In the reign of Edward VI. one Gregg, a poulterer, in Surrey, was set in the pillory at Croydon, and again in the Borough of Southwark, during the time of the fair, for cheating people out of their money, for pretending to cure them with charms, by only looking at the patient, and examining his water. In the reign of James I., an order of council, founded on the statute of Henry, granted to the College of Physicians, was issued to the magistrates of the city of London, for the apprehension of all reputed empirics, to bring them before the censors of the College, in order to their being examined as to their qualifications to be trusted either with the lives or limbs of the subject. On that occasion several mountebanks, (among others, Lamb, Read, and Woodhouse,) water casters, ague charmers, and nostrum venders, were fined, imprisoned, and banished. This wholesome severity, it may be supposed, checked the evil for a time; but in the reign of William III. it became again necessary to put the laws in force against those vermin; in consequence of which many of them were examined, and confessed their utter ignorance even of reading and writing. Some of the miscreants were set in the pillory, and some were put on horse-back with their faces towards the horses’ tails, whipped, branded, and banished. In Stowe’s Annals is to be found an account of a water caster being set on horse-back, his face towards the horse’s tail, which he held in his hand, with his neck decked with a collar of urinals, and being led by the hangman through the city, was whipped, branded, and afterwards banished. One Fairfax, in king William’s time was fined and imprisoned for doing great damage to several people, by his aqua celestis. Antony, for his aurum potabile; Arthur Dee, for advertising remedies which he gave out would cure all diseases; Foster, for selling a powder for the green-sickness; Tenant, a water doctor, who sold his pills for 6l. each; Ayres, for selling purging sugar plumbs; Hunt, for putting up bills in the streets[T] for the cure of diseases; and many others, were all punished, and compelled to relinquish their malpractices. But it is not only the interloping quack—the irregular and illegitimate charlatan and self-dubbed doctor that does mischief and destroys the health of the public, but the “regular” and legitimate pretender to medical knowledge, or as they have been significantly and appropriately termed by Dr. Morrison, the “roturiers,” or dabblers in physic, often do not much less mischief. The following extract from the Manual for Invalids is so much to the purpose, that the wider its circulation can be promoted, the greater good will be produced to society at large.
