water; before using the lotion, wash the cracks with soap and water and 
gently dry the heel. In the absence of much inflammation, the disorder not 
being an outgrowth of constitutional disease, apply morning and evening 
a liniment of one drachm of liquor arsenicalis to one ounce of glycerine. 
When the inflammation is not very active, good results may be secured by 
a dry flannel bandage applied moderately tight around the leg. Give 
arsenicum three times a day, Put on high-heeled shoes, and give two 
hours in walking exercise daily. Exercise care during coating. 
MANGE.—ITCH. 
This is an itching and scaling of the skin from the presence of para- 
sites under the surface. It is caused by a poor and weak condition, with 
want of cleanliness. It is contagious, though it is seldom transmitted to 
strong, well-kept horses, and then does not spread among them. 
Symptoms.—Itching, secon followed by falling of hair and scaling of 
skin; small vesicles form on the skin, burst, and discharge a fluid which 
forms into a scab; this being removed, the microscope detects very small

becomes raw and ulcerated by repeated rubbing; in advanced stages fever 
appears, with loss of flesh and sometimes dropsical indications. The neck,

attendant may take the itch by contagion. 
TREATMENT.—Give arsenicum night and morning in cases with 
scabby sores and red, burning ulcers, with hard-crusted edges. It is valuable 
when the horse is in low condition. Mercurius is needed if there be raw 
sores or pustular formations. To destroy the parasites, use the above inter- 
nal remedies and in addition put on the affected parts and thoroughly rub in 
a liniment composed of three ounces of oil of tar and one pint of train oil, 
first carefully washing the parts with soft soap and warm water, and drying 
with care. Repeat the process in three or four days. Three ounces of 
sulphur and a pint of oil make a good ointment. Carbolic acid, one part
