Of the various remedial plans I have pursued, none have appeared more uniformly beneficial than a course of emetics, steadily persisted in twice a week. In the intermediate days _alteratives_ were administered, with the occasional use of a purgative, provided the dog was strong, fat, and plethoric; otherwise this was dispensed with: but it should be remembered, that this remedial plan must be uniformly and long continued, to ensure permanent benefit. The alterative is as follows:— Calomel (_submuriate of mercury_) ½ gr. Nitre (_nitrate of potash_) 5 gr. Cream of tartar (_supertartrate of potash_) 10 gr. Antimonial powder 2 gr.—Mix. This may be given either as a powder, or it may be made into a ball with honey; this dose being repeated once or twice a day, according to the urgency of the case: the quantities may be also lessened or increased according to the effect produced; the recipe is intended for a dog of middling size. On the morning that the emetic is given, the alterative should be omitted; and where the alterative is repeated night and morning, it will be prudent to watch the mouth, that salivation may not unexpectedly come on. If this should happen, discontinue the medicine for some days. Where also the calomel has been found to disagree, I have substituted the following alterative with benefit:— Nitre (_nitrate of potash_) 2 gr. Tartar emetic (_tartarised antimony_) ¼ gr. Powdered Foxglove (_digitalis_) ½ gr.—Mix. This may be given as the other, and alternated with the emetic also, watching the effect of the foxglove, through the medium of the pulse, that they may not be too violent. In some cases of long standing, where the attendant cough has been very harsh, noisy, and distressing, I have added ten, twenty, or thirty drops of tincture of opium (_laudanum_), or the eighth, sixth, or fourth part of a grain of opium, to each alterative with advantage. In other instances, the cough has been best allayed by an evening opiate of double the strength before prescribed. I have, now and then, experienced benefit also from the use of the balsamic gums, which may be all tried, therefore, in obstinate cases. Relief has been obtained likewise from the following, given every morning:— Powdered squill ½ gr. Gum ammoniacum, powdered 5 gr. Balsam Peru 3 gr. Benzoic acid 1 gr. Anisated balsam of sulphur to form a ball. Or, Inspissated juice of the white garden lettuce ½ dr. Tincture of balsam of Tolu 1 dr. Powdered gum arabic and extract of liquorice 1 oz. each Make into balls, and give one night and morning. * * * * *
