We think that such ready deception was possible only in earlier times, when education was not widely diffused and when belief in superstitions was fostered. Any such idea completely ignores the modern status of the quack and the success that he meets among even the more intelligent members of the community. Indeed, with the diffusion of information in modern times the quack has secured a wider audience. Superficial ideas of science are disseminated by the newspapers and by the magazines, people think that they understand all about it, and then these ideas are turned to their own advantage by the irregular practitioners of medicine. We have quacks by the score in all the centers of population, making a livelihood by exploiting the ailing, and serving to no small extent to create a feeling of popular discontent towards the physician, because that serves the purpose of quackery. Indeed, it is during the past century or a little more that some of the most striking examples of quackery have occurred. Cagliostro.--Cagliostro, whose story is told in Dumas' "Memoirs of a Physician," and an excellent account of whose life may be found in Carlyle's "Miscellanies," is one of the great quacks and humbugs of history. He began his supposed medical work at Strasburg by the modest claim that during his travels in the East he had found a series of remedies which made old people young. In proof of his power to do this he exhibited his wife. She was a handsome young woman of very shady reputation whom he had married on his travels. She professed to be sixty years of age, though she was really under thirty and looked it, but she claimed that she had a son who had served for many years in the Dutch army. This imposition was so effective that in Strasburg, and subsequently in Paris, the charming pair collected large sums from wealthy old persons, especially from women on whom the marks of time had begun to show, and who expected, as the result of the treatment, to be shortly as young and as handsome-looking as Madame Cagliostro herself.
