A delightful quote, cribbed from Anatoly:
Professor Edgeworth, of All Souls’, avoided conversational English, persistently using words and phrases that one expects to meet only in books. One evening, Lawrence returned from a visit to London, and Edgeworth met him at the gate. “Was it very caliginous in the Metropolis?”
“Somewhat caliginous, but not altogether inspissated”, Lawrence replied gravely.
—Robert Graves, Good-Bye to All That, p. 372.
I presume this is the Edgeworth in question; this biographical sketch includes a nice quote: “Besides we owe him something, like a good German he knew that the Greek k is not a modern c, and, if any of you at any time wonder where the k in Biometrika comes from, I will frankly confess that I stole it from Edgeworth. Whenever you see that k call to mind dear old Edgeworth.”
