Or when the champing has commenced

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 diarrhœa, 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.
