stone, 1/2 oz. Mix and apply three times a day. If the horse is over
four years old, or in any case where there is not sufficient, in
addition to it, you will fit a bar of lead just above it, wiring the
ends together, so it constantly wears upon the enlargement, and the
two together, will cure nine cases out of every ten in six weeks.


333. POLL EVIL AND FISTULA

Take 1 lb. common potash dissolved in 1/2 pint of water. Add 1/2 oz.
extract of belladona and 1 oz. gum-arabic dissolved in a little
water; work all into a paste with wheat flour, and box or bottle up
tight. In applying this, the place should be well cleansed with
soap-suds, (castile soap is best) then tallow should be applied all
around by the paste dissolving and running over it. Now this paste
must be pressed to the bottom of all the orifices; if very deep
it must be made sufficiently thin to inject by means of a small
syringe, and repeated once in two days, until the callous pipes, and
hard fibrous base around the poll evil, or fistula, is completely
destroyed. Sometimes one application has cured cases of this kind,
but it will generally require two or three. If the horse cannot be
kept up, you will put a piece of oiled cloth over the place. The
advantage of this caustic over all others is that less pain and
inflammation is induced. The sores may be cured by the following
or Sloan's ointment: ceder oil is to be applied to the tendons,
to prevent them stiffening, in pole evil, or other cases.
