September 13, 1930. Dr. med. A. Kielholz, Königsfelden: 'Murder by poisoning and the delusion of being poisoned'. Close psychological connection between the two—mutually complementary. Important part played by incest and impregnation. Struggle for sole possession of the mother's body—its secretions and excretions are magical substances providing poisons for the killing of hated rivals. In the delusion of being poisoned, this struggle is introjected into the subject's own person. The struggle projected by the poisoner on to the symbolic representation of the mother's body. Reason why the secretions and excretions are so deadly and poisonous; their acquisition and possession equated with incest—punishment by castration and death.
