DISEASES OF THE EAR. 355 



Treatment. — The whole tumor or diseased structure should be cut 

 away, and the wound treated daily with a dressing of carbolized cos- 

 moline or turpentine and sweet oil, 1 part of the former to 4 of the 

 latter. 



FOREIGN BODIES IN THE EAR. 



Bugs have been known to gain entrance into the ear of an animal. 

 I once removed an acorn from the ear of a cow that had been roaming 

 in the woods. Accidentally, pieces of wood from a stanchion may 

 become lodged in the ear. 



Symptoms. — A continuous uneasiness or frequent shaking of the 

 head, occasionally the manifestations of exceeding great pain. The 

 animal may rub the head and ear against trees or other objects in an 

 endeavor to dislodge the offending body. 



Treatment. — A careful examination will reveal the offending cause, 

 which may be removed with a pair of forceps or scraped out with a 

 hairpin or piece of wire bent at one end. If much inflammation exists, 

 the ear may be swollen so that the foreign substance will be hidden 

 from sight; then a probe maybe inserted to feel for the object, which, 

 when located, should be removed, even if it becomes necessary to 

 split the ear at the base to do so. Afterwards treat the ear with fre- 

 quent warm water fomentations and the injection of soapy water or 

 oil and water. 



SCURFY EARS. 



Cattle are subject to scurfy ears, which may be due to a general 

 morbid condition of the skin, or may be confined to the ears alone. 

 The affected animal shows an inclination to rub the ear; thick scales 

 of scurf collect on it, which sometimes have the appearance of hard, 

 dry, horny scales. This condition is chiefly due to a faulty secretion 

 of the sebaceous glands of the ear. Thoroughly clean the ear with a 

 stiff brush, then anoint it, so far as affected, with vaseline 4 parts to 

 1 part of white precipitate ointment. If the scurfy ears are only a 

 part of a general scurfiness of the skin, the condition of the animal 

 needs attention. (See "Pityriasis," p. 329.) 



FROSTBITE. 



It is not uncommon among young cattle which are poorly nourished 

 and exposed outdoors to storms and extreme cold to suffer frostbite 

 of the ear, which may constitute actual freezing of the part. 



Symptoms. — Frostbite presents naturally every degree of severity 

 -from the mere chilling of the tip of the ear to positive freezing and 

 death of a portion. In a day or two after the freezing has occurred the 

 ear will become swollen and very painful; the dead part will remain 

 cold and begin to shrivel; a line of separation then forms between the 

 inflamed and the dead or dying portion, and finally the piece destroyed
