Elsworth was shown a number of beds, of the occupants of which he was required to write complete family histories, going into the minutest details, as practice in note-taking. He was called on to carry out, with the assistance of the nurses, daily, all the directions as to the dressings and bandaging required by the nature of the case; and was encouraged to avail himself, while doing so, of any and every means that would assist him in the acquisition of his art, so far as it was consistent with the regular treatment of the patient, and was not calculated to alarm him or make him think it was not actually connected with his cure. Our house surgeon was going in for ophthalmology, and he never missed an opportunity of dropping belladonna into every patient’s eyes, and taking stock of his retina with the ophthalmoscope. Whether you had cracked your skull or broken your leg, fractured a rib or sprained your ankle, your eyes must be examined minutely, on the chance of something pretty turning up to show the professor of ophthalmology. Dr. Wilson was such an enthusiast on eyes that one day, happening to pass through one of the out-patient wards, he caught sight of a working man in whose visual organs he instantly detected something of interest. Immediately he had him under a lamp, and set to work making sketches of the morbid appearances in the retina, explaining to the other students the beautiful things to be seen therein. Now the patient had not come about his eyes, but being troubled with indigestion, wanted a bottle of medicine to cure it; and he was naturally surprised that for three mortal hours eighteen young gentlemen should be examining his eyes, which wanted no treatment but the sight of a little more weekly pay; and marvelled that no questions should be asked him about the ailment which caused him discomfort. He was still more amazed when, as evening drew on, one after another went away, and nobody prescribed anything for him at all! However, one of the resident staff saw him before the place was closed, and he had a bottle of “house mixture,” and went away more satisfied; but still wondering at the singular ways of doctors. Let us go round the wards with Dr. Wilson and our hero, his new assistant.
