DISEASES OF THE SKIN. 331 



tufl.d or club-shaped, occasionally existing as thick, short, fleshy 

 excrescences, giving the growth the appearance of granulation tissue. 

 Their color is red or purplish, and oftentimes by friction they become 

 raw and bleeding, emitting then a very offensive odor. They usually 

 grow in clusters and their development is rapid. 



Causes. — An abnormal nutrition of the skin, determined by increased 

 energy of growth operating upon a healthy skin ; at other times, upon 

 a weak or impoverished skin. 



Treatment. — When they are small and pedunculated they may be 

 snipped off with shears, and the stump touched with nitrate of silver. 

 When they are broad and flattened they can be dissected out, and the 

 wound cauterized, if necessary. If they are large and very vascular, 

 they may be ligated, one by one, by taking a strong cord and tying it 

 as firmly around the base as possible. They will then shrivel, die, and 

 drop off. If there is a tendency to grow again, apply a red-hot iron, 

 or nitric acid with a glass rod. Very often warts willquickly disap- 

 pear if they are kept soft by daily applications of sweet or olive oil. 



KBLIS. 



Kelis is an irregularly shaped flat tumor of the skin, resulting from 

 hypertrophy — increased growth of the fibrous tissue of the corium, 

 producing absorption of the papillary layer. 



Causes. — It may arise spontaneously, or follow a scar ^fter an 

 injury. 



Symptoms. — Kelis generally appears below the knee or hock. It 

 may occur singly or in numbers. There are no constitutional symp- 

 toms. Its growth is very slow and seldom causes any inconvenience. 

 It appears as a flattened, irregular, or spreading growth within the 

 substance of the skin, is hard to the touch, and is -especially charac- 

 terized by divergent branches or roots, resembling the claws of a crab, 

 and hence the name. Occasionally some part of it may soften and 

 result in an abscess. It may grow several inches in- length and 

 encircle the whole limb. 



Treatment. — So long as it causes the animal no inconvenience it is 

 best not to meddle with it; when it does, the animal ought to be fat- 

 tened for beef, the meat being perfectly harmless to the consumer.
