structures are apt to be affected, and should the animal survive, serious
sloughing may follow, if the blister be repeated too quickly on one part.

The directions given above apply to that stage when the eye and other
symptoms indicate the approach of fits, or when the champing has
commenced. The tonic pills and liquor arsenicalis may also then be
continued; but when the fits have positively occurred, other measures must
be adopted. If colic should attack the animal, laudanum must be
administered, and in small but repeated doses, until the pain is
dismissed. Opium is of itself objectionable; but the drug does less injury
than does the suffering, and, therefore, we choose between the two evils.
From five to twenty drops of the tincture, combined with half-a-drachm to
two drachms of sulphuric ether, may be given every half-hour during the
paroxysm; and either the dose diminished or the intervals increased as the
agony lessens, the animal being at the same time constantly watched. The
ethereal enemas should be simultaneously exhibited, and repeated every
half-hour. When a fit occurs, nothing should during its existence be given
by the mouth, except with the stomach-pump, or by means of a large-sized
catheter introduced into the pharynx. Unless this precaution be taken,
there is much danger of the fluid being carried into the lungs. Ether by
injection, however, is of every service, and where the proper instruments
are at hand, it ought also to be given by the mouth. The doses have been
described. To the liquor arsenicalis, from half a drop to two drops of the
tincture of aconite may with every dose be blended; and the solution of
the chloride of lime should be mingled with the injections, as ordered for
diarrhoea, which, if not present, is certain to be near at hand. The
following may also be exhibited, either as a soft mass or as a fluid
mixture:--

Chlorate of potash One to four grains.
Aromatic powder Half-a-drachm to two drachms.

Or,

Carbonate of ammonia Five grains to a scruple.
Chalk One to four scruples.
Aromatic confection One to four scruples.

Either of the above may be tried every third hour, but on no account ought
the warm bath to be used. An embrocation, as directed for rheumatism, may
be employed to the feet and legs, and warm turpentine may, as described in
diarrhoea, be used to the abdomen. Cold or evaporating lotions to the head
are of ser
