My knowledge of the thing began in the winter of 1926-27 with the death of my grand-uncle, George Gammell Angell, Professor Emeritus of Semitic languages in Brown University, Providence, Rhode Island. Professor Angell was widely known as an authority on ancient inscriptions, and had frequently been resorted to by the heads of prominent museums; so that his passing at the age of ninety-two may be recalled by many. Locally, interest was intensified by the obscurity of the cause of death. The professor had been stricken whilst returning from the Newport boat; falling suddenly, as witnesses said, after having been jostled by a nautical-looking negro who had come from one of the queer dark courts on the precipitous hillside which formed a short cut from the waterfront to the deceased’s home in Williams Street. Physicians were unable to find any visible disorder, but concluded after perplexed debate that some obscure lesion of the heart, induced by the brisk ascent of so steep a hill by so elderly a man, was responsible for the end. At the time I saw no reason to dissent from this dictum, but latterly I am inclined to wonder—and more than wonder.
