CONJURATION. A swearing together. It signifies a plot, bargain, or compact 
made by a number of persons under oath, to do some public harm. In times of 
ignorance, this word was used to signify the personal conference which some 
persons were supposed to have had with the devil, or some evil spirit, to 
know any secret, or effect any purpose.
