preparation of iodine is often made to the digestive.
In directing the constitutional treatment, our chief aim must be to
support the animal system with plenty of gruel until rumination is
restored.

"I need not note that the operation should be performed after the animal
has fasted some hours.

"As the success of the operation depends on an entire removal of the
diseased parts, and as the submaxillary and parotid glands, with
important branches of nerves and blood-vessels, are often enveloped
therein, we must not hesitate to remove the former, nor to divide the
latter. It has occasionally happened that a rupture has been made in the
oesophagus, or pharynx, during the operation. In that case, a portion
of the gruel with which the animal is drenched escapes for a few days;
but I always found that the wound healed by granulation, without any
particular attention.

"The weight of these tumors varies from a few ounces to some pounds. One
that I removed from a two-year-old Galloway bullock, weighed six pounds
and a quarter. A considerable portion of the skin that covered it was
excised and included in the above weight. It comprehended one of the
parotid glands, and I had to divide the trunk of the carotid artery and
jugular vein.

"This affection may be distinguished from parotiditis and other
_phlegmasiae_ by the action of constitutional disturbance, and heat, and
tenderness, and by the lingering progress it makes. I was once called to
a bull laboring under alarming dyspnoea that had gradually increased.
No external enlargement was perceptible; but on introducing my hand into
the mouth, a large polypus was found hanging from the _velum palati_
into the pharynx, greatly obstructing the elevation of the epiglottis
and the passage of food. After performing tracheotomy, to prevent
suffocation, I passed a ligature around its pedicle in the way suggested
by the old anatomist, Cheselden.

"A section of one of these tumors mostly displays several abscesses,
with matter varying in consistency and often very fetid, enclosed in
what seems to me to be fibro-cartilaginous cysts, the exterior of which
sometimes gradually disappears in the surrounding more vascular abnormal
growth. Osseous matter (I judge from the grating of the scalpel upon it)
occasionally enters into the composition of the cysts.

"I have treated this affection in cattle of the Long-horned,
Short-horned, Galloway, and Highland breeds; and from the number of
bul
