1 Of all the subjects that afford opportunities for the satiric pen in the Metropolis, perhaps there is none more abundant or prolific than that of Quackery. Dr. Johnson observes, that “_cheats can seldom stand long against laughter_.” But if a judgment is really to be formed from existing facts, it may be supposed that times are so materially changed since the residence of that able writer in this sublunary sphere, that the reverse of the position may with greater propriety be asserted. For such is the prevailing practice of the present day, that, according to the opinion of thousands, there is nothing to be done without a vast deal more of profession and pretence than actual power, and he who is the best able to bear laughing at, is the most likely to realize the hopes he entertains of obtaining celebrity, and of having his labours crowned with success. Nothing can be more evident than this in the Medical profession, though there are successful Quacks of all kinds, and in all situations, to be found in London. This may truly be called the age of Quackery, from the abundance of impostors of every kind that prey upon society; and such as cannot or will not think for themselves, ought to be guarded in a publication of this nature, against the fraudulent acts of those persons who make it their business and profit to deteriorate the health, morals, and amusements of the public. But, in the present instance, we are speaking of the Medical Quack only, than which perhaps there is none more remarkable.
