutions of car- 

 bolic acid, one to sixteen, may be applied for this purpose. When 

 grapes are present they should be removed by the actual cautery, 

 it being more effectual than caustics. To do this requires two 

 irons, one hot and the other cold. The cold iron is to be placed 

 so as to protect the healthy structures, while the hot one removes 

 the grapes. A very useful apj)lieation to greasy and cracked 

 heels is found in the benzoated oxide of zinc ointment. It may 

 result in ulcers at the heel, which should be removed by caustics, 

 such as caustic potash and poultices. The constitutional treat- 

 ment consists of eight drachms of aloes, given at the outset of 

 the disease, and when the cathartic acts, give arsenic and iron — 

 five grains of arsenic to two drachms of sulphate of iron. Give 

 twice a day in feed. 



RAT TAILS. 



This is an inflamed condition of the dermis. There is an exu- 

 date, the papillary layer of the skin becomes enlarged, showing 

 transverse ridges resembling rat tails. It is generally seen in 

 the hind limb, and is a result of grease. 



Treatment. — Purgative, and use the zinc lead and acid lotion 

 externally. 



CRTJSTA lABIALIS. 



This is an eczematous condition, and is said to be due to the 

 actions of grasses in the pastures. I am inclined to think that it 

 is caused by some derangement of the digestive organs. 



Treatment. — Use the carbolic acid lotion, or the zinc lotion, 

 or lead lotion. They are all good remedies.
