Transcriber's Note:

• Hyphens splitting words across lines have been removed.
• Original spellings have generally been retained, but the Errata from the Second Edition (at the end), and a mistake in the Errata (!) have been marked like this.
• The Latin epigraph translates as: “They all represent themselves as Doctors—The Uneducated, The Priest, The Nurse, and The Barber, The Apothecary, The Old Woman.”
