The Pennsylvania Gazette
Run away on the 30th of December last, from the subscriber living in Packston township, Lancaster county, and province of Pennsylvania, a servant man, named Richard Pritchard, born in Wales, but was brought up in Ireland, a middle size fellow, well set, of a fresh complexion, one of his under teeth longer than the rest,  with short black hair, almost as coarse as horsehair, speaks with a lisp, and takes snuff, about 25 or 30 years of age : Had on when he went away, a large felt hat, worsted cap, two shorts, one ruffled, a blue German serge coat, with flash sleeves, an olive green coat, half worn, long waisted, with short skirts, old cloth breeches, with metal buttons, dark brown stockings, and a pair of blue worsted ones, and old shoes, one of them has a slit in the upper leather, it being too tight, with brass buckles: Said servant has been in the army, and on board a man of war, and pretends to know something of the plaisterer, painter, and miller business.
Whoever takes up and secures said servant, or gives notice of him, to Jeremiah Warder, Hatter,  in Philadelphia, so that his master may have him again, shall have Three Pounds reward, and reasonable charges, paid by James McKnight, or John Harris, Ferryman.
1. Part of the reason for checking the teeth of a servant was to determine his ability to subsist on a rough diet, however, the aspect of police work involving the checking of dental records seems as if it might owe something to the slave-catching business of old.
2. The age of people sold into bondage was largely a matter of speculation as many were orphaned or sold out of poor families with no records of attending doctors or midwives, such that existed for the wealthy.
3. Hatters worked with mercury, which was used in processing animal products in the making of hats. Mercury poisoning results in insanity, hence the old term, "mad as a hatter." Ironically, mercury was also used to treat syphilis.
