The most recent case of medical imposition practised upon the public, that has come to our knowledge, is that of a practitioner in New York city, who, by receiving a letter from sick or diseased persons, giving the year, day, and hour of their birth, immediately forwards them a package of medicine suited to their case. It seems to be a matter of astonishment to many how he arrives at a knowledge of their state of health, so as to be able to adapt his remedies to their several conditions. But it is probably done on the principles of astrology--by finding the planet under which the patient is born, the diseases appertaining to that planet, and the _plants_ belonging to the same, which are supposed to have a special effect upon the relative _planetary_ diseases. Culpepper, in his English Herbal, if we mistake not, arranges or classifies all plants and diseases in this way, and contends that astrology is the only true key to medical science. Fortune telling is practised upon a similar plan, through the agency of _astrology_. But the whole is a deception, entirely unworthy the age in which we live. The fortune teller may hit upon an incident which is correct, once in a while, and it would be strange if he did not. And the _astrological physician_ may prescribe some little tonic, or stimulant, that will raise the drooping spirits for a time, and actually lead the hopeful patient to believe that he or she is fast recovering from their long-afflictive maladies. But the sequel too often teaches them the lesson of their sad mistake. The history of Valentine Greataks, the son of an Irish gentleman, who lived in the time of Cromwell, is very similar to what we have related of the prophet of Colchester. And about the same time, Francisco Bagnone, a Capuchin friar, was famous in Italy, having a gift of healing, principally by his hands only. Multitudes of sick people attended him wherever he went, to obtain healing mercy. And here, perhaps, we may find the true principle on which all the impositions of Popery have been maintained for centuries gone by. It cannot be a matter of surprise that, if men, of more information than they, can be made to believe that they are delivered from disease by experiments of magnetism, tractors, or the mere touch of the hand, these should believe that they are healed by visiting the tombs of saints; by standing before their statues; being touched by nails from their coffins, rings from their fingers, or by the bones of the fingers themselves.
