104 THE PRACTICE OF VETERINARY MEDICINE. 



Treatment. — Wash the parts well with soap and water, 

 after which apply the following ointment : lodi, potass, 

 iodi., cljl. 5i., adeps 5vi. — 5i, ; or in some cases the parts 

 may be touched with argenti nitras. Touch pretty freely, 

 and then use the unguentum iodi. After handling the 

 patient, the hands should be washed to obviate the danger 

 of contracting the disease. In case the animal is debilitated, 

 the use of tonics is indicated, as iron, arsenic, etc. A solu- 

 tion of argenti nitras is sometimes used as an application, 

 in the proportion of argent, nit. grs. x. — xx. aquae, O.i. 

 Carbolic acid lotions are always good and safe, except in the 

 case of the dog. The clothing of the affected animal 

 should also be saturated with some lotion calculated to 

 kill any parasites it may contain. Honeycomb ringworm is 

 treated in exactly the same way. 



Lousiness. — Lice in veterinary practice are of two kinds 

 — first, the ordinary horse-lice, invited by a filthy condition 

 of the animal, improper grooming, debility, etc. ; secondly, 

 poultry lice. These latter are smaller than the equine 

 louse. Lice also affect the other animals, as cattle, etc., 

 destroying fine coats, causing unthriftiness, etc. 



Symptoms. — The presence of either variety of lice is 

 easily detected. Considerable irritation is manifested by 

 the animal scratching himself, a staring coat, a mangy 

 appearance, and an unthrifty look generally, the itching 

 seeming to be more severe about the root of the tail, 

 mane, etc. ; and on making a close examination, the para- 

 sites may be detected swarming over the body of the 

 animal. Poultry lousiness is by no means unfrequent in 

 horses standing near hen-houses. Sometimes the irritation 

 of poultry lousiness is so great as to cause the animal, 

 when tied, to break loose to scratch himself. The mane 

 and tail fall out, and even slight inflammation may exist. 



Treatment. — One of the best applications known for the
