Forbes, the great Scotch lawyer, says that 'to some he [the Devil] gives certain Spirits or Imps to correspond with, and serve them as their Familiars, known to them by some odd Names, to which they answer when called. These Imps are said to be kept in Pots or other Vessels.'[839] Though the domestic familiar is thus mentioned in the law of Scotland, it never occurs in the trials. It is confined so strictly to England that Hutchinson is able to say 'I meet with little mention of _Imps_ in any Country but ours, where the Law makes the feeding, suckling, or rewarding of them to be Felony'.[840] It is not found north of Lancashire, and the chief records are in Essex, Suffolk, and the other Eastern counties. The domestic familiar was always a small animal, was fed in a special manner on bread and milk and blood, and was kept, as Forbes points out, in a box or earthen pot on a bed of wool. It was used for working magic on the persons and property of other people, never for divining. Giffard records the general belief: 'The witches have their spirits, some hath one, some hath more, as two, three, foure, or five, some in one likenesse, and some in another, as like cats, weasils, toades, or mise, whom they nourish with milke or with a chicken, or by letting them suck now and then a drop of bloud.'[841] In the earlier trials the witches confessed to pricking the hands or face and giving the resulting drop or drops of blood to the familiar. In the later trials this has developed into the sucking of the witch's blood by the familiar; and the supernumerary nipple, which was so marked a feature of the English witches, was popularly supposed to be caused by such sucking. It is more probable, however, that the witch who was possessed of a supernumerary nipple would regard it as something supernatural, and would use it to nourish a supernatural animal.
