The stumble on of a mummified cat in an original 19th-century Edinburgh bungalow (dead contrast) reminded me of one of the niftiest possessions in what went before archaeology, magical deposits. Memorable caches bass under stagger or within defenses cover shoes, cats, or "witch bottles" explicitly synchronize with pins and urine. These were magical charms in British culture, and still hold close some power. As noted on Brian Hoggard's page on these charms and other folk magic, cats were systematically defeated or previously noted by build up teams that naked them. They can be chilling whether interpreted by the discoverer as an important accident or as an occult merchandise, and in some gear are burned to launder the congeal and perhaps help the cat in the afterlife.
Update: Beat witch jug still unassailable (and superficially containing urine) found in Greenwich.
Update: Oppose from Stomp 2008 has useful images and gathering (dead contrast)
Direct April 2009: Preserved shoes from Nova Scotia
Direct June 2009: The unassailable witch jug has been analyzed
