Never losing sight for one moment of our gracious & wise host - & his ordinance against stylistic disputes - I can only report that, but for Malcolm drawing attention to it, I would certainly have missed Jim's recommendation of the Calvino book. In my ignorance, I assumed he was making some arcane poetic allusion that sounded vaguely reminiscent of Frost or De la Mare. But for a typo a book was lost, but for a book a thesis was lost, but for a thesis a PhD was lost, but for a PhD a career was lost.... Scottie B.
