he brain or nervous system, while in other
instances disease of the brain has been found in the form of thickening
of the membranes, abscesses, and tumors, and in some cases the affection
has been manifested in connection with a diseased condition of the blood.
The cause has also been traced to reflex irritation, due to teething,
worms, and chronic indigestion.

_Treatment._--When the affection is due to the last-named causes treatment
may be successful if the cause is removed. If there are symptoms of worms
or of indigestion, follow the general treatment advised for those troubles
under their proper heads. If due to irritation caused by teething, the
inflamed gums must be lanced. Examination of the mouth often develops the
fact that one of the temporary teeth causes much irritation by remaining
unshed, and thereby interfering with the growth of a permanent tooth. The
offending tooth should be extracted. When the cause of epilepsy can not be
discovered, it must be confessed that there is no prospect of a cure.
However, some benefit may be expected from the occasional administration of
a purgative dose of medicine. A pound of Epsom salt dissolved in a quart of
warm water, for a cow of average size, may be given as a drench once or
twice a month. In addition to the purgative, 4 drams of bromid of
potassium, dissolved in the drinking water, three times a day, has proved
very beneficial in some cases.

SUNSTROKE (PROSTRATION FROM HEAT).

Owing to the fact that cattle are seldom put to work at which they would
have to undergo severe exertion, especially in collars, they are not
frequently prostrated by the extreme heat of the summer months. When at
pasture they select the coolest places in the shade of trees, in water,
etc., when the heat becomes oppressive, and thereby avoid, as much as
possible, the effects of it.

It does happen, however, that cattle that have been kept up for the purpose
of fattening, when driven some distance in very hot weather, are sometimes
prostrated, but it must be remembered that it is not really necessary for
the animal to be exposed to the rays of the sun, as those confined in hot,
close places may suffer. This often happens in shipping, when they are
crowded together in cars.

_Symptoms._--The premonitory signs are those of exhaustion--dullness,
panting, frothing at the mouth, tongue hanging out, irregular gait,
uneasiness, palpitation--when, if the circumstances which tend to the
prostr
