Although he had never before chanced to come across a case of aphasia (happily a rare disease), Hewitt was acquainted with its general nature. He knew that it might arise either from some physical injury to the brain, or from a break-down consequent on some terrible nervous strain. He knew that in the case of motor aphasia the sufferer, though fully conscious of all that goes on about him, and though quite understanding what is said to him is entirely powerless to put his own thoughts into spoken words--has lost, in fact, the connection between words and their spoken symbols. Also that in most bad cases agraphia--the loss of ability to write words with any reference to their meaning--is commonly an accompaniment. "You will have him taken to the infirmary, I suppose?" Hewitt asked. "Yes," the doctor replied. "I shall go and see about it at once." The man looked up again as they spoke. The policeman had, in accordance with Hewitt's request, placed a loaf of bread on the table near him, and now as he looked up he caught sight of it. He started visibly and paled, but gave no such signs of abject terror as the policeman had previously observed. He appeared nervous and uneasy, however, and presently reached stealthily toward the loaf. Hewitt continued to talk to the doctor, while closely watching the Frenchman's behaviour from the corner of his eye. The loaf was what is called a "plain cottage," of solid and regular shape. The man reached it and immediately turned it bottom up on the table. Then he sank back in his chair with a more contented expression, though his gaze was still directed toward the loaf. The policeman grinned silently at this curious manoeuvre. The doctor left, and Hewitt accompanied him to the door of the room. "He will not be moved just yet, I take it?" Hewitt asked as they parted. "It may take an hour or two," the doctor replied. "Are you anxious to keep him here?" "Not for long; but I think there's a curious inside to the case, and I may perhaps learn something of it by a little watching. But I can't spare very long." At a sign from Hewitt the loaf was removed. Then Hewitt pulled the small table closer to the Frenchman and pushed the pen and sheets of paper toward him. The manoeuvre had its result. The man looked up and down the room vacantly once or twice and then began to turn the papers over. From that he went to dipping the pen in the inkpot, and presently he was scribbling at random on the loose sheets. Hewitt affected to leave him entirely alone, and seemed to be absorbed in a contemplation of a photograph of a police-division brass band that hung on the wall, but he saw every scratch the man made.
