bleed the animal.

If the animal retains an appetite, a soft diet is preferable, such as
scalded oats, bran mashes, and grass, if in season. If he refuses cooked
feed, allow in small quantities anything he will eat. Hay, cob corn,
oats, bread, apples, and carrots may be tried in turn. Some horses will
drink sweet milk when they refuse all other kinds of feed, and
especially is this the case if the drinking water is withheld for a
while. One or 2 gallons at a time, four or five times a day, will
support life. Bear in mind that when the disease is established recovery
can not occur in less than two or three weeks, and more time may be
necessary. Good nursing and patience are required.

When the symptoms have abated and nothing remains of the disease except
the cough and a white discharge from the nostrils, all other medicines
should be discontinued and a course of tonic treatment pursued. Give the
following mixture: Reduced iron, 3 ounces; powdered gentian, 8 ounces;
mix well together and divide into sixteen powders. Give a powder every
night and morning mixed with bran and oats, if the animal will eat it,
or shaken with about a pint of flaxseed tea and administered as a
drench.

If the cough remains after the horse is apparently well, give 1 dram of
iodid of potassium dissolved in a bucketful of drinking water one hour
before each meal for two or three weeks if necessary. Do not put the
animal to work too soon after recovery. Allow ample time to regain
strength. This disease is prone to become chronic and may run into an
incurable case of thick wind.

PLEURISY.

The thoracic cavity is divided into two lateral compartments, each
containing one lung and a part of the heart. Each lung has its separate
pleural membrane, or covering. The pleura is the thin, glistening
membrane that covers the lung and also completely covers the internal
walls of the chest. It is very thin, and to the ordinary observer
appears to be part of the lung, which, in fact, it is for all practical
purposes. The smooth, shiny surface of the lung, as well as the smooth,
shiny surface so familiar on the rib, is the pleura. In health this
surface is always moist. A fluid is thrown off by the pleura, which
causes the surface to be constantly moist. This is to prevent the
effects of friction between the lungs and the walls of the chest and
other contiguous parts which come in contact. It must be remembered that
the lungs are dilating each time a br
