SKIN DISEASES. 



FALLING OFF OF THE HAIK. 



Theee are a number of skin diseases which cause the falling 

 off or destruction of the hair. Some of them are described 

 elsewhere. The disease I propose considering here occurs in 

 two forms : the one called humid or moist exanthema, and the 

 other dry exanthema. The disease is first noticed in the form 

 of little blisters, or vesicles, which pour out a fluid that dries 

 u}), leaving hard scabs, which are replaced by small ulcers, that 

 finally deepen into the skin to such an extent as to destroy the 

 roots of the hair. Very great itching attends the disease, 

 causing the horse to rub himself severely, even rubbing the 

 hair off. It may appear on the neck, flanks, or sides, and ex- 

 tend from these points. The horse's coat may be extensively 

 destroyed by this disease. 



The dry form of the disease appears in pimples, which dry 

 up, leaving a bran-like scurf. The itching in this form is also 

 very great. 



Treatment. — The affected parts of the body should be washed 

 every day with soap and water, very thoroughly. Then an 

 ointment, made as follows, should be carefully applied to all 

 the sore parts : 



Take— -Pyroligneous acid 6 ounces. 



Charcoal, powdered 2 ounces. 



Olive oil 1 pint. 



Common salt 1 ounce. 



Resin, powdered 2 ounces. 



Mix^ to form an ointment, to be used once a day.
