This is a medico-legal report on the condition of a lady arrested for repeated acts of fraud and theft. Her history is of interest. During the past twenty years she has been under treatment in Camberwell and Banstead Asylums in this country, in three asylums in America, and in many on the Continent. She was of good family (with a marked predisposition to phthisis and nervous disease) and highly educated. She was the authoress of two novels of the decadent type, which caused some talk when they were published in 1892. The chief difficulty in deciding the question of her responsibility arose from the largely negative results of her examination. The reports sent from the different institutions were vague and unsatisfactory, and no definite diagnosis had evidently been possible. Morphinism, hallucinations of hearing, and tendency to suicide were facts, however, stated in different reports. From the history and the great variety of the symptoms of her different illnesses, Professor Bianchi came to the conclusion that her condition had an hysterical basis, and that she was not responsible. This finding was accepted by the Tribunal. Subsequent symptoms also confirmed this diagnosis.
