With apparent reluctance the well-known physician rose, after being cordially welcomed to the platform by the French savant, adjusted his old-fashioned glasses, and commenced to introduce the subject. His appearance there was certainly quite unexpected, but as I glanced at Ambler I saw a look of triumph in his face. We were sitting at the back of the hall, and I knew that Sir Bernard, being short-sighted, could not recognise us at the distance. "I am here at Doctor Fulton's invitation to meet our great master, Professor Deboutin, of whom for many years I have been a follower." Then he went on to express the pleasure it gave him to demonstrate before them a case which he declared was not at all uncommon, although hitherto unsuspected by medical men. Behind the chair of the new-comer stood the strange-looking old lady--who answered for her grand-daughter, the latter being mute. Her case was one, Sir Bernard explained, of absence of will. With a few quick questions he placed the history of the case before his hearers. There was a bad family history--a father who drank, and a mother who suffered from epilepsy. At thirteen the girl had received a sudden fright owing to a practical joke, and from that moment she gradually came under the influence of some hidden unknown terror so that she even refused to eat altogether. The strangest fact, however, was that she could still eat and speak in secret, although in public she was entirely dumb, and no amount of pleasure or pain would induce her to utter a sound. "This," explained Sir Bernard, "is one of the many cases of absence of will, partial or entire, which has recently come beneath my notice. My medical friends, and also Professor Deboutin, will agree that at the age the patient received her fright many girls are apt to tend towards what the Charcot School term 'aboulie,' or, in plain English, absence of will. Now one of the most extraordinary symptoms of this is terror. Terror," he said, "of performing the simplest functions of nature; terror of movement, terror of eating--though sane in every other respect. Some there are, too, in whom this terror is developed upon one point only, and in such the inequality of mental balance can, as a rule, only be detected by one who has made deep research in this particular branch of nervous disorders." The French professor followed with a lengthy discourse, in which he bestowed the highest praise upon Sir Bernard for his long and patient experiments, which, he said, had up to the present been conducted in secret, because he feared that if it were known he had taken up that branch of medical science he might lose his reputation as a lady's doctor. Then, just as the meeting was being brought to a conclusion, Jevons touched me on the shoulder, and we both slipped out. "Well," he asked. "What do you think of it all?" "I've been highly interested," I replied. "But how does this further our inquiries, or throw any light on the tragedy?"
