ses should be fastened to the horns in such manner as to
reach below the eyes. This should be kept wet with cold water during the
day and removed at night. If there is much fever and constitutional
disturbance, it becomes advisable to administer 1 pound of Epsom salt
dissolved in 1 quart of water.

INFECTIOUS CATARRHAL CONJUNCTIVITIS (SPECIFIC
OPHTHALMIA).

This generally appears in an enzootic or epizootic form and affects a
considerable number in the herd. It is distinctly a contagious disease and
may be brought into a previously healthy herd by one infected animal. It
may continue in a herd for a season or for several years, affecting all
newly purchased animals. It is seldom seen in the winter months. It affects
old and young animals alike.

_Symptoms._--This form of catarrh conjunctivitis is characterized chiefly
by a mucopurulent discharge from the eyes, an intense degree of
inflammation of the mucous membrane, accompanied with swelling of the
eyelids and an early opacity of the cornea. The flow of tears is mixed with
pus, sometimes streaked with blood, and the skin of the face is kept moist
and soiled. The eyes are kept continually closed. The implication of the
cornea in the disease frequently blinds the animal for a time, and
occasionally suppurative keratitis, ulcers of the cornea, or staphyloma
supervene. The attack is marked from the onset by fever, partial loss of
appetite, partial loss of milk, suspended rumination, and separation from
the herd.

_Treatment._--The animal should be housed in a cool, dark stable, supplied
with plenty of fresh water to drink and soft, succulent feed. Administer 1
pound of Epsom salt--if a very large animal, use 1-1/2 pounds--dissolved in
2 or 3 pints of water. For an eyewash, take boracic acid, 1 dram, and pour
4 ounces of boiling water over it. Use this as often as is convenient,
applying it directly to the eye. In the majority of cases improvement
becomes manifest in a few days, and the eye becomes clear and free from
inflammation in 10 days or 2 weeks. Where the disease develops ulceration
of the cornea, or well-marked, deep-seated keratitis, the treatment
recommended for those conditions should be adopted.

_Prevention._--Whenever this affection appears in a herd all the unaffected
animals should be moved to fields which possess a different character of
soil and feed. The water should also be changed, especially if they have
been obtaining it from a stagnant pond.
