m iodid of lead in the
system, which is rapidly excreted by the kidneys. If much muscular
weakness or paralysis is present, sulphate of iron in 1-dram doses and
strychnia in 2-grain doses may be given twice a day. In all cases of
suspected lead poisoning all utensils which have entered into the supply
of feed or water should be examined for the presence of soluble lead. If
it occurs near lead works, great care must be given to the supply of
uncontaminated fodder, etc.

UREMIA.

Uremic poisoning may affect the brain in nephritis, acute albuminuria,
or when, from any cause, the functions of the kidneys become impaired or
suppressed and urea (a natural product) is no longer eliminated from
these organs, causing it to accumulate in the system and give rise to
uremic poisoning.

Uremic poisoning is usually preceded by dropsy of the limbs or abdomen;
a peculiar, fetid breath is often noticed; then drowsiness, attacks of
diarrhea, and general debility ensue. Suddenly extreme stupor or coma
develops; the surface of the body becomes cold; the pupils are
insensible to light; the pulse slow and intermitting; the breathing
labored, and death supervenes. The temperature throughout the disease is
seldom increased, unless the disease becomes complicated with acute,
inflammatory disease of the brain or respiratory organs, which often
occur as a result of the urea in the circulation. Albumen and tube casts
may frequently be found in the urine. The disease almost invariably
proves fatal.

Treatment must be directed to a removal of the cause.

ELECTRIC SHOCK.

Electric shock, from coming in contact with electric wires, is becoming
a matter of rather frequent occurrence, and has a similar effect upon
the animal system as a shock from lightning. Two degrees of electric or
lightning shock may be observed, one producing temporary contraction of
muscles and insensibility, from which recovery is possible, the other
killing directly, by producing a condition of nervous and general
insensibility. In shocks which are not immediately fatal the animal is
usually insensible, the respiration slow, labored, or gasping, the pulse
slow, feeble, and irregular, and the pupils dilated and not sensitive,
or they may be contracted and sensitive. The temperature is lowered.
There may be a tendency to convulsions or spasms. The predominating
symptoms are extreme cardiac and respiratory depression.

_Treatment._--Sulphate of atropia should be given
