Sir: R. Riley trots out the same complaint about students' lack of "general knowledge" that was levelled when I was a student 40 years ago and regularly since (and doubtless before) that time. There are two definitions of general knowledge: (i) things I know and think you ought to know too; (ii) things you've read up recently and I haven't. R. Riley clearly subscribes to the former. I recommend the latter to his daughter.
