his father), the duration of a prayer delivered by his father (30 minutes or merely 15), the location of the supposed "Imp" (on M. Rule's belly or on her pillow), and whether M. Rule's upper-body was covered by "bed-clothes" i.e. sheet and blankets, or merely by her own "cloaths." CM writes "For you cannot but know how much this representation hath contributed, to make people believe a smutty thing of me ..." Calef in responding, considers any discrepancies minor, and shows great impatience with CM for not addressing the more important theological "doctrinals" underpinning his belief in witchcraft. CM sends a messenger to Calef to read a letter aloud and on another occasion CM sends Calef a letter but says it must be returned in a fortnight and "which he forbad to be Copyed." NOTE, this letter was later found, including marginalia in Calef's hand, and a typescript can be viewed beginning page 240 here Part III: A compilation of letters between Samuel Parris and his congregation, especially the relatives and survivors of those who were tried and executed. Part IV: Correspondence with an anonymous gentleman "endevouring to prove the received opinions about Witchcraft" Part V: A compilation of numerous testimonies and legal documents from the trials, including: 1696 apology from one of the judges saying "he was apprehensive that he might have fallen into some Errors in the Matters at Salem" and A letter signed by 12 members of the jury at Salem, "We do heartily ask forgiveness of you all ... and do declare according to our present minds, we would none of us do such things again on such grounds for the whole World ..." CM's own preface to Wonders of the Invisible World and some portions of it. Postscript: Calef adds to his book a sharp response to a posthumous biography of Sir William Phips anonymously written by Cotton Mather which arrived in Boston in December 1697. Clive Holmes writes, "[Cotton Mather's] studied attempt to displace responsibility onto civil authorities was brilliantly diagnosed and savaged by Calef in his comments on the 1697 Life of Phips." Printing in London and reception in New England For his own book, Calef used the same printer employed by Cotton Mather for his anonymous 1697 Life of Phips, perhaps in an effort to reach the same audience. Cotton Mather records a date when Calef's manuscript shipped to London, June 10,
