"We were talking about nerve just now," observes the surgeon. "Just, after my qualifying I served in the Navy for a time, as I think you know. I was on the flag-ship on the West African Station, and I remember a singular example of nerve which came to my notice at that time. One of our small gunboats had gone up the Calabar river, and when there the surgeon died of coast fever. On the same day a man's leg was broken by a spar falling upon it, and it became quite obvious that it must be taken off above the knee if his life was to be saved. The young lieutenant who was in charge of the craft searched among the dead doctor's effects and laid his hands upon some chloroform, a hip-joint knife, and a volume of Grey's _Anatomy_. He had the man laid by the steward upon the cabin table, and with a picture of the cross section of the thigh in front of him he began to take off the limb. Every now and then, referring to the diagram, he would say: 'Stand by with the lashings, steward. There's blood on the chart about here.' Then he would jab with his knife until he cut the artery, and he and his assistant would tie it up before they went any further. In this way they gradually whittled the leg off, and upon my word they made a very excellent job of it. The man is hopping about the Portsmouth Yard at this day. "It's no joke when the doctor of one of these isolated gunboats himself falls ill," continues the surgeon after a pause. "You might think it easy for him to prescribe for himself, but this fever knocks you down like a club, and you haven't strength left to brush a mosquito off your face. I had a touch of it at Lagos, and I know what I am telling you. But there was a chum of mine who really had a curious experience. The whole crew gave him up, and, as they had never had a funeral aboard the ship, they began rehearsing the forms so as to be ready. They thought that he was unconscious, but he swears he could hear every word that passed. 'Corpse comin' up the 'atchway!' cried the cockney sergeant of Marines. 'Present harms!' He was so amused, and so indignant too, that he just made up his mind that he wouldn't be carried through that hatchway, and he wasn't, either." "There's no need for fiction in medicine," remarks Foster, "for the facts will always beat anything you can fancy. But it has seemed to me sometimes that a curious paper might be read at some of these meetings about the uses of medicine in popular fiction." "How?"
