"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 becomes
swollen and very painful; the dead part remains cold and begins to shrivel;
a line of separation then forms between the inflamed and the dead or dying
portion, and finally the piece destroyed drops off, leaving a raw healing
surface. When the ear is only slightly affected by the cold, an excoriation
or peeling off of superficial skin takes place, accompanied with some pain
and itching.

_Treatment._--A good liniment for frozen ears is a mixture of turpentine,
ammonia, and chloroform, of each 1 part, added to 6 parts of sweet oil. Rub
this on the ear several times a day. It will relieve pain and stimulate the
circulation, thus favoring a recovery of the injured structures.

LACERATIONS OF THE EAR.

Aggressive dogs are the most frequent cause of lacerated ear, generally
leaving a torn, ragged edge and bruised cartilage.

If the wound is extensive, a trimming of the ragged edges becomes
necessary; then the edges should be fastened together with silver wire,
catgut, or strong, thick, linen thread, taking a deep hold, and pine tar
applied.

DISEASE OF THE CARTILAGE AND NECROSIS.

Occasionally the cartilages of the ear become affected, usually the result
of a deep bruise; pus forms, burrows under the skin, and may find a
discharge from any part of the ear more or less distant from the seat of
the disease. When the cartilage has been extensively injured, pieces of it
may become dead (necrosed) and dissolve, to be carried away with the pus,
or it may lead to extensive sloughing and the formation of numerous running
sores. In the disease of the cartilage there is seldom much swelling or
great pain. The discharge is usually very offensive, and occasionally
streaked with blood. Whenever there is a long-continued, persistent
discharge from one or more openings in the ear, disease of the cartilage
may be suspected.

_Treatment._--The sinus formed by the passage of matter should be pr
