severe on parts devoid of eruption, jet the integument 

 tends to become tliiekened and rigid as the disease per- 

 sists. The irritation may be shght or so severe that the 

 harness cannot be kept on. It must not be confounded 

 vith rubbing of the tail from pin-worms. 



Treatment. Purge, put on restricted diet, with roots 

 wash the skin with soap and water, and apply water 

 slightly soured with oil of vitriol. If this, with carbonate 

 of soda internally, fails to cure, a long course of arsenic is 

 demanded. 



WAETS. OAliLOSITIEa. CANCEE. BLACK PIGMENT TUMOES. 



Waets are to be removed by scissors and the part burned 

 with some caustic (lunar caustic if near the eye, butter of 

 antimony, blue-stone, chloride of zinc, etc., elsewhere). 

 Or they may be destroyed by tying a thread tightly round 

 the neck of each, or by the use of the hot iron. 



CAiiOsiTTES are common under the saddle (sitfasts). A 

 circumscribed portion of skin, the seat of a former chafe, 

 has become thickened and indurated to almost horny con- 

 sistency. The skin around the edges is inflamed, raw 

 and angry. It can usually be loosened by a poultice, so 

 as to be easily removed by a sharp knife, after which it is 

 to be treated as a common sore. 



Black Pigment Titmoes (Melanosis) are exceedingly 

 common in gray and white horses, attacking the black 

 parts of the skin (anus, vulva, udder, sheath, hps, eyehds, 

 etc.,) and though sometimes cancerous are often quite 

 harmless, and should always be removed with the knife. 



Epithelial Cancee is not common in the lower animals 

 but is seen in the lips of horses and cats. Here again the 

 knife is the best remedy. 



PABASITIC DISEASES OF THE SKIN.

 This is common in horses, cattle, dogs and cats, as well 

 as in man, and is readily transmitted from one to the
