Boil this mixture until it turns a deep orange 

 color and make up to five quarts, with water. Re- 

 peat the treatment in ten days. In mild cases it is 

 sufficient to clip the hair around the affected spot 

 and apply the above solution, or in sensitive situa- 

 tions like the eyelids or eyebrows, equal parts of 

 balsam of Peru and olive oil make a most satisfac- 

 tory substitute. Repeat the treatment every ten 

 days until a cure is effected. 



Follicular Mange 



Follicular mange is one of the most serious skin 

 diseases from which bur patients suffer, the parasite 

 being so deeply situated that parasiticides have no 

 permanent effect and bacterin treatment is effective 

 in only a few cases. 



Cause. — Follicular mange is caused by a parasite, 

 the Demodex folliculorum, which gains access to the 

 sebaceous glands and hair follicles and there multi- 

 plies. These parasites produce the characteristic 

 symptoms of the disease by the irritation they them- 

 selves create and by opening the doors for the in- 

 vasion of pyogenic organisms. 



Symptoms. — The disease exists in two forms, the 

 squamoiLs and the pustular. In the former the re- 

 gions affected are usually around the eyes, lips, 

 throat, breast, and legs, but it may extend to the 

 whole body. The skin becomes inflamed and cov- 

 ered with scabs and the hair falls out, leaving bald 

 patches. By gently scraping the parts with a blunt 

 knife and placing the debris so collected under the 

 microscope the parasite can be easily discovered.
