ng placed in front of the
windpipe below the angle of the jaw. This swelling may be hard, soft, or
doughy in consistence, and with each beat of the heart it may pulsate like
an artery. It may cause labored breathing by pressure on the windpipe, and
death may result from pressure on this structure, on the gullet, or on the
adjoining large vessels.

_Treatment._--In young animals the treatment is usually satisfactory, and
consists in giving the animal a complete change of feed and plenty of
exercise in the open air. If the condition appears enzootic in the
district, remove the animal to another location when possible. Iodin,
either in the form of ointment or the tincture, should be applied to the
swelling. Injections of iodin solution, 5 grains of iodin in 1 dram of 25
per cent alcohol, may also be made into the substance of the gland. When
the swelling which follows this injection has subsided it may be repeated.
Potassium iodid should be given internally in 1-1/2 dram doses twice daily
for a cow, or in 20-grain doses twice a day for a calf. Extirpation of all
but a small section of the swelling may be successfully accomplished by a
qualified veterinarian, but if it should be entirely removed, myxedema and
death follow.

FIBROMA.

Fibromas are tumors made up chiefly of connective tissue and are usually
confined to the skin and subcutaneous tissue. Indurative fibromas of the
skin appear as tumors of gelatinous connective tissue or as firm, white
vascular connective tissue growths, which are more or less sharply
outlined, move readily over the underlying tissues in company with the
skin, and owe their origin to mechanical injuries, perforating wounds,
repeated abrasions, or the invasion of pus cocci or botryomyces into the
tissues.

These tumors in cattle are frequently found upon the dewlap as solid lumps,
hard as stone to the touch, lying loosely between the layers of skin, and
gradually losing themselves in the softer tissues of the neck above, or as
smooth, hard tumors of glistening white substance with interlacing lines of
softer tissue. They may also be found in the region of the knee or at the
elbow. The skin over the growths, in accordance with the originating cause,
will be found chafed, covered with scabs, or even ulcerated and accompanied
with collateral edema.

These connective tissue tumors grow slowly but reach enormous size. They
sometimes follow injuries to the region of the throat and form there as
