 Hopkins says he and nine other witnesses saw the first five of    these, which appeared in the forms described by the witch. Only    the first of these was a cat; the next two were dogs, and the    others were a black rabbit and a polecat. So its not clear    whether Pyewacket was a cats name or not. As for the meanings,    Hopkins says only that they were such that "no mortall could    invent." The incident is described in Hopkinss pamphlet "The    Discovery of Witches" (1647).
