Question No 3 [25]

Read the following passage and answer the questions that follow:

(1) I remember going to the British Museum one day to read up the treatment forsome slight ailment of which I had a touch hay fever, I fancy it was. I gotdown the book, and read all I came to read; and then, in an unthinkingmoment, I idly turned the leaves, and began to study diseases, generally. Iforget which was the first distemper I plunged into and, before I had glancedhalf down the list of premonitory symptoms, it was borne in upon me that Ihad fairly got it.

(2) I sat for a while frozen with horror; and then in despair, I again turned overthe pages. I came to typhoid fever read the symptoms discovered that Ihad typhoid fever, must have had it for months without knowing it wonderedwhat else I had got; turned up St Vituss Dance found, as I expected, that Ihad that too began to get interested in my case, and determined to sift it tothe bottom, and so started alphabetically read up ague, and learnt that I wassickening for it, and that the acute stage would commence in about a fortnight.Brights disease, I was relieved to find, I had only in a modified form, and, sofar 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 ploddedconscientiously through the twenty-six letters, and the only malady I couldconclude I had not got was housemaids knee.

(3) I felt rather hurt about this at first; it seemed somehow to be a sort ofslight. Why hadnt I got housemaids knee? After a while, however, lessgrasping feelings prevailed. I reflected that I had every other known malady inthe pharmacology, and I grew less selfish, and determined to do withouthousemaids knee. Gout, in its most malignant stage, it would appear, hadseized me without my being aware of it; and zymosis I had evidently beensuffering with from boyhood. There were no more diseases after zymosis, soI concluded there was nothing else the matter with me.

(4) I sat and pondered. I thought what an interesting case I must be from amedical point of view, what an acquisition I should be to a class! Studentswould have no need to walk the hospitals, if they had me. I was a hospital inmyself. All they need do would be to walk round me, and, after that, take theirdiploma.

(5) Then I wondered how long I had to live. I tried to examine myself. I feltmy pulse. I could not at first feel any pulse at all. Then, all of a sudden, itseemed to start off. I pulled out my watch and timed it. I made it a hundredand 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 thatit must have been there all the time, and must have been beating, but I cannotaccount for it. I patted myself all over my front, from what I call my waist up tomy head, and I went a bit round each side, and a little way up the back. But Icould not feel or hear anything. I tried to look at my tongue. I stuck it out as faras ever it would go, and I shut one eye, and tried to examine it with the other. Icould only see the tip, and the only thing that I could gain from that was to feelmore certain than before that I had scarlet fever.
