356 DISEASES OF CATTLE. 



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

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

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

 the latter. 



FOREIGN BODIES IN THE EAR. 



Bugs have been knoAvn to gain entrance into the ears of animals. 

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

 ing in the woods; also pieces of wood from a stanchion maj^ be 

 lodged accidentally in the ear. 



Symptoms. — There is usually a continuous uneasiness or fre(iuent 

 shaking of the head, occasionally the manifestation of exceedingly 

 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 reveals the 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 is hidden from sight; 

 then a probe may be inserted to feel for the object, which, when 

 found, should be removed, even if it becomes necessary to split the 

 ear at the base. Afterwards treat the ear with frequent warm water 

 fomentations and the injection of soapy water or oil and water. 



SCURFY EARS. 



Cattle are subject to scurfy ears, which may be owing to a generally 

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

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

 which sometimes have the appearance of hard, dry. homy scales, 

 of scurf collect on it. This condition is chiefly caused by 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 nour- 

 ished 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 becomes swollen and very painful ; the dead part remains 

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