DISEASES OF DOMESTIC ANIMALS 617 



Warts. Verrucae. Papillomata. 



In young animals on the belly, prepuce, mammae, lips, eyelids, ears, 

 mouth and vagina (bitches); and about the fetlocks (grapes) in horses. 

 They should be removed by excision with scissors, or the Itnife. Torsion 

 and ligature are also employed. Strong acetic or nitric acid may be ap- 

 plied to small growths, but are not so certain as scissors and should never 

 be used about the mouth or eyes. Warty growths of the lids are apt to 

 become malignant and should be removed with a free elliptical incision; 

 also warts on the penis should be freely removed with scissors and their 

 base cauterized with strong nitric acid. The actual cautery may be em- 

 ployed, as in grapes. 



Weed. See Lymphangitis. 

 Whistling. See Roaring. 

 Wind Galls. 



This condition is a tenosynovitis and hygroma of the sheath of the per- 

 foratus behind the metacarpus. See Tenosynovitis. 



Wind-Sucking. Crib-Biting in Horses. 



Cover stable fixtures with metal and give so much work that vicious 

 habits will not be acquired. The use of a muzzle or spiked strap about the 

 larynx may sometimes prevent wind-sucking. Avoid any articles which 

 can be bitten; feed off the ground, or remove manger after feeding. Cut 

 hay and grain with an ounce of carron oil are indicated in tympany. Iso- 

 lation of wind suckers is advisable, to avoid acquisition of the trick by 



* other animals. 



Withers, Fistulous. See Fistula. 



Worms. See Parasites, Intestinal. 



Wounds. 



Simple Operative Wounds — The hair should bft shaven from the surround- 

 ing area. The simplest, and as effective as any method of skin sterilization 

 is the application of tincture of iodine to the dry skin, or the following may 

 be used. The skin should be washed with green soap and water, with 70 

 per cent, -alcohol and finally with pure ether or, better, Harrington's solu- 

 tion. The operator's hands should be cleansed likewise and covered with 

 rubber gloves. The wound should be handled as little as may be. All 

 hemorrhage must be arrested. If the wound is deep, it should be closed 

 by layers of buried catgut sutures, the skin by silk-worm gut sutures 

 (interrupted). Drainage should be avoided unless the conditions are very 

 unfavorable. Cover the wound with dry aseptic gauze and bandage. Secure 

 rest by splints if possible. Leave dressings in place for a week or two, 

 miless they become soiled and displaced. 



Accidental Wounds — If the wound is fresh, arrest hemorrhage by suture; 

 hot (or even boiling) water; ice water; actual cautery, in very vascular 

 or deep seated parts, using a dull-red heat; rubber tourniquet; acupressure; 

 pressure by fingers or hemostatic forceps; torsion; or chemicals — as adren- 

 alin solution. If hemorrhage not severe or after bleeding arrested, cover 

 wound with sterile gauze and shave or clip hair from surrounding area 

 without the use of water. Cleanse skin with gasoline or ether. Then remove 

 dirt from wound with sterile gauze or scissors and forceps, and also loose 

 tissue. Then apply tincture of iodine to wound and surrounding skin and 

 cover with dry sterile gauze. Or curette, scrub with gauze, and wash wound 

 with sterile salt solution for 15 minutes if soiled, and apply dry sterile gauze. 

 Recently a solution of dichloramine-T (5-7%) in chlorcosane has come into 

 favor as a primary and subsequent dressing in accidental wounds in prefer- 

 ence to iodine. Divided structures, as tendons, nerves and muscles, should be 

 sutured with sterile, iodized catgut. If the surroundings are favorable and 

 the wound can be bandaged, it should be closed as an operative wound 

 without drainage. If the wound is deep and the conditions unfavorable, 

 drainage by a sterile rubber tube placed into the deeper parts of the wound, 

 and the rest of the wound sutured— should be the rule. It is always easy
