There he is, bent over the page, with a monocle in his right eye, wholly devoted to the noble but rugged task of ferreting out the error. He has already promised himself to write a little monograph in which he will relate the finding of the book and the discovery of the error, if there really is one hidden there. In the end, he discovers nothing and contents himself with possession of the book. He closes it, gazes at it, gazes at it again, goes to the window and holds it in the sun. The only copy! At this moment a Caesar or a Cromwell passes beneath his window, on the road to power and glory. He turns his back, closes the window, stretches in his hammock, and fingers the leaves of the book slowly, lovingly, tasting it sip by sip...An only copy!
