"I was in practice at the time. One morning a Mrs. Cooper called upon me and informed me that her husband had shown signs of delusions lately. They took the form of imagining that he had been in the army and had distinguished himself very much. As a matter of fact he was a lawyer and had never been out of England. Mrs. Cooper was of opinion that if I were to call it might alarm him, so it was agreed between us that she should send him up in the evening on some pretext to my consulting-room, which would give me the opportunity of having a chat with him and, if I were convinced of his insanity, of signing his certificate. Another doctor had already signed, so that it only needed my concurrence to have him placed under treatment. Well, Mr. Cooper arrived in the evening about half an hour before I had expected him, and consulted me as to some malarious symptoms from which he said that he suffered. According to his account he had just returned from the Abyssinian Campaign, and had been one of the first of the British forces to enter Magdala. No delusion could possibly be more marked, for he would talk of little else, so I filled in the papers without the slightest hesitation. When his wife arrived, after he had left, I put some questions to her to complete the form. 'What is his age?' I asked. 'Fifty,' said she. 'Fifty!' I cried. 'Why, the man I examined could not have been more than thirty! And so it came out that the real Mr. Cooper had never called upon me at all, but that by one of those coincidences which take a man's breath away another Cooper, who really was a very distinguished young officer of artillery, had come in to consult me. My pen was wet to sign the paper when I discovered it," says Dr. Manson, mopping his forehead.
