In an extremely interesting and clearly written way a condensed report is given of psychoanalytic data showing certain determinents of the preconvulsive auræ of two patients. Limiting his conclusions strictly to the observations of two patients, the author states: 'In these two cases the auræ were conscious vestiges of neurotically precipitated anxiety attacks occurring before the onset of seizures. The repetition of these attacks was inhibited and in consequence of this, discharge through the central nervous system replaced the discharge of autonomic tension as an anxiety symptom. The relationship between the convulsions of these two patients and the preëpileptic anxiety syndromes are definite, and the function of the aura as an aborted tendency to repeat this experience seems probable.'
