(Boston: Little, Brown and Company, 1939), pp. 187-188:
This ideal of endowment for research was particularly shocking to Benjamin Jowett, the great inventor of the tutorial system which it threatened. I remember once, when staying with him at Malvern, inadvertently pronouncing the ill-omened word. "Research!" the Master exclaimed. "Research!" he said. "A mere excuse for idleness; it has never achieved, and will never achieve, any results of the slightest value." At this sweeping statement I protested, whereupon I was peremptorily told, if I knew of any such results of value, to name them without delay. My ideas on the subject were by no means profound, and anyhow it is difficult to give definite instances of a general proposition at a moment's notice. The only thing that came into my head was the recent discovery, of which I had read somewhere, that on striking a patient's kneecap sharply he would give an involuntary kick, and that by the vigor or lack of vigor of this "knee jerk," as it is called, a judgment could be formed of his general state of health.
"I don't believe a word of it," Jowett replied. "Just give my knee a tap."
I was extremely reluctant to perform this irreverent act upon his person, but the Master angrily insisted, and the undergraduate could do nothing but obey. The little leg reacted with a vigor which almost alarmed me, and must, I think, have considerably disconcerted that elderly and eminent opponent of research.
