CONJURATION, conjuration (Cycl.) fignifies a plot or con- federacy, made by perfons combining together by oath or promife, to tlo fome public harm.
But it was more particularly ufed, formerly, for the having a perfonal conference with the devil, or fome evil Spirit, to know any fecret, or to effect any purpofe. Anno 5 Eliz. c. 16.
It is faid in fome of our law books, that the difference be- tween conjuration and tvitchcraft is, that the former endea- vours by prayers and invocation of God's powerful name, to compel the devil to fay or do what the offender com- mands him ; the latter deals rather by friendly and voluntary conference or agreement with the devil or familiar, to have the offender's defires ferved, in lieu of blood, or other gift offered to the devil, efpecially of the offender's foul. And both thefe differ from inchantmcni or forceries ; becaufe thole are perfonal conferences with the devil, and thefe are but medicines and ceremonious forms of words (commonly call- ed charms) without apparition.
