104 THE ARMY HOESE. 



The dressings must be of a caustic nature, so as to destroy' the 

 cause of the disease; for instancei, alcohol 4 ounces, salicjdic 

 acid 1 ounce, bichloride of mercury 2 drams; alternate this 

 with a dressing made of equal parts of olive oil and creolin. or 

 one made of tincture of iodine 2 ounces and tincture of iron 2 

 ounces. Apply any of these dressings once daily and then use a 

 dusting powder made of equal parts of iodoform and tannic 

 acid. 



Care should be exercised to isolate the diseased animals and 

 to thoroughly disinfect combs, brushes, blankets, halters, and 

 such articles as may have come in contact with the diseased 

 parts; for this purpose use a 1 to 20 solution of creolin or of 

 carbolic acid. 



DHOBIE ITCH. 



This is a very troublesome skin disease peculiar to the tropics. 

 It is contagious and caused by a fungus. 



Symptoms. — Itching, the animal rubbing against the posts 

 and sides of the stall ; small eruptions of the skin, which spread 

 rapidly and discharge a thin, water}^ secretion, crusts forming 

 over the sores ; the hair falls out and the skin becomes thickened 

 on account of the irritation. Often the skin of a large part 

 of the surface of the body becomes infected with these sores, 

 and ordinary healing washes have no beneficial action. The 

 treatment, like that of epizootic lymphangitis, should be 

 prompt and energetic, and. since both diseases are caused by a 

 fungus, should be similar in nature. One of the most valuable 

 remedies is made of equal parts of olive oil and creolin. which 

 should be applied once daily after thoroughly washing the 

 sores and removing the scabs. A mixture of alcohol 6 ounces 

 and salicylic acid 1 ounce is of value and is applied dailv. In 

 the absence of alcohol, sulphuric ether may be substituted. 

 Tincture of iodine often eifects a cure. If the case is persist- 

 ent, cauterize the parts with pure carbolic acid and then apply 

 klcohol after the acid has been on one minute. After cauteriz- 

 ing use the olive oil and creolin dressing daily. 



On account of its contagious nature, all animals sulfering 

 from tliis disease should l)e isohited, and brushes, combs, 

 bhmkets, etc., should l)e thoi-oughly disinfected with creolin or 

 carbolic acid solution. 



The common diseases of temperate countries assume a more 

 aggravated form in the tropics. Infectious diseases are more
