The necessity of resorting to the assistance of either one or the other of these worthies is equally unfortunate, as the former will most generally kill the patient by slow degrees in forcibly and largely administering the two modern specifics for all canine affections, viz.: "soap pills and flowers of sulphur." While the latter, more bold but not less ignorant than the former, and his practice is perhaps the preferable of the two evils, will murder the dog out-right by the free exhibition of calomel, nux vomica and other deleterious substances, of the operation of which he has but little knowledge or conception. This latter system, as before said, is the most preferable, as its adoption secures for our favourite a speedy termination of his sufferings, and also relieves our own minds from a state of suspense that illustrates too forcibly the remark, "Hope deferred maketh the heart sick." REMEDIAL MEANS FOR THE CURE OF DISEASES. There are but few remedies useful for the cure of diseases in the human race that might not he employed by a skilful practitioner in overcoming the same or different ailments in the dog. There are, however, several drugs that cannot be used in the same proportions for the one as for the other, without danger of producing fatal consequences, as instanced in calomel, a medicine so often abused by those who pretend to a knowledge of its administration in the maladies of dogs. This article, though given with impunity to mankind in doses varying from five grains to twenty grains, as also oftentimes administered to horses in quantities three or four times as great, without any appreciable effect, will not unfrequently, in minute doses of three grains to four grains, produce the most violent symptoms in the strongest dogs. We have seen severe vomiting and purging occasioned by these small doses, and we once salivated a large mastiff by the administration of two blue pills. It is thus that both the regular physician, and even the veterinary surgeon, unacquainted with this remarkable peculiarity, will make fatal mistakes; and how much oftener must such blunders take place when we intrust our canine friends to the care of stable-boys, or a "routine horse-doctor!" Nux vomica, another medicine much used, and most important in the treatment of all nervous affections, is particularly noxious to dogs even in small quantities; a dose sufficient for a human subject under some circumstances, would almost inevitably destroy the animal under the same or analogous conditions. A drachm of the powdered nux vomica is sufficient to destroy the largest and most powerful dog, while a few grains will sometimes produce death in a few minutes if administered to smaller animals.
