"It is a most extraordinary thing, but I never read a patent medicine advertisement without being impelled to the conclusion that I am suffering from the particular disease therein dealt with in its most virulent form. The diagnosis seems in every case to correspond exactly with all the sensations that I have ever felt.
 
I remember going to the British Museum one day to read up the treatment for some slight ailment of which I had a touch--hay fever, I fancy it was. I got down the book, and read all I came to read; and then, in an unthinking moment, I idly turned the leaves, and began to indolently study diseases, generally. I forget which was the first distemper I plunged into--some fearful, devastating scourge, I know--and, before I had glanced half down the list of "premonitory symptoms," it was borne in upon me that I had fairly got it.
 
I sat for awhile, frozen with horror; and then, in the listlessness of despair, I again turned over the pages. I came to typhoid fever--read the symptoms--discovered that I had typhoid fever, must have had it for months without knowing it--wondered what else I had got; turned up St. Vitus's Dance--found, as I expected, that I had that too,--began to get interested in my case, and determined to sift it to the bottom, and so started alphabetically--read up ague, and learnt that I was sickening for it, and that the acute stage would commence in about another fortnight. Bright's disease, I was relieved to find, I had only in a modified form, and, so far as that was concerned, I might live for years. Cholera I had, with severe complications; and diphtheria I seemed to have been born with. I plodded conscientiously through the twenty-six letters, and the only malady I could conclude I had not got was housemaid's knee.
 
I felt rather hurt about this at first; it seemed somehow to be a sort of slight. Why hadn't I got housemaid's knee? Why this invidious reservation? After a while, however, less grasping feelings prevailed. I reflected that I had every other known malady in the pharmacology, and I grew less selfish, and determined to do without housemaid's knee. Gout, in its most malignant stage, it would appear, had seized me without my being aware of it; and zymosis I had evidently been suffering with from boyhood. There were no more diseases after zymosis, so I concluded there was nothing else the matter with me.
 
I sat and pondered. I thought what an interesting case I must be from a medical point of view, what an acquisition I should be to a class! Students would have no need to "walk the hospitals," if they had me. I was a hospital in myself. All they need do would be to walk round me, and, after that, take their diploma.
 
Then I wondered how long I had to live. I tried to examine myself. I felt my pulse. I could not at first feel any pulse at all. Then, all of a sudden, it seemed to start off. I pulled out my watch and timed it. I made it a hundred and forty-seven to the minute. I tried to feel my heart. I could not feel my heart. It had stopped beating. I have since been induced to come to the opinion that it must have been there all the time, and must have been beating, but I cannot account for it. I patted myself all over my front, from what I call my waist up to my head, and I went a bit round each side, and a little way up the back. But I could not feel or hear anything. I tried to look at my tongue. I stuck it out as far as ever it would go, and I shut one eye, and tried to examine it with the other. I could only see the tip, and the only thing that I could gain from that was to feel more certain than before that I had scarlet fever.
 
I had walked into that reading-room a happy, healthy man. I crawled out a decrepit wreck.
 
I went to my medical man. He is an old chum of mine, and feels my pulse, and looks at my tongue, and talks about the weather, all for nothing, when I fancy I'm ill; so I thought I would do him a good turn by going to him now. "What a doctor wants," I said, "is practice. He shall have me. He will get more practice out of me than out of seventeen hundred of your ordinary, commonplace patients, with only one or two diseases each." So I went straight up and saw him, and he said:
 
"Well, what's the matter with you?"
 
I said:
 
"I will not take up your time, dear boy, with telling you what is the matter with me. Life is brief, and you might pass away before I had finished. But I will tell you what is not the matter with me. I have not got housemaid's knee. Why I have not got housemaid's knee, I cannot tell you; but the fact remains that I have not got it. Everything else, however, I have got."
 
And I told him how I came to discover it all.
 
Then he opened me and looked down me, and clutched hold of my wrist, and then he hit me over the chest when I wasn't expecting it--a cowardly thing to do, I call it--and immediately afterwards butted me with the side of his head. After that, he sat down and wrote out a prescription, and folded it up and gave it me, and I put it in my pocket and went out.
 
I did not open it. I took it to the nearest chemist's, and handed it in. The man read it, and then handed it back.
 
He said he didn't keep it.
 
I said:
 
"You are a chemist?"
 
He said:
 
"I am a chemist. If I was a co-operative stores and family hotel combined, I might be able to oblige you. Being only a chemist hampers me."
 
I read the prescription. It ran:
 
    * "1 lb. beefsteak, with 1 pt. bitter beer every 6 hours.
    * 1 ten-mile walk every morning.
    * 1 bed at 11 sharp every night.
    * And don't stuff up your head with things you don't understand."
 
I followed the directions, with the happy result--speaking for myself--that my life was preserved, and is still going on."
