“ This phenomenon, which resembles the insensitive patches that under the name of 'Devil's claws' were found upon witches when witchcraft was fashionable, has been long known as a sign of hysteria. There is now a tendency to ascribe it to suggestibility or, as I should prefer, to receptivity.In the early stage of the disease some one examines the arm, pricks it, and asks, 'Do you feel that?' It is my experience that the patient sometimes flinches at the first prick, but answers 'No', and until this newly-implanted belief is removed he never flinches again when the limb is pricked. ”
