The belief in an universal remedy has long been abandoned, even among the vulgar, and long exploded in those classes of society, which are not influenced by prejudice, or tinctured with fanaticism. It is, however, sincerely to be regretted, that the daily press continues to be inundated with advertisements; and that the lower, and less informed class of the community, are still imposed upon by a set of privileged impostors, who frequently puzzle the intelligent to decide, whether the impudence or the industry with which they endeavour to establish the reputation of their respective poisons, be the most prominent feature in their character. In illustration of this last observation, it may further be observed, that most of the nostrums advertised as cough drops, etc., are preparations of opium, similar, but inferior, to the well-known paregoric elixir of the shops, but disguised and rendered more deleterious by the addition of heating and aromatic gums. The injury which may be occasioned by the indiscriminate employment of such medicines might be very serious and irremediable, as is well known to every person possessing the smallest portion of medical knowledge. The boasted, though groundless pretensions of certain illiterate empirics to cure diseases which have eluded the skill and penetration of the faculty, is another absurdity into which people of good common sense have been most woefully entrapped. The lessons of experience ought to prove the most useful, as purchased at the greatest trouble and expense; but if people choose to run over a precipice with their eyes open, they leave themselves nothing to regret, and the public less to lament, by their fall. It was justly observed by the sagacious and intelligent Bacon, "that a reflecting physician is not directed by the opinion which the multitude entertain of a favourite remedy, but that be must be guided by a sound judgment; and consequently, he is led to make very important distinctions between those things which only by their name pass for medical remedies, and others, which in reality possess healing powers." We avail ourselves of the quotation, as it indirectly censures the conduct of certain medical practitioners, who do not scruple to recommend what are vulgarly called patent and other quack preparations, the composition of which is carefully concealed from the public. Having acquired their unmerited reputation by mere chance, and being supported by the most refined artifices, in order to delude the unwary, we are unable to come at the evidence of perhaps nine tenths of those who have experienced their fatal effects, and who are now no longer in a situation to complain.
