Boing Boing linked to some articles about the original book of magic tricks,
Hocus Pocus Junior, (1634).
Hocus Pocus Junior was actually a remix of parts of Reginald Scot's
The Discoverie of Witchcraft (1584), published 50 years earlier to debunk all sorts of magic.
The Discouerie of Witchcraft is available in a beautifully scanned copy of an 1886 reprint.
