dissolving the
above-named quantity in a half pint of water and given as a drench.

As a digestive tonic the following is good: Glauber's salt, 2 pounds;
common salt, 1 pound; baking soda, one-half pound. Of this a heaping
tablespoonful may be given in each feed. If diarrhea exists, the
treatment advised below may be used.

DIARRHEA.

Diarrhea is due to indigestion or intestinal catarrh or to irritation of
the bowels from eating moldy or musty feed, drinking stagnant water,
diseased condition of the teeth, eating irritating substances, to being
kept on low, marshy pastures, and to exposure during cold nights, or in
low, damp stables. Some horses are predisposed to scour and are called
"washy" by horsemen; they are those with long bodies, long legs, and
narrow, flat sides. Horses of this build are almost sure to scour if fed
or watered immediately before being put to work. Fast or road work, of
course, aggravates this trouble. Diarrhea may exist as a complication of
other diseases, as pneumonia and influenza, for instance, and again
during the diseases of the liver.

The symptoms are the frequent evacuations of liquid stools, with or
without pronounced abdominal pain, loss of appetite, emaciation, etc.

_Treatment_ is at times very simple, but requires the utmost care and
judgment. If due to faulty feed or water it is sufficient to change
these. If it results from some irritant in the intestines this is best
gotten rid of by the administration of an oleaginous purge, for which
nothing is better than castor oil, although raw linseed oil may be used
if the case is not severe. The diarrhea often disappears with the
cessation of the operation of the medicine. If, however, purging
continues it may be checked by giving wheat flour in water, starch
water, white-oak bark tea, chalk, opium, or half-dram doses of sulphuric
acid in one-half pint of water twice or thrice daily. Good results
follow the use of powdered opium 2 drams and subnitrate of bismuth 1
ounce, repeated three times a day. In all cases it should be remembered
to look to the water and feed the horse is receiving. If either of these
is at fault it is at once to be discontinued. We should feed sparingly
of good, easily digested feeds. With that peculiar build of nervous
horses that scour on the road but little can be done as a rule. They
should be watered and fed as long as possible before going on a drive.
If there is much flatulency accompanying diarrhea ba
