diameter. Twist each end of the one rope twice around the other, so that
this ovoid will remain when they are drawn tight. (Pls. XXII and XXIII.)
Tie a strap or rope around the back part of the neck and a surcingle around
the body. Place the rope truss on the animal so that the ovoid ring will
surround the vulva, the two ascending ropes on the right and left of the
tail and the two descending ones down inside the thighs on the right and
left of the udder. These descending ropes are carried forward on the sides
of the body and tied to the surcingle and to the neck collar. The ascending
ropes proceed forward on the middle of the back, twisting over each other,
and are tied to the surcingle and collar. The upper and lower ropes are
drawn so tightly that the rope ring is made to press firmly all around the
vulva without risk of displacement. This should be worn for several days,
until the womb shall have closed and all risk of further eversion is at an
end. Variations of this device are found in the use of a narrow triangle of
iron applied around the vulva and fixed by a similar arrangement of ropes,
surcingle, and collar (Pl. XXIII, fig. 3), a common crupper similarly held
around the vulva (Pl. XXII, fig. 1), stitches through the vulva, and wire
inserted through the skin on the two hips (Pl. XXIII, fig. 2), so that they
will cross behind the vulva; also pessaries of various kinds should be
inserted into the vagina. None of these devices, however, present any
advantage over the simple and comparatively painless rope truss described
above. Such additional precautions as keeping the cow in a stall higher
behind than in front, and seeing that the diet is slightly laxative and
nonstimulating may be named. If straining is persistent, ounce doses of
laudanum may be used twice a day, and the same may be injected into the
vagina.

If the womb has been cut off, injections of a solution of a teaspoonful of
carbolic acid in a quart of water should be used daily, or more frequently,
until the discharge ceases.

EVERSION OF THE BLADDER.

A genuine eversion of the bladder is almost unknown in the cow, owing to
the extreme narrowness of its mouth. The protrusion of the bladder,
however, through a laceration sustained in calving, in the floor of the
vagina and its subsequent protrusion through the vulva, is sometimes met
with. In this case the protruding bladder contains urine; this can never be
the case in a real eversion, in which
