disease will pass into the
advanced stages, or, if the animal has been neglected in the early
stages, the treatment must be supplanted with the hypodermic injection
of ergotin, in 5-grain doses, dissolved in 1 dram of water, every six
hours. The limbs may be poulticed above the fetlocks with mustard. Warm
blanketing, to promote perspiration, is to be observed always when there
is no excessive perspiration.

If the disease becomes chronic (encephalitis or meningitis), we must
place our reliance upon alteratives and tonics, with such incidental
treatment as special symptoms may demand. Iodid of potassium in 2-dram
doses should be given three times a day and 1 dram of calomel once a day
to induce absorption of effusions or thickened membranes. Tonics, in the
form of iodid of iron in 1-dram doses, to which is added 2 drams of
powdered hydrastis, may also be given every six or eight hours, as soon
as the active fever has abated. After the disappearance of the acute
symptoms, blisters (cantharides ointment) may be applied behind the
poll. When paralytic effects remain after the disappearance of all other
symptoms, sulphate of strychnia in 2-grain doses, in combination with
the other tonics, may be given twice a day and be continued until it
produces muscular twitching. In some cases of paralysis, as of the lips
or throat, benefit may be derived from the moderate use of the electric
battery. Many of the recoveries will, however, under the most active and
early treatment, be but partial, and in all cases the animals become
predisposed to subsequent attacks. A long time should be allowed to pass
before the animal is exposed to severe work or great heat. When the
disease depends upon mechanical injuries, they have to be treated and
all causes of irritation to the brain removed. If it is due to stable
miasma, uremic poisoning, pyemia, influenza, rheumatism, toxic agents,
etc., they should receive prompt attention for their removal or
mitigation.

Cerebral softening, abscess, and sclerosis are practically inaccessible
to treatment, otherwise than such relief as may be afforded by the
administration of opiates and general tonics, and, in fact, the
diagnosis is largely presumptive.

CONGESTION OF THE BRAIN, OR MEGRIMS.

Congestion of the brain consists in an accumulation of blood in the
vessels, also called hyperemia, or engorgement. It may be active or
passive--active when there is an undue accumulation of blood or
