y large gangrenous
sloughs may form. The temperature is never very high, the pulse is
frequent and compressible, and becomes feebler as the animal loses
strength. A cough is usually present. The urine is scanty and high
colored, and when the intestines are much affected a bloody diarrhea may
set in, with colicky pains. Some of the internal organs become
implicated in the disease, the lungs may become edematous, extravasation
may occur in the intestinal canal, or effusion of serum into the cavity
of the chest or abdomen; occasionally the brain becomes affected. A few
cases run a mild course and recovery may commence in three or four days;
generally, however, the outlook is unfavorable. In severe cases septic
poisoning is liable to occur, which soon brings the case to a fatal
issue.

_Pathology._--On section we find the capillaries dilated, the connective
tissue filled with a coagulable or coagulated lymph, and frequently we
may discover gangrenous spots beneath the skin or involving the skin.
The lymphatic glands are swollen and inflamed. Extensive extravasations
of blood may be found embedded between the coats of the intestines, or
excessive effusion into the substance of the lungs.

_Treatment._--Diffusible stimulants and tonics should be given from the
start. Carbonate of ammonia, 1 dram, fluid extract of red cinchona bark,
2 drams, and tincture of ginger half an ounce, with half a pint of
water; thin gruel or milk should be given every four or six hours. But
especial care should be exercised to avoid injury by drenching. If the
horse has difficulty in getting the head up and swallowing, smaller
doses must be given with a small hard-rubber syringe. Sulphate of iron
in 1-dram doses may be dissolved in water and given every six hours.
Chlorate of potassium, in 2-ounce doses, may be given every eight or
twelve hours. Colloidal silver may be administered intravenously in
doses of from 5 to 12 grains. Washings with lead and alum water are
useful and may be repeated several times each day. If the swellings are
very great, they may be incised freely and the resulting wounds should
be washed at least twice daily with a warm 3 per cent solution of
carbolic acid or other good antiseptic. Tracheotomy may be necessary.
Complications, when they arise, must be treated with proper
circumspection.

The lymphatic, or absorbent, system is connected with the blood-vascular
system, and consists o
