both sides, the respirations are quickened and labored, the pulse small and
quick, the eyes are prominent and the mucous membrane congested. Death
results from asphyxia brought on by the distended paunch pushing forward
and interfering with the movement of the lungs and the absorption of the
poisonous gases.

_The treatment_ is both preventive and medicinal. This form of acute
indigestion can be largely prevented by practising the following preventive
measures: All changes in the feed should be made gradually, especially if
the ration fed is heavy, or the new ration consists largely of green,
succulent feed. Cattle pasturing on clover should be kept under close
observation. It is not advisable to pasture cattle on rank growths of
clover that are wet with dew or a light rain. Bloating can be quickly
relieved by puncturing the wall of the paunch with the trocar and cannula.
The operation is quite simple and is not followed by bad results. The
instrument is plunged through the walls of the abdomen and rumen in the
most prominent portion of the flank, midway between the border of the last
rib and the point of the haunch (Fig. 13). The trocar is then withdrawn
from the cannula. After the gas has escaped through the cannula, the trocar
is replaced and the instrument withdrawn. After using the trocar and
cannula, the instrument should be cleaned by placing it in boiling hot
water. It is advisable to wash the skin at the seat of the operation with a
disinfectant before operating. In chronic tympanitis, it is sometimes
advisable to leave the cannula in position by tying a tape to the flange,
passing it around the body and tying.

As a cathartic for cattle, we may give one quart of linseed and from two to
four ounces of turpentine, or one to two pounds of Epsom or Glauber's
salts, dissolved in plenty of water. Sheep may be given about one-fourth
the dose recommended for cattle.
